Accessible Trader: Quick Start Guide

For Blind and Visually Impaired Traders

This guide is for new users who want to understand how Accessible Trader works, how to navigate it by keyboard, and how to interpret the audio and speech feedback the application provides. No prior experience with trading software is required to read this guide, though familiarity with financial markets and charting concepts will help.

1. What Is Accessible Trader?

Accessible Trader is a professional trading terminal built from the ground up for blind and visually impaired traders. It runs on Windows, Android, iOS, and Mac and gives you access to real-time and historical market data across stocks, crypto, forex, and other instruments.

The application is entirely keyboard-driven. You do not need a mouse at any point. Every function — from placing a drawing tool to configuring an indicator's audio properties — is reachable through keyboard shortcuts.

Accessible Trader pairs your existing screen reader (NVDA, JAWS, Narrator, VoiceOver, or TalkBack) with its own built-in audio engine to give you two complementary layers of information simultaneously:

• Your screen reader announces exact values: price, time, indicator readings.
• The built-in audio engine plays continuous sound that reflects the shape and movement of the market.

Together these two layers let you perceive both precise numbers and broad market structure at the same time — something no conventional chart can offer.

2. The Hybrid Voice Model

Accessible Trader uses what is called the Hybrid Voice model. This is the core design principle of the application, and understanding it will help you get the most out of every session.

Screen reader (your existing tool) handles:

• Exact price values when you land on a bar
• Exact indicator readings when you navigate to a component
• Dialog labels, menu items, setting names, and all text content
• Confirmation messages after actions

Built-in sonification engine handles:

• The pitch contour of price as it moves left to right through time
• The tonal texture of oscillator indicators — how overbought, how oversold, how far from zero
• Distinct bell tones for specific signal events (crossovers, divergences, confluence zones, support and resistance levels)
• Stereo position: bars on the left side of the visible window play in the left channel; bars on the right side play in the right channel
• Volume scaling: louder sounds indicate larger, more significant movements

Neither system replaces the other. When you play back a chart, you hear both simultaneously: your screen reader announces each bar's values while the audio engine plays that bar's sonic shape.

Optional third layer — refreshable tactile graphics. If you have a Dot Pad, the terminal can also render the chart's shape under your fingers. All Dot Pad models are supported — the Dot Pad X (newest) and the second generation — because they share the same graphics SDK. This is a Windows-only feature and needs a one-time SDK install; see the "Tactile Display" chapter of the User Manual and PLATFORMS.md §7 for setup.

3. Understanding the Soundscape

Pitch

Pitch maps directly to value. Higher pitch means a higher price or a higher oscillator reading. Lower pitch means lower. When a price trend is rising, you hear a rising pitch. When it falls, the pitch falls with it.

For oscillators (indicators that have a center line, such as MACD or RSI), the pitch rises above a mid-point for positive values and falls below for negative values.

Waveform (Timbre)

The type of sound — its tonal color — changes based on where a value sits relative to key thresholds.

• Every sound is built on a warm sine base, with a slight coloring blended in rather than a whole different waveform.
• When an oscillator is above its midline, the tone takes on a brighter, slightly reedy square coloring; below the midline it takes on a softer, warmer triangle coloring — so you can hear which side you are on without checking a number.
• When a value pushes into an overbought or oversold zone on a bounded oscillator (RSI, Stochastics, MFI, CCI, Williams %R, or the Ultimate Oscillator), a noticeable noise texture roughens the tone so you can hear the extremity without checking a number. You can set how strong this roughness is per level with the Zone Texture slider in the indicator's properties dialog, under Reference Levels.

This means you can often tell at a glance — or rather, at a listen — not just what the value is but where it sits relative to the structure of the indicator.

Bell Tones

When the playback cursor lands on a bar that contains a signal event, you hear a short bell tone in addition to the continuous oscillator sound. Different signal types have distinct bell timbres so you can tell them apart by ear:

• Sine bell: smooth and clear — typically marks crossover events
• Triangle bell: bright and metallic — typically marks divergence signals
• Crystal bell: high and pure — typically marks support and resistance levels
• Detuned pair bell: a slightly shimmering double tone — typically marks high-confluence signals
• Gradient blend bell: a rich, multi-harmonic tone — typically marks momentum signals

When you encounter a bell tone during playback, you can stop playback and read the exact event details through your screen reader.

