Round 4, 3 Oct 2026 night (Bangkok): 52 more ideas on top of rule v4.2, from Turtle (skip after winner, 55 day, pyramiding,
10 day exit), Clenow (100d filter, gap filter, regression ranking), Minervini (trend template, near highs), Weinstein (stage 2),
Faber (200d), equity curve trading (MA filter, drawdown throttle, loss streak sizing), crypto rotation order (BTC dominance,
large before small, late cycle memes, lead lag), breakeven / time / chandelier / super hot exits, slots, correlation, vol target.
Kept: BUY MORE (pyramid once at +15% above the buy, before extended), and SELL 75% instead of 50% at extended after adding.
 Book +1221% (dd -25) vs v4.2 +980% (dd -25); 2023 +169/+133, 2024 +160/+157, 2025 +20/+18, 2026 +56/+51.
 Neighbours: steps 10 to 15% all better in both halves; 20%+ no change. Adding but only selling 50% when extended: worse (2025 -6%).
 Not on young baskets (fast rule): no gain there.
