High Frequency Trading Framework with Machine/Deep Learning

In this project, we provide a framework/pipeline for high frequency trading using machine/deep learning techniques. More advanced feature engineering (with depth trade and quote data) and models (such as pre-trained models) can be applied in this framework.

Target

• Extract trading signals from level-II orderbook data
• Predict orderbook dynamics using machine learning and deep learning techniques

Data

The SGX FTSE CHINA A50 INDEX Futures (新加坡交易所FTSE中国A50指数期货) tick depth data are used.

Strategy Pipline

Orderbook Signals

We use limit orderbook data to develop trading signals, including Depth Ratio, Rise Ratio, and Orderbook Imbalance (OBI).

Price Series

Feature Engineering

Other potentially useful signals:

• volume imbalance signal
• trade imbalance signal
• technical indicators of bid and ask series (RSI, MACD...)
• WAP/WPR, weighted average price, VWAP, TWAP
• .....

Signal generating techniques:

• consider different weights on different level of orderbook data for a particular signal
• consider moving average with period n (hyperparameter)
• consider weighted average of signals, such as weighted average of trade imbalance and orderbook imbalance
• Lasso regression, genetic programming
• .....

Models

This project only provides a baseline. More advanced models are welcomed:

• CNN
• GRU/LSTM
• XGBoost, AdaBoost, GBDT, LightGBM
• Attention, Auto-encoder
• TabNet
• Pre-trained models
• .....

Performance Metrics

The performance metrics are subject to amendment, including the PnL calculation, commission fee consideration, etc.