Stereo Panning

As playback moves forward in time, or as you move the cursor right, the sound moves from the left channel toward the right channel. The leftmost visible bar on screen is hard left; the rightmost is hard right. This gives you an immediate spatial sense of where you are in the visible window, even without a screen reader announcement.

Volume Layers

The audio engine organizes sounds into three depth layers:

• Background layer (quieter): longer-term context sounds, such as broad trend lines
• Midground layer (medium): main oscillator and price tones
• Foreground layer (loudest): signals and event bells

This layering lets important signals cut through the continuous background without the two competing at the same volume.

4. Getting Started: The Chart Layout

When you open Accessible Trader, the main chart area is divided into panes stacked vertically:

• The top pane is always the price chart (candlestick bars by default).
• Below it are indicator panes — one for each indicator that has its own separate display area.
• Some indicators appear as overlays directly on the price chart (such as moving averages); they do not get their own pane.

Each pane can contain one or more series. Each series can contain one or more components. For example:

• A pane might contain a MACD indicator (one series).
• That MACD series has three components: the MACD line, the signal line, and the histogram.
• You navigate between these components with the Up and Down arrow keys.

Understanding this three-level hierarchy — panes, series, components — is the key to navigating the chart confidently.

Choosing what to chart

Above the chart is the toolbar. Its second row is the selection cascade: Market → Provider → Symbol → timeframe → Load. To chart data feeds instead of a tradeable instrument, choose Analytics in the Market dropdown; an extra Analytics type dropdown then appears (Economic, OnChain, Derivatives, Sentiment) before Provider. There is no separate "Trading vs Analytics" switch — the Market dropdown is the single place you choose between the two.

Which API keys to get first

You can chart crypto the minute you install this and never enter a key. Everything else is worth adding in roughly this order — each step unlocks more than the one after it, and the first four are free.

Start here — no key needed at all. Crypto price data works out of the box: Bitstamp, Kraken, Kraken Futures, Gemini, MEXC and Binance all serve market data without credentials. So do a surprising number of the analytics feeds: CoinGecko (coin profiles, the crypto half of the Alt+I dossier), SEC EDGAR (US company filings, the equity half of the dossier), Alternative.me (Fear & Greed), CoinMetrics (on-chain), FINRA (daily short volume for any US stock), CFTC (Commitments of Traders), Binance Vision (funding and open interest), DefiLlama, Mempool, Deribit, OKX, and Wikipedia pageviews (retail attention). That is most of the analytics layer, for nothing.

1. Alpaca — free, and the single biggest unlock. This is the one to get first if you touch US markets at all. It brings 14,162 active US equities and ETFs, including 1,136 OTC symbols, with 5-minute intraday history back to 2016 — so esoteric tickers, the leveraged and thematic ETFs, and small caps are all covered. The same key also gives you a paper trading account, which is how you should practise the order panel before any real money is involved. Sign up at alpaca.markets; you get a paper key pair and a live key pair. Enter the paper pair first, and only add the live pair when you actually intend to trade with it.

Alpaca covers ETFs but not indices. There is no SPX. Use the fund that tracks the index instead — SPY, QQQ, IWM, DIA — and for metals and bonds use GLD, SLV, TLT, IEF. One trap worth knowing: typing ES expecting the S&P futures contract returns Eversource Energy, a utility stock trading around $72. It is a valid symbol, so nothing will warn you.

2. FRED — free, instant, and the whole macro picture. A St. Louis Fed key (fred.stlouisfed.org, issued immediately) turns on the Economic analytics provider: CPI, unemployment, yield curves, the Fed funds rate, and hundreds of other series you can chart beside price like any indicator.

3. TwelveData — free tier, for what Alpaca cannot reach. Spot gold (XAU/USD) works on the free tier and is genuinely useful. Be aware that on the free plan SPX and XAG/USD (spot silver) are not included — they need a paid tier — so do not be surprised when they fail.

