# Algo Forge

**Full refactor of SniperGold SMC Pro+** — 3-engine architecture + hybrid ML.

## Baseline (old project — reference, do not delete)

| Component | Status |
|---|---|
| `SniperGold_SMC_ProPlus_v4_4.mq5` | Calibrated 2-head ML; test AUC LONG **0.6270** / SHORT **0.6207** |
| `SniperGold_SMC_ProPlus_v4_5.mq5` | MTF structure + index cache (0 errors / 0 warnings) |
| `SniperGold_ML.mqh` | MLP 19→12→2 + Platt calibration (not reused in AlgoForge) |

## Target Architecture (3 Engines + ML)

| Engine | Function | Status |
|---|---|---|
| **Engine 1** | MTF bar collector + reusable index cache (closed-bar lock, chart-TF independent) | ✅ Complete (Phase 1, 2026-08-21) |
| **Engine 2** | 4 independent signal agents N/C/E/P (dynamic-weight fuzzy) + separate aggregator | ✅ Complete (Phase 2, 2026-08-21) |
| **Engine 3** | Display like the original 75466 code (reads Engine 1–2 output only) | ✅ Complete (Phase 3, 2026-08-21) |
| **ML** | LSTM + Regime-Switching (MSM/GARCH) in front of LSTM, ~20-year sample, separate engine; walk-forward + bootstrap CI + multi-seed; deploy only if it beats the baseline | ❌ **No-Go (Phase 4)**: 2-layer LSTM + regime LOST to the baseline (dAUC −0.0196/−0.0134); baseline MLP 0.627/0.621 REMAINS deployed |

Agent timeframe parameters: **HARDCODED** `AF_E2_TF_S1..S4` = **H4/M30/M15/M3** (N/C/E/P) — manual inputs `InpHtfS1..S4` **removed**; `InpDispTF` (Engine 3, default = chart) remains an input.
