AI Models for Market Data

Training deep learning architectures against financial time-series to extract alpha signals, model regime shifts, and generate synthetic data for robust backtesting.

LSTM

Temporal Price Prediction

Long Short-Term Memory networks trained on OHLCV candlestick data with attention mechanisms. Captures temporal dependencies in price action for short-horizon forecasting. The model ingests 60-day lookback windows of normalised returns, volume profiles, and technical indicators, outputting a 5-day directional probability distribution.

Directional Accuracy 78.2%
TRANSFORMER

Market Regime Detection

Transformer-based encoder for classifying market regimes — trending, mean-reverting, high-volatility — using self-attention over multi-asset correlation matrices. Trained on rolling 252-day windows across 500+ equities, the model identifies structural breaks in market dynamics before traditional statistical tests.

Regime Classification F1 0.84
GAN

Synthetic Market Generation

Generative Adversarial Network producing realistic synthetic order book data for strategy backtesting. Preserves fat tails, volatility clustering, and microstructure patterns. The discriminator is trained to distinguish real L2 order book snapshots from generated ones, pushing the generator toward statistical fidelity.

Statistical Fidelity Score 0.71
RL

Reinforcement Learning Agent

PPO-based agent trained against simulated market environments with realistic slippage and transaction costs. Optimises Sharpe-adjusted returns over variable holding periods. The reward function penalises drawdowns asymmetrically, producing agents that are conservative in adverse regimes and aggressive in favourable ones.

Out-of-Sample Sharpe 1.65