4. An AI provider — optional, and only for the AI Analyst. Claude, OpenAI or a local Ollama install. Nothing else in the terminal uses it, no strategy or alert depends on it, and your chart data leaves your machine when you use it. A local Ollama install avoids that entirely.

Later, and only if you need them. Coinbase, Schwab, Tradier, Oanda and Interactive Brokers are for placing real orders through a broker you already have. Polygon, Finnhub and FMP are paid data vendors that overlap heavily with what Alpaca already gives you free — add one only when you hit a specific gap. Glassnode and Etherscan are paid or rate-limited on-chain sources, and the free CoinMetrics and Mempool feeds cover most of the same ground.

Keys go in the API key manager, Alt+K. They are stored on your own machine, never sent anywhere except the provider they belong to, and each provider tells you plainly when a key is missing rather than failing quietly.

5. Moving Through Time: Bar-by-Bar Navigation

The Basics

When you move left or right, your screen reader announces the bar's data. If you are on the price pane, it announces the open, high, low, and close of that candle. If you are focused on an indicator component, it announces that component's value for the current bar.

Simultaneously, the audio engine plays the sonified tone for that bar.

Scrolling the Viewport

Moving the cursor with Left and Right eventually reaches the edges of the visible window and causes the viewport to scroll automatically, keeping the cursor in view.

You can also scroll the viewport independently of the cursor:

Zooming

Zooming in shows you finer detail on fewer bars. Zooming out shows you broader context across more bars.

With the mouse

The chart toolbar also has Pan left, Pan right, Zoom in, and Zoom out buttons that do exactly what the keys above do (and announce the new visible range, so they're screen-reader friendly). And when no drawing tool is selected, you can click and drag the chart to pan it — drag right to bring older bars into view. Release the button anywhere to stop.

6. Moving Between Panes and Components

Switching Panes

When you switch panes, speech announces the name of the newly focused series (for example, "RSI" or "Volume").

Switching Components Within a Series

For example, if you are in a MACD pane, Down Arrow moves from the MACD line to the signal line to the histogram, and Up Arrow moves back up through them.

Speech announces the component name and its value at the current bar when you move to it. The audio engine simultaneously plays that component's tone.

Announcing Context

7. Jumping to Signals: Ctrl+Left and Ctrl+Right

Bar-by-bar navigation is precise but slow when you want to scan for events. Ctrl+Left and Ctrl+Right perform context-aware jumps based on what component you currently have focused.

When you reach a boundary in either direction with no more events, speech announces: "No more [component name] signals in this direction."

This navigation mode is designed for rapid scanning. For example, you can press Ctrl+Right repeatedly to step through every RSI overbought entry since the chart's beginning, or through every instance where price crossed a moving average.

8. Playback: Listening to the Market

Playback is the core listening mode. When you start playback, the chart animates bar by bar through the visible window while the audio engine plays the sonified representation of each bar. Your screen reader announces each bar's values as the cursor advances.

Playback Scopes

There are three playback scopes, controlling how much of the chart you hear:

Use whole-chart playback for a broad overview. Use focused series playback when you want to study one indicator without the noise of others. Use focused component playback when you want to isolate a single line — for example, just the RSI line by itself.

Whole-chart playback layers every visible, unmuted series at once, and each series sounds all of its own visible, unmuted components together — including soft cloud- and ribbon-fill sounds (such as an EMA Fill between two averages) that used to drop out when too many voices were playing. Muting a series or component (M) or hiding it (H) simply removes it from the mix, so you can thin a crowded soundscape down to what matters.

Pause, Resume, and Stop

When you pause with Ctrl+Space, playback now falls fully silent instead of holding the last chord. The arrow keys still audition individual bars while paused, so you can inspect the frozen moment before resuming.

Playback Speed

Speed affects how quickly the cursor advances through bars. At slower speeds you hear each bar more fully. At faster speeds you can scan a long history quickly.

9. Controlling Volume and Speech

Speech Toggle

You can run with speech only, audio only, or both simultaneously, depending on your preference and task.

Volume Controls

Volume is controlled at three levels: per component, per series, and master chart volume.

Component volume adjusts just the one component you have focused (for example, just the histogram within MACD). Series volume adjusts all components in the focused series together. Master volume adjusts everything.

