jgrusewski 809ee287d8 fix: trailing stop order-of-operations + b2_size guards
- Move trailing stop BEFORE execute_trade in training kernel (was after,
  then undone). Now matches backtest: check → modify target → execute.
  Eliminates the wasteful execute-then-undo pattern.
- Trailing stop uses current-bar unrealized (not raw_next forward-looking)
  for train/eval consistency
- Add b2_size/b1_size guards to action re-encoding in both kernels
  (prevents division by zero if branch sizes are ever 0)

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

Usage
