    let markets = await binance.loadMarkets();
    console.log(markets);

Fetching Ticker Data

    let binance = new ccxt.binance();
    let ticker = await binance.fetchTicker('BTC/USDT');
    console.log(ticker);

Placing an Order

(async () => {
    let binance = new ccxt.binance({
        apiKey: 'YOUR_API_KEY',
        secret: 'YOUR_SECRET_KEY'
    });
    let order = await binance.createLimitBuyOrder('BTC/USDT', 1, 50000);
    console.log(order);
})();

Fetching Balance

const ccxt = require('ccxt');

(async () => {
    let binance = new ccxt.binance({
        apiKey: 'YOUR_API_KEY',
        secret: 'YOUR_SECRET_KEY'
    });
    let balance = await binance.fetchBalance();
    console.log(balance);
})();

Building a Simple Trading App with CCXT

const express = require('express');
const ccxt = require('ccxt');

const app = express();
const port = 3000;

app.get('/ticker/:pair', async (req, res) => {
    let binance = new ccxt.binance();
    let ticker = await binance.fetchTicker(req.params.pair);
    res.json(ticker);
});

app.listen(port, () => {
    console.log(`App running on http://localhost:${port}`);
});

In this example, we’ve set up a simple Express.js server that fetches the latest ticker data for a given trading pair.