Muting and Hiding

Muting silences the audio for that series without removing it from the chart. Hiding removes it from visual display and silences it. Both are toggles — pressing the same key again restores it.

10. Working with Indicators

Adding an Indicator

Press Alt+A to open the Add Indicator dialog. Indicators are organized in categories:

• Multi-Signal: indicators that produce several different types of signals from a single calculation
• Trend: moving averages and directional tools
• Momentum: oscillators that measure speed and rate of change
• Volatility: indicators that measure the range or dispersion of price
• Volume: indicators that incorporate trading volume into their analysis
• Profiles: volume profile and time-price opportunity tools

Navigate the category list and indicator list with the arrow keys. Press Enter to add an indicator.

When an indicator is added, it is automatically assigned audio properties based on its type. You can adjust these in the indicator's properties dialog.

Navigating to an Indicator

Use Page Down from the price chart to move focus through indicator panes in order. Use Page Up to move back up. When you land on an indicator pane, speech announces the indicator name and the value of its primary component at the current bar.

Exploring Components Within an Indicator

Press Down Arrow to move through the components of the focused indicator. Each component is a distinct output of the indicator — for example, the fast line, slow line, and signal line of a multi-line indicator. Speech announces the component name and value as you move to each one.

Adding a Reference Line

When focused on any indicator pane, press 0 (zero) to add a zero-level horizontal reference line to that indicator. This line will be audible during playback and will be used for zero-crossing navigation via Ctrl+Left/Right.

Opening Indicator Properties

In the properties dialog you can adjust:

• Calculation parameters (periods, smoothing factors, thresholds)
• Per-component colors (for sighted collaborators)
• Per-component audio settings (on the Sonification tab): a Sound Patch dropdown listing built-in bell patches plus any patch you have built in the Sound Designer, each with a ▶ preview button, and fallback waveform, noise, and volume controls used when no patch is chosen. Directional, green/red components (candles, bars, histograms and volume bars) also get separate Green (bullish) and Red (bearish) patch dropdowns, so up-bars and down-bars can sound different; plain lines and areas show only the single patch
• "Save as Defaults" — saves your preferred settings so new instances of this indicator start with the same configuration

Navigate the properties dialog with Tab and the arrow keys. Your screen reader reads all labels and current values.

Removing an Indicator

Press Delete while focused on an indicator pane to remove that indicator from the chart. Speech asks for confirmation. The price candle pane cannot be removed.

Heikin-Ashi Candles

Press Alt+C to toggle Heikin-Ashi candle mode on the price chart. Heikin-Ashi candles are a smoothed candlestick formula that reduces noise and can make trends easier to hear.

Logarithmic Scale

Press Alt+L to toggle logarithmic (log) scale on the price chart. Log scale is useful for long historical views where price has moved by very large percentages, as it compresses large ranges into a more even distribution.

11. Drawing Tools

Drawing tools let you place reference lines and shapes on the chart that are then audible during navigation and playback — for example, the cursor will announce when it crosses a trendline you have placed.

All drawing tools use sequential anchoring. You do not hold keys and drag, and you do not press Enter. Instead you navigate the cursor to the point you want and press the same drawing shortcut again to set each anchor at the current bar. This makes every drawing tool fully accessible.

The Sequential Anchoring Workflow

Take a trendline (Ctrl+Shift+T) as the example:

1. Navigate the cursor to the first point using the Left and Right arrows.
2. Press the drawing shortcut (Ctrl+Shift+T) to set the first anchor at the current bar. Speech announces the price and timestamp of the anchor and tells you what to do next — for example: "Trend line: anchor 1 set at 42,500.00, 14:30. Navigate to next point and press the shortcut again."
3. Navigate to the second point.
4. Press the same shortcut again (Ctrl+Shift+T) to set the second anchor and complete the drawing. Speech announces the completed drawing: for example, "Trend line placed from 42,500.00 to 43,100.00."
5. For three-anchor tools (Fibonacci extension, Risk/Reward, Andrews' pitchfork), repeat: navigate, then press the shortcut a third time to set the final anchor.
6. Press Escape at any time during placement to cancel the in-progress drawing.

