@efixdata/connector-ccxt

Universal multi-exchange data adapter for @efixdata/exeria-chart powered by CCXT.

Features

• One adapter for 100+ cryptocurrency exchanges via CCXT
• Historical OHLCV through fetchOHLCV
• Live price updates via REST polling (fetchTicker)
• Symbol normalization (BTCUSDT, BTC-USDT, BTC/USDT)
• Optional API keys for private endpoints

When to use CCXT vs dedicated adapters

| Use CCXT | Use dedicated adapter (adapter-binance, adapter-bybit, …) | | --- | --- | | You need many exchanges quickly | You ship one exchange in production | | Backend / Node.js integration | Browser live demo with WebSocket | | Prototyping and research | Smallest bundle and lowest latency |

Installation

npm install @efixdata/connector-ccxt

Requires a peer dependency on @efixdata/exeria-chart (or @efixdata/exeria-chart).

Quick start (Node.js)

import { createChart } from "@efixdata/exeria-chart";
import { CcxtAdapter } from "@efixdata/connector-ccxt";

const connector = new CcxtAdapter({ exchangeId: "kraken" });

const chart = createChart({
  container: "#chart",
  dataAdapter: connector,
});

chart.init();

await chart.loadData("BTCUSDT", {
  interval: "1h",
  limit: 500,
});

chart.subscribeToUpdates("BTCUSDT", (tick) => {
  console.log(tick.price ?? tick.c);
});

Configuration

const connector = new CcxtAdapter({
  exchangeId: "binance",
  apiKey: process.env.BINANCE_API_KEY,
  secret: process.env.BINANCE_API_SECRET,
  enableRateLimit: true,
  pollIntervalMs: 2000,
  sandbox: false,
});

Verified exchanges

These ids are tested in development:

• binance, bybit, okx, kraken, coinbase, kucoin, gate, bitfinex, mexc

Any exchange id supported by CCXT can be passed to exchangeId if it exists in the CCXT library.

Browser usage

Do not import CCXT directly in browser bundles for production charts. Most exchanges block cross-origin REST calls. Run CCXT on your server and proxy requests to the chart, or use a dedicated browser-friendly connector such as @efixdata/connector-binance.
