jgrusewski 0718dabd4c feat: GPU-native multi-timeframe features — 4 windows × 4 features
16 new features computed directly in the state_gather CUDA kernel
from market data already on GPU. No CPU feature engineering.

Lookback windows: 5, 15, 60, 240 bars (≈5min, 15min, 1hr, 4hr)
Features per window:
  - Return over N bars (directional bias)
  - Volatility (high-low range / close)
  - Volume trend (current / N-bar average)
  - Momentum (position within N-bar range [0=bottom, 1=top])

State dim: 66 raw (72 aligned) without OFI, 74 raw (80 aligned) with.
The model now sees price action at 4 timescales simultaneously.

ml

10-model ML ensemble for the Foxhunt HFT system, built on Candle v0.9.1.

Models

  • DQN (Rainbow) — deep Q-network with prioritized replay, dueling heads, noisy nets
  • PPO — proximal policy optimization with GAE, LSTM policies, clip-higher
  • TFT — temporal fusion transformer for multi-horizon forecasting
  • Mamba2 — state space model for sequence prediction
  • Liquid Networks — biologically inspired networks for non-stationary data
  • TLOB — transformer-based limit order book analysis
  • KAN — Kolmogorov-Arnold networks
  • xLSTM — extended LSTM architecture
  • TGGN — temporal graph neural network
  • Diffusion — diffusion-based generative model

Key Modules

  • ensemble — model ensemble coordination and confidence aggregation
  • hyperopt — PSO-based hyperparameter optimization with per-model adapters
  • trainers — unified training loops (DQN, PPO, supervised)
  • inferenceInferenceAdapter trait for prediction
  • checkpoint — model checkpointing and restoration
  • evaluation — walk-forward evaluation pipeline
