Capital Efficiency

The Fat Pitch

The edge the average trader never had.
"All your trades are the same size. That's the mistake keeping you at zero."

Not every trade deserves the same size. The real jump in profitability isn't winning more often — it's putting more capital where the data justifies it, and less where it doesn't.

Real NQ 1-minute chart, Sep 15 2026: a tight stop at the POI and a far target, about 4.6R

1 What a fat pitch is

The trade where all three line up:

High grade × small stop × far target = the fat pitch. The trade that deserves the press.

2 The math that proves it

With a fixed dollar risk: profit = risk × R-multiple. The size of the stop disappears from the equation — the small stop already bought you more contracts for the same risk. Only two things move the outcome: the probability (the grade) and the R (target ÷ stop).

Example: an A+ with a 30-pt stop and a 150-pt target = 5R. Per dollar risked it returns ~2.6× more than the same A+ with an 80-pt stop (1.9R). That's why you size up on fat pitches — their return per dollar is the highest on the board.

3 The guardrail (non-negotiable)

Always with fixed risk as the floor. The press never exceeds your max. This is capital efficiency, not gambling: put the money where the data justifies it — not where patience allows it.

⚠ watch out Sizing up on a feeling, or on a big move you're afraid to miss. Size follows the data (grade × R), never emotion. A B-grade with a wide stop gets the minimum, no matter how exciting it looks.
The takeaway

Fixed risk is the floor; the fat pitch is where you press. High grade, tight stop, far target — that trade returns the most per dollar on the board, so it gets the size. Everything else gets the minimum.
