API Documentation & Guides

Write custom technical indicators, build signals, trigger automated alerts, and paint directly on the charting canvas using client-side JavaScript. No compilation delays, full ES2020 features, and pixel-perfect 2D rendering wrappers.

Get started Launch Script Editor

BacktestX Script Engine

const bars = ctx.bars;
const bounds = ctx.bounds;
const ema200 = ctx.ema(bars.map(b => b.close), 200);

// Custom canvas drawing logic
ctx.beginPath();
ctx.strokeStyle = '#ff3366';
ctx.lineWidth = 2.5;
ctx.moveTo(ctx.barToX(bounds.startIndex), ctx.priceToY(ema200[bounds.startIndex]));

Built-In Indicator Helpers

const rsiVal = ctx.rsi(closeArray, 14);
const macd = ctx.macd(closeArray, 12, 26, 9);
const atrVal = ctx.atr(bars, 14);
const bands = ctx.bollingerBands(closeArray);
