Code Explanation:

This program mimics a simplified high-frequency trading (HFT) system using Java, which is particularly popular in the finance industry for its robustness and decent performance.

• We start with a MarketDataHandler class that simulates incoming market data using a priceQueue. The onPriceTick method gets invoked to add new price points simulating live market updates.
• A TradingStrategy interface defines the blueprint for any trading strategies. Here, we’ve implemented a simple strategy SimpleThresholdStrategy that buys below a certain price and sells above another threshold.
• TradingEngine class implements Runnable and acts as the core of our HFT simulator. It connects market data with the trading strategy, and has a tradesQueue for executing trades.
• The trading logic runs in an infinite loop until the thread is interrupted, processing price data and executing trade decisions based on the strategy.
• Finally, in the HighFrequencyTrading class, we mimic the live market data feed by pushing random prices through dataHandler and start the trading engine in a separate thread.
• The trading decisions are saved in the tradesQueue and printed out to the console once the engine thread is safely shut down.

This sample code showcases the asynchronous nature of HFT systems, where market data processing and trading decision making happen in near real-time. It simplifies the complexities of a real-world system, such as networking, error handling, and much more sophisticated strategies and latency optimizations. It serves as a demonstration of an HFT system’s basic architecture.
