P1 Fast Flex sizing overlay · sim

P1 Fast trades with flexible-R sizing — the automated LucidPro-style eval configuration. Same M1be trade sequence as P1 Fast; per-trade size follows the cushion. This is the configuration running the automated eval pipeline.

Honesty note: flexR books are a money-management overlay on the stored engine book — idealized fractional sizing, one path, in-sample. They share every caveat of the engine book (touch fills, zero net slippage) and add their own. Treat shapes, not dollars, as the signal.

The sizing rule

Identical cushion-fraction rule as Master Flex, applied to the Fast book — plus the live-eval taper.

  1. 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.
  2. Risk per traderisk $ = fraction × cushion. Conservative 0.05, standard 0.10, aggressive 0.15.
  3. 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.
  4. Everything elseEntries, stops, exits, session, grade filter and the daily −2R stop are inherited unchanged from the parent method.
  5. Live-eval taperNear the eval target, risk only what is still needed: contracts = min(size($800), ceil(needed ÷ (1.9 × risk-per-contract))). A +2R win still finishes the eval; a loss costs less; overshoot median falls $285 → $76.
  6. DesperadoIf remaining room is under $800, size at the full 20-micro cap — when a reset costs $90, a wounded account's downside is already fixed, so the upside is free.
