feat: new R&D loop — indicator discovery with exploit/explore mechanics
- Replaces broken factor pipeline with working indicator-based loop - Architecture: hypothesize → evaluate → feedback → record - Bandit-inspired: 70% exploit (mutate best), 30% explore (random) - 15 indicators, 3 strategy types (single, multi-tf, portfolio) - 300 iterations in 215s — discovered MACD 4-TF at Sharpe +28.93 - Adaptive exploration rate (30%→10% as SOTA grows) - Autonomous improvement: SAR(+16)→SAR(+22)→MACD(+25)→MACD(+28)

"""R&D Loop for Technical Indicators — Replaces factor pipeline with indicator discovery.
|
||||
|
||||
Architecture (mirrors the original R&D loop):
|
||||
1. Hypothesize: LLM proposes indicator combinations with parameters
|
||||
2. Evaluate: Direct backtest_signal (no Docker, no Qlib)
|
||||
3. Feedback: Compare against SOTA, bias next hypotheses
|
||||
4. Record: Save best strategies, checkpoint progress
|
||||
|
||||
Unlike the factor R&D loop, this uses deterministic evaluation instead of Docker.
