Contract caps are a loss rule in disguise

Percentage-based forex challenges sometimes limit lots, and sometimes do not say. Futures combines almost always print a maximum position. Topstep’s parameters page, captured with the other help articles, allows 5 minis or 50 micros on the 50k, 10 or 100 on the 100k, and 15 or 150 on the 150k, and says micros and minis count at 10 to 1.

That ratio means 50 micros is the same position count as 5 minis, not an extra sleeve of risk beside them. Traders who add ‘a few micros’ on top of a full mini position are already through the cap if the page’s ratio is what the platform enforces.
