The sizing rule
Four lines on top of P1 Master's nine rules.
- Cushioncushion = balance − trailing DD floor. The floor = min(peak closed balance − max DD, start balance) — it trails up while below the start balance, then locks.
- Risk per traderisk $ = fraction × cushion. Conservative 0.05, standard 0.10, aggressive 0.15.
- CapsAccount preset A: $1,250 trailing DD, 20-micro cap. Preset B: $4,500 trailing DD, 15-ES cap. Size never exceeds the cap regardless of cushion.
- Everything elseEntries, stops, exits, session, grade filter and the daily −2R stop are inherited unchanged from the parent method.

How to use it
- When: growing a funded account from a thin cushion — fixed-$ risk near a trailing floor can breach on one normal losing streak; fraction-of-cushion cannot (the book never blew an account in any preset).
- Which preset: standard 0.10 is the reference. Conservative 0.05 roughly halves drawdown for roughly a quarter of the net — the right trade when the floor is close. Aggressive 0.15 pays only on preset A.
- The price: compounding cuts both ways — the standard preset's max drawdown is ×2.6 the fixed-$ Master's. Judge it by the DD column, not the net column.
- Referee: p1_master_flexR.pine implements the same rule on TradingView; entries carry Master's verification, the sizing math is spot-checked but not per-trade gated.
