Node.js Code for Bar Trading

Below is the Node.js code for automating bar trading using E-Trade API.

const axios = require('axios');
const moment = require('moment');

// Replace with your E-Trade API credentials
const CONSUMER_KEY = "your_consumer_key";
const CONSUMER_SECRET = "your_consumer_secret";
const ACCESS_TOKEN = "your_access_token";
const ACCESS_TOKEN_SECRET = "your_access_secret";

const BASE_URL = "https://api.etrade.com/v1";  // Use sandbox URL for testing

// Define your stock and expiration logic
const STOCK_SYMBOL = "VIDEO";  // Replace with actual symbol
const CONTRACT_EXPIRATION = moment().add(7, 'days');  // 1-week expiration

// Function to get market open time
function getMarketOpen() {
    return moment().hour(9).minute(30).second(0).millisecond(0);
}

// Function to get market close time
function getMarketClose() {
    return moment().hour(16).minute(0).second(0).millisecond(0);
}

// Function to place a market buy order
async function buyStock() {
    const url = `${BASE_URL}/accounts/${STOCK_SYMBOL}/orders/place`;
    const data = {
        symbol: STOCK_SYMBOL,
        orderType: "MARKET",
        priceType: "MARKET",
        quantity: 1,
        orderAction: "BUY"
    };
    const response = await axios.post(url, data, { headers: { Authorization: `Bearer ${ACCESS_TOKEN}` } });
    return response.data;
}

// Function to place a market sell order
async function sellStock() {
    const url = `${BASE_URL}/accounts/${STOCK_SYMBOL}/orders/place`;
    const data = {
        symbol: STOCK_SYMBOL,
        orderType: "MARKET",
        priceType: "MARKET",
        quantity: 1,
        orderAction: "SELL"
    };
    const response = await axios.post(url, data, { headers: { Authorization: `Bearer ${ACCESS_TOKEN}` } });
    return response.data;
}

// Trading Logic
async function executeBarTrading() {
    const today = moment().day();  // 0 = Sunday, 1 = Monday, ..., 5 = Friday
    const currentTime = moment();

    if (today === 1 && currentTime.isSameOrAfter(getMarketOpen())) {
        console.log("Buying stock at market open...");
        const buyResponse = await buyStock();
        console.log(buyResponse);
    }

    while (moment().isBefore(CONTRACT_EXPIRATION)) {
        await new Promise(resolve => setTimeout(resolve, 60000));  // Check every minute
        if (moment().day() === 5 && moment().isSameOrAfter(getMarketClose())) {
            console.log("Selling stock at market close...");
            const sellResponse = await sellStock();
            console.log(sellResponse);
            break;
        }
    }
}

// Run the trading function
executeBarTrading();