Single-anchor tools (horizontal line, vertical line, text label, anchored VWAP) complete on the first press — they place immediately at the current bar.

Note: Enter does not confirm anchors. Each anchor is set by pressing the tool's own shortcut again. (If you have a mouse, you can also click or drag to place anchors, and drag an existing anchor handle to reposition it — but the keyboard workflow above is the primary, fully accessible path.)

Drawing Shortcuts

Linux web host users: every Ctrl+Shift+<letter> chord below becomes Alt+Shift+<letter> in the browser (Firefox reserves several Ctrl+Shift chords at the browser level). Same letter, same tool — see Platform Support. The desktop/mobile apps use Ctrl+Shift as shown.

Fibonacci Retracement

After placing 2 anchors (for example, from a swing low to a swing high), the application places horizontal levels at standard Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%). These levels are then audible as the cursor crosses them and are used as trendline-crossing events for Ctrl+Left/Right navigation when focused on the price series.

Anchored VWAP

The Anchored VWAP tool (Ctrl+Shift+W) places a Volume Weighted Average Price line starting from the bar you anchor it to and extending to the latest bar. It behaves like a moving average overlay — you can focus on it with Up/Down, and price/VWAP crossings are navigable with Ctrl+Left/Right.

Risk/Reward Tool

Ctrl+Shift+P starts the Risk/Reward tool. After you set the entry and stop-loss anchors, speech announces the resulting risk amount and asks you to set the target. When the target is set, speech announces the full risk-to-reward ratio.

12. Analysis, AI, and Context

Detailed Point Analysis

This announces:

• The candle's open, high, low, close, and volume
• Any recognized candlestick patterns at this bar (for example, "Engulfing bullish pattern")
• The readings of all active indicators at this bar
• Any signal events on this bar across all active indicators

This is useful for a thorough understanding of a specific bar before making a decision.

Context Summary

AI Technical Analyst

The AI Analyst sends a snapshot of the current chart — recent candle data, a summary of your active indicators, and (where the provider supports vision) an image of the chart — to a large language model and reads back a concise, plain-language technical analysis written for text-to-speech: trend direction, key support/resistance levels, momentum signals, and a short-term outlook.

To use it you must first add an API key for at least one AI provider in the API key manager (Alt+K). Supported providers are tried in order — Claude, then OpenAI, then Ollama — and the first one you have configured is used. If no key is configured, the Analyst tells you so rather than failing silently. Because the request goes to an external service, only use it with a provider you trust with your chart data.

Auto-Narration

Auto-narration watches the focused indicator series and speaks new signals and zone transitions as they occur on live bar closes — for example, a fresh marker firing, or an oscillator entering or leaving an overbought/oversold zone. Only signals that appear after you enable narration are announced; pre-existing historical signals are not replayed. Toggle it per series, so you can leave narration running on the one indicator you care about without being interrupted by the rest of the chart.

The Journal

The Journal is a persistent, screen-reader-friendly record of everything the application has spoken or alerted on during the current session — speech, alerts, strategy setups, errors, and backtest results. It is the primary tool for reviewing things that scrolled past in speech. The view is a monospace text area you can Tab into to read or copy any line, with filter buttons (All / Speech / Alerts / Setups / Errors / Backtests) and a "Copy visible" button. The buffer holds up to 2000 entries, newest at the bottom. Composite-strategy setups appear with their full rationale — side, score, stop price, first target, risk/reward, and stop placement notes.

13. Modals, Panels, and Dialogs

All modals and panels are opened by keyboard shortcut and navigated with Tab, Shift+Tab, and the arrow keys. Your screen reader reads all labels. Press Escape to close any dialog.

Help Dialog (F1)

Press F1 at any time to open the built-in keyboard reference. This lists every shortcut in the application. It is readable by your screen reader in full.

