Copmosite architecture

Algorithmic trading requires a flexible and scalable architecture for efficient strategy development, testing, and execution. A composite architecture using the Barfin platform, supplemented with a powerful Redis data bus, provides a solution that meets the demands of modern financial markets.

Advantages of the composite architecture

1. Modularity and separation of concerns

The composite architecture enables breaking down the trading system into microservices, each responsible for a specific area. Barfin facilitates strategy development and testing, while Redis handles data storage and ensures high performance.

2. Integration and interaction

The Redis data bus enables rapid and efficient interaction between microservices. It allows seamless data exchange between components of the trading system without delays.

3. Risk management and monitoring

A risk management service can be integrated with Barfin, and data can be stored and updated through Redis. This ensures efficient risk management and real-time monitoring of results.

TypeScript implementation

Here's a TypeScript code example demonstrating the composite architecture of a Barfin trading system with Redis:

import { Strategy, DataFeed, Bar } from 'barfin';
import Redis from 'redis';

// Connect to Redis
const redisClient = Redis.createClient();

// Define the strategy
class MyStrategy extends Strategy {
    // ... strategy implementation ...
}

// Initialize the data feed
const dataFeed = new DataFeed('AAPL', '2022-01-01', '2022-12-31');

// Initialize the strategy
const strategy = new MyStrategy();

// Attach the strategy to the data feed
dataFeed.addStrategy(strategy);

// Process bars and send data to Redis
dataFeed.on('bar', (bar: Bar) => {
    // ... process the bar ...
    redisClient.set('latest_bar', JSON.stringify(bar));
});

// Start the data feed
dataFeed.start();

// Retrieve data from Redis
redisClient.get('latest_bar', (err, reply) => {
    const latestBar = JSON.parse(reply);
    console.log('Latest bar:', latestBar);
});

The composite architecture of the Barfin trading system in TypeScript, using the Redis data bus, facilitates efficient interaction between microservices, data management, and high flexibility. This solution is suitable for creating a modern, scalable, and reliable trading system capable of tackling the challenges of contemporary financial markets.
