1. Glossary

Definitions of terms used throughout these docs.

Chart and workspace

• Pane — a single chart within the workspace, with its own timeframe, series type, indicators, and drawings.
• Active pane — the focused pane (amber border) that most actions target. See Multi-Pane Layouts.
• Timeframe — the time span each bar covers (1M … 1W). See Symbols & Timeframes.
• Series type — how price is drawn (candles, bars, line, Heikin Ashi, …). See Chart Types & Volume.
• Candle info line — the status line showing the hovered bar's OHLC, change, and volume.
• Layout — the arrangement of panes; can be saved. See Saved Workspace Layouts.

Indicators

• Indicator / study — a technical calculation plotted on the chart.
• Overlay — an indicator drawn on the price pane (e.g. a moving average).
• Own-pane study — an indicator drawn in its own sub-pane (e.g. RSI).
• Chart pattern — an automatically detected price formation (flag, head-and-shoulders, …). See Chart Patterns.

Drawings

• Drawing anchor — a point that defines a drawing's geometry, such as a trend-line endpoint or a rectangle corner. Selected anchor handles can be dragged to reshape a drawing.
• Magnet — drawing-canvas snapping that places or readjusts drawing anchors on nearby bar open, high, low, or close values.
• Drawing template — a saved per-tool preset for applicable drawing style settings and, for tools with text, text settings.
• Toolbar category — a flyout group in the drawing toolbar (Lines & rays, Channels, Brushes, Shapes & ranges, Fibonacci, Pitchfork, Gann, Volume & positions, Text). See Drawing Tools.
• Ray / extended line — a trend line projected to the chart edge: a ray goes one way from its first anchor; an extended line goes both ways.
• Channel — a pair of boundary lines. Parallel channels share a slope (with an optional median), flat top/bottom uses a horizontal second boundary, and disjoint channels angle each line independently.
• Level set — the editable list of ratio, angle-ratio, grid-ratio, or Fibonacci-sequence members a Fibonacci, Gann, or pitchfork tool draws; each member has its own visibility and line style (color, opacity, width, style).
• Fibonacci extension — continuation levels (e.g. 1.618, 2.618) projected beyond a measured move and its retracement, as opposed to retracement levels drawn within the move.
• Pitchfork — a median line with parallel tines drawn from three pivots; variants (Andrews, Schiff, modified Schiff, inside) differ in where the median originates.
• Gann angle — a price-by-time ratio (e.g. 1×1, 2×1) drawn as a fan ray or grid line, relating units of price to units of time.
• Regression trend — a least-squares line fit to a price source over a bar range, with optional standard-deviation bands and a Pearson's R readout.
• Anchored VWAP — the cumulative volume-weighted average price computed from a chosen anchor bar forward.

Data

• Provider — the source of market data. Four providers are available: Massive and Alpaca serve US equities; Binance and OKX serve crypto. Equities prefer Massive, then Alpaca. Crypto resolves to Binance first, then OKX. See Data Providers Overview.
• instId — OKX's instrument identifier format: dash-separated BASE-QUOTE for spot pairs (e.g. BTC-USDT) and BASE-QUOTE-SWAP for perpetual swaps (e.g. BTC-USDT-SWAP). Distinct from Binance's concatenated form (BTCUSDT).
• Frontend / backend mode — whether provider requests run from the browser or through the app's server routes.
• Realtime / delayed — how fresh the streaming feed is (a Massive realtime/delayed plan, or Alpaca's IEX free vs. SIP paid feed). Binance and OKX always stream in realtime from public endpoints.
• Forming vs. confirmed bar — the current bar is forming until its interval closes, then confirmed.

Backtesting

• Strategy — authored code that places trades over historical bars. See Writing Strategies.
• Backtest — a run of a strategy against history producing trades, equity, and stats.
• Equity curve — cumulative account value over the test.
• Buy-and-hold — the benchmark of simply holding the instrument over the same period.
• Drawdown — a peak-to-trough decline in equity.
• Pyramiding — the maximum number of same-direction entries allowed.
• OCA / OCO — one-cancels-all order groups, used for brackets.
• Slippage — a modeled adverse adjustment to fill price.

AI assistant

• Read tool — an action the assistant uses to observe the chart; runs immediately.
• Write tool — a proposed change queued for your approval (Apply). See Applying AI Chart Actions.

Authoring

• Authoring engine — the shared compiler/runtime for custom indicators and strategies. Pine Script v6 is the default; a legacy TypeScript engine is also available. See Pine Script.
• next(ctx) — the per-bar hook in the legacy TypeScript engine that runs once for each bar, oldest to newest.
• Composition — consuming one indicator or data series from another indicator or a strategy. In Pine Script this is done via request.security and ta.* calls. See Writing Indicators.

Personalization

• Theme mode — light, dark, or auto.
• Palette — a named color scheme (e.g. Dracula). See Themes & Palettes.
• Watchlist — a saved group of symbols. See Watchlists Overview.
