Pine Script Runner

Register a CCXT exchange, run the script against it, render the result. run() takes the file, the run options, the exchange name, and the "as-of" date; toMarkdown takes a signal id, the plots, and the schema mapping plot names to column headers:

import { addExchangeSchema } from "backtest-kit";
import { singleshot, randomString } from "functools-kit";
import { run, File, toMarkdown } from "@backtest-kit/pinets";
import ccxt from "ccxt";

const SIGNAL_SCHEMA = { position: "Position", close: "Close", btcClose: "BTC Close" };

const getExchange = singleshot(async () => {
  const exchange = new ccxt.binance({ options: { defaultType: "spot", adjustForTimeDifference: true, recvWindow: 60000 }, enableRateLimit: true });
  await exchange.loadMarkets();
  return exchange;
});

addExchangeSchema({
  exchangeName: "ccxt-exchange",
  getCandles: async (symbol, interval, since, limit) => {
    const candles = await (await getExchange()).fetchOHLCV(symbol, interval, since.getTime(), limit);
    return candles.map(([timestamp, open, high, low, close, volume]) => ({ timestamp, open, high, low, close, volume }));
  },
});

const plots = await run(
  File.fromPath("test_request_security.pine", "./math"),
  { symbol: "ETHUSDT", timeframe: "15m", limit: 180 },
  "ccxt-exchange",
  new Date("2025-09-24T12:00:00.000Z"),
);

console.log(await toMarkdown(randomString(), plots, SIGNAL_SCHEMA));
Copy

Change symbol/timeframe/limit in the run() options, or drop a new .pine into ./math/ and point File.fromPath at it.

A trivial script that proves cross-symbol data flows: it charts the current symbol's close and pulls BTC's 1h close via request.security, with a flat Position plot. Every output uses display=display.data_window so the runner picks it up as a column.

//@version=5
indicator("test_request_security", overlay=false)

btcClose = request.security("BINANCE:BTCUSDT", "1h", close)  // higher-timeframe / cross-symbol

plot(close,    "Close",     display=display.data_window)
plot(btcClose, "BTC Close", display=display.data_window)
plot(0,        "Position",  display=display.data_window)     // flat — just verifying data flow
Copy

run() feeds the script candles from ccxt-exchange and resolves the request.security("BINANCE:BTCUSDT", …) call through that same exchange — so a multi-symbol Pine strategy needs no extra wiring.
