Split Position Sizing: When a setup triggers, the algorithm automatically divides your total calculated quantity into two separate legs:
Dynamic 1:1 RR Scaling: TP1 is locked precisely at a 1:1 Risk-to-Reward ratio relative to your Stop Loss distance. Once hit, half the trade is closed and secured.
Breakeven Migration on TP1: The moment TP1 is achieved, the script instantly shifts the Stop Loss for the remaining 50% (TP2) to Breakeven + Lock-in Pips, turning the rest of the trade completely risk-free while it runs toward the full impulse high/low.