Settings (F12)

The Settings dialog contains tabs for:

• General preferences (default symbol, timeframe, provider)
• Audio preferences (default waveforms, playback speed, bell patch assignments)
• Accessibility preferences (screen reader integration mode, speech rate adjustments)
• Connection settings (data provider configuration)

Market watch (Alt+M)

Three tabs. Watchlists keeps named, ordered sets of symbols — pick them from the provider's real symbol list through the same Market → Provider → Sub-type → Symbol cascade the toolbar uses, with a filter box for large universes and a live count of how many symbols are showing out of how many exist. Build a screen creates a saved screen from filter rows (indicator → component → condition → values), combined by all / any / weighted score; each row is restated in plain English underneath. Run screener runs a screen against a watchlist and returns a table you can move through cell by cell. Symbols that could not be evaluated are always reported, never dropped.

Respect report (Alt+R)

Measures which lines this market actually reacts to, rather than assuming. Two tabs — levels near price, and a moving-average ranking — each reporting hold rate, touch count, median reaction in ATR, the support-versus-resistance split, and how long ago. Wicks through and back count as holds, because that is a sweep. Leave the minimum-touches filter ticked.

Bar replay and split view

Bar replay (Ctrl+Alt+Shift+P, or F11 on the desktop) hides history after the bar you are on and gives it back one bar at a time with F9 — Shift+F9 steps back, F10 auto-advances — so you can practise reading a market forward without hindsight. Split view (Ctrl+Alt+Shift+S) shows a second tab's chart beside or below the active one; Ctrl+Alt+Shift+E moves the second pane to the next tab and Ctrl+Alt+Shift+O switches side-by-side versus stacked. Keyboard focus, speech and sonification stay with the active chart in both.

14. Volume Profile Navigation

A Volume Profile is a special type of indicator that shows the distribution of volume across price levels rather than across time. It appears as a horizontal bar chart layered on the price chart, showing which price levels saw the most trading activity.

When your focus is on a Volume Profile series, the Up and Down arrows change their behavior:

• Up Arrow: move to the next higher price bin in the volume distribution
• Down Arrow: move to the next lower price bin

Your screen reader announces the price level of each bin and the volume at that level.

Two special announcements to listen for:

• Point of Control (POC): the price bin with the highest volume. When you land on it, you hear a distinct square wave tone in addition to the normal audio. Your screen reader announces "Point of Control."
• Value Area: the range of price levels that account for approximately 70% of all trading volume. When you enter this range, your screen reader announces "Entering Value Area." When you leave, it announces "Exiting Value Area."

Left and Right arrows still work normally in Volume Profile navigation, moving the cursor through time.

15. Heatmap Overlay

Press Alt+H to toggle the volume heatmap overlay on the price chart. The heatmap shades each price candle and time zone based on relative volume intensity.

When the heatmap is active, playback audio incorporates the heatmap intensity of each bar — higher-volume bars play louder than lower-volume bars, giving you an auditory sense of where the market was most active.

Press Alt+H again to turn the heatmap off.

16. Settings and Customization

Saving Indicator Defaults

In any indicator's properties dialog (P or Shift+F12 while focused on the indicator), there is a "Save as Defaults" option. When you activate this, your current parameter and audio settings for that indicator type are saved. The next time you add an indicator of the same type, it will start with these saved settings.

Custom Audio Per Component

In the indicator properties dialog, the Sonification tab has an Acoustics section for the component you select. There you can set:

• Sound Patch: the voice this component plays — any built-in patch or any patch you built in the Sound Designer — with a ▶ button to preview it
• Green (bullish) / Red (bearish) patch: for directional components (candles, bars, histograms and volume bars), separate patches for up-bars and down-bars; plain lines and areas do not show these
• Waveform, noise, and volume: fallback controls that take over when no Sound Patch is chosen

Patches are live-linked: edit a patch in the Sound Designer and every component using it updates immediately.

Sound Designer (Alt+W)

The Sound Designer is a general-purpose patch workbench. A patch it produces can be assigned to event earcons here in the panel, or to indicator components through the properties dialog above.

A single patch can stack several oscillators via the "Add Oscillator" button. Each oscillator layer has:

• Waveform: sine, square, sawtooth, triangle, or noise
• Level: how much this layer contributes to the mix
• Freq Ratio: a harmonic multiple of the patch's base frequency (2.0 = one octave up)
• Noise Blend and Noise Colour: pink, white, or brown noise mixed into the layer

A Mix section sets the base frequency, a frequency multiplier, and overall volume; an Envelope section chooses a sustained tone or a plucked Ping and its duration. The Preview button auditions the whole patch, including its noise and envelope — not just the raw waveform. Patches saved by older versions still load unchanged.

