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. Six providers are available: Massive and Alpaca serve US equities; Binance, OKX, and Kraken serve crypto; CSV serves your own imported files. Equities prefer Massive, then Alpaca. Crypto resolves Binance → OKX → Kraken; CSV resolves last. 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).
• Kraken symbol — Kraken's native identifiers: a slash-separated spot pair (e.g. BTC/USD) and an exact perpetual id (e.g. PF_XBTUSD, where XBT is Kraken's code for Bitcoin). Used verbatim — Kraken instruments are searched and addressed exactly as Kraken names them.
• 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, OKX, and Kraken always stream in realtime from public endpoints. CSV datasets are static imports with no streaming at all.
• CSV dataset — your own OHLCV bars imported from CSV files (one file per timeframe, e.g. MES_1m.csv … MES_1w.csv), stored in the browser and charted under the CSV provider. See Importing CSV Data.
• 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.
