Every trade needs to answer one question: how many contracts?

LO1 answers it automatically. You set a daily loss limit (DLL) — the most you’re willing to lose in a day. LO1’s auto-sizer works backward from that number to figure out how many MYM contracts to trade, accounting for both your initial breakout trade and the recoup trade that fires if the breakout stops out.

You never need to calculate contract counts yourself.

LO1 also automatically determines the maximum affordable range — the widest breakout box it will trade based on your DLL. Wider ranges mean larger stops, and the recoup trade amplifies that risk through YM proxy rounding. The system caps the range so that a single trade set’s worst case (T1 stops out, then recoup stops out) stays within your DLL.