17. Platform Support

Accessible Trader runs as a native desktop/mobile app (the "MAUI head" — Windows, Android, iOS, Mac) and as a self-hosted browser application (the "Linux web host"). The core keyboard navigation and audio model are the same everywhere. Platform-specific notes:

Windows:

• Works with NVDA, JAWS, and Narrator
• Full hardware keyboard required for all shortcuts
• WASAPI audio engine for lowest latency

Android:

• Works with TalkBack
• All shortcuts available via physical keyboard if connected
• AudioTrack audio engine

iOS:

• Works with VoiceOver
• Keyboard shortcuts require a connected hardware keyboard; on-screen keyboard access is limited
• AVAudioEngine audio

Mac:

• Works with VoiceOver
• Full keyboard support with hardware keyboard
• AVAudioEngine audio

Linux (web host, runs in a browser such as Firefox):

• Works with Orca and other browser-compatible screen readers
• Modifier remap: browsers (especially Firefox) reserve several Ctrl+Shift+<letter> chords at the browser-chrome level — Ctrl+Shift+T (reopen tab), Ctrl+Shift+H (history), Ctrl+Shift+P (private window), Ctrl+Shift+J (console), Ctrl+Shift+R (reload), Ctrl+Shift+W (close window) — and the page cannot override them. So on the web host every Ctrl+Shift+<letter> chord is remapped to Alt+Shift+<letter>. This affects all drawing tools and the detailed point summary (Ctrl+Shift+D → Alt+Shift+D). The letter and the command are unchanged — only the modifier differs.
• Chords with three modifiers (Ctrl+Alt+Shift+..., e.g. AI Analyst, narration, journal, save/load workspace) are not remapped — browsers don't reserve them.
• A few single-Ctrl browser chords are reserved at the chrome level and can't be overridden in-page, so on the web the in-app action moves to a web-safe chord (the reserved one is dropped from the Help dialog): new tab is Alt+Shift+N or the always-visible tab bar + button (not Ctrl+T); close a tab with its × button or by focusing the bar and pressing Delete (not Ctrl+W); switch tabs by pressing Ctrl+Alt+Shift+T to focus the tab switcher bar, then the arrow keys / Home/End / the number row (1–9) / Insert to add / Delete to close (not Ctrl+Tab); and jump between indicator sub-panes with Alt+PageUp / Alt+PageDown (not Ctrl+PageUp/Ctrl+PageDown, which the browser uses to cycle its own tabs).
• The Help dialog (F1) and its live shortcut table always read the bindings actually in effect on your host, so you will always see the correct modifier for the platform you are using.

Bar Replay and Split View

On the web host use Ctrl+Alt+Shift+P rather than F11 — browsers own F11 for fullscreen.

Tabs and Workspaces

By default only the chart on screen is live. To keep the other tabs watched too, enable Monitor background tabs in Settings (F12), General (desktop builds). Their symbol-scoped alerts and running strategies then keep evaluating on a polling cadence while you work elsewhere — announcements arrive prefixed with the symbol ("BTC/USD: crossed above 50,000"), background strategy signals are announce-only (never auto-placed orders), and the sonification/playback soundscape always belongs to the focused chart only. Press Ctrl+Alt+Shift+M for a spoken status of every watched tab.

Drawing Tools

On the Linux web host these Ctrl+Shift drawing chords are Alt+Shift — see Platform Support.

Panels and Dialogs

Quick Start Checklist

If you are opening Accessible Trader for the first time, here is a recommended sequence to orient yourself:

1. Press Shift+F1 to hear what symbol, provider, and timeframe is currently active.
2. Press Ctrl+Alt+Shift+C to get a full context summary.
3. Press Right Arrow a few times and listen to the pitch changes as price moves forward in time.
4. Press Space to start whole-chart playback and let the chart play for several seconds. Press Space again to stop.
5. Press Page Down to move to the first indicator pane, then press Down Arrow to step through its components.
6. Press F1 to open the help dialog and explore the full shortcut reference.
