WASM

The WebAssembly build runs the same Rust core in the browser or any WASM runtime. Construct an Impact from a JSON spec and drive it with command(json) -> json.

npm install wickra-impact-wasm

import init, { Impact } from 'wickra-impact-wasm'

await init() // fetches and instantiates the .wasm module

const spec = JSON.stringify({
  strategy: { spec_version: 1, symbol: 'IMPACT', timeframe: '1h', indicators: {},
    entry: { ge: [{ price: 'close' }, 0] }, exit: { in_position: true },
    sizing: { type: 'fixed_qty', qty: 10.0 },
    execution: { order_type: 'market', fill_timing: 'next_open' } },
  book_model: { kind: 'orderbook_walk' }, participation_cap: 1.0, latency_ms: 0,
})

const impact = new Impact(spec)
const data = { IMPACT: [{ time: 0, open: 100, high: 101, low: 99, close: 100, volume: 1000 }] }
const report = JSON.parse(impact.command(JSON.stringify({ cmd: 'run', data })))
console.log(report.stats)

A given request yields a report byte-identical to the native build. See the live demo for the Wickra core running in your browser.
