WASM

A wasm-bindgen build that runs a full backtest in the browser — no backend, no upload. The same run signature and byte-identical reports as the native bindings.

npm install wickra-backtest-wasm

import init, { run } from 'wickra-backtest-wasm'

await init()

const spec = JSON.stringify({
  symbol: 'BTCUSDT', timeframe: '1h',
  indicators: { fast: { type: 'Ema', params: [12] }, slow: { type: 'Ema', params: [26] } },
  entry: { cross_above: ['fast', 'slow'] },
  exit:  { cross_below: ['fast', 'slow'] },
  sizing: { type: 'fixed_fraction', fraction: 0.95 },
})

const report = JSON.parse(run(open, high, low, close, volume, time, spec, 10_000))
console.log(report.metrics)

For microstructure strategies, run_json(requestJson) takes one request bundle.
