Installation

npm install --save fast-trading-api

Quick Start

import { FastTradingApi } from 'fast-trading-api';
import { ExchangeName } from 'fast-trading-api/dist/types/lib.types';

// Initialize the API with your credentials
const api = new FastTradingApi({
  accounts: [
    {
      id: 'main',
      exchange: ExchangeName.BYBIT,
      apiKey: 'XXX',
      apiSecret: 'XXX'
    }
  ]
});

api.on("log", (message) => console.log(message));
api.on("error", (error) => console.warn(error));

await api.start();

Architecture

The fast-trading-api library is designed with performance and flexibility in mind:

Multi-threaded Design

• Main Thread Protection: The architecture isolates complex operations from the main thread, ensuring the UI you are building remains responsive.
• Web Worker Powered: Each exchange instance launches a dedicated web worker, moving CPU-intensive tasks off the main thread.
• Parallel Processing: Data transformations, calculations, and network operations run in separate threads.

Exchange Management

• Dynamic Initialization: The FastTradingApi class automatically initializes appropriate exchange handlers based on your configured accounts.
• Multiple Account Support: A single exchange type can manage multiple accounts (e.g., multiple Bybit accounts with different API keys).
• Unified Interface: All exchanges expose the same methods, making it easy to work with multiple platforms.

Data Flow

This architecture allows for:

• Real-time data processing without blocking the UI
• Efficient handling of high-frequency trading operations
• Seamless connection to multiple exchanges and accounts simultaneously
