Why EdgeSizer

Built for the way
prop traders actually work.

Every other calculator makes you do the bracket math yourself. EdgeSizer goes from your entry and stop all the way to exact OCO dollar amounts.

Auto OCO Brackets
Exact dollar amounts for Stop Loss and Take Profit in each bracket. Ready to paste into your platform.
Smart 3-TP Split
Front-heavy allocation: more contracts at TP1 to lock profits, smaller runner at TP3. Auto-calculated.

Indices, metals, energy, and currencies. Mini and micro contracts. Every spec from CME Group directly.
No Account Needed
