Downloaded M5 data via Dukascopy for GBP_JPY, GBP_USD, EUR_USD, USD_JPY
(~200k bars each, 2021-2024). Added M5 to validate_and_split pipeline.
Tested S12 (Asian Range Sweep), S15 (Momentum Continuation), S16 (London
ORB) with M5-scaled parameters. No viable edge found — best result was
S16_GBP_JPY OOS PF=1.03 but IS was negative (PF=0.71).

S8_OB: UP (0.66->1.59). Three of four strategies show improving edge.

Implemented two M15 intraday strategies to diversify the portfolio:
- S10: VWAP mean reversion in ranging markets (ADX<30, RSI(9) extremes)
- S11: ADX trend pullback to 20 EMA in strong trends (ADX>30, rising)
Added rsi_9 and atr_10 to the indicator pipeline for both strategies.
Backtested on IS (2021-2022) and OOS (2023): both strategies produced
insufficient trade counts on M15 and failed generalization. S10 best
result was EUR_GBP at Gen 0.65 (WARN). S11 collapsed to 0% WR OOS
across all param sweep combos. Both dropped from active portfolio —
3-strategy core (S7_Tight, S9_Filtered, S3) remains unchanged.

S7: add RSI floor (RSI<40 = 0% WR) and ATR percentile cap (high-vol
regime = worse RR). IS flips from PF 0.68 to 1.52, OOS holds at 1.80.
S3: add confluence gate (C>=4) and skip hours 09-10 (0% WR). IS PF
1.06 -> 1.22, OOS PF 1.07 -> 1.23.
S9_Filtered: add skip_monday (unreliable Asian ranges after weekend
gaps). IS PF 1.10 -> 1.31, OOS holds strong at 2.26.
Drop S9/GBP_USD (negative PF across all param combos) and S4F/EUR_AUD
(overfit: IS 1.43 collapses to OOS 0.48). 3-strategy portfolio: all
PASS generalization, IS PF 1.29, OOS PF 1.55, Gen 1.46.

Externalize hardcoded params in S4F (5 params) and S3 (9 params) as class
attributes for sweep compatibility. Add unified backtest runner with IS/OOS
validation and generalization scores, plus parameter grid sweep (90 combos)
with OOS validation. S7/S9/S9_Filtered pass generalization; S4F/S3 confirm
defaults are near-optimal.
