Topstep vs Phidias Propfirm: prop firm rules compared

On Topstep and Phidias Propfirm's Fundamental and Premium plans the drawdown trails at end of day: the floor is recalculated once, from the closing balance, so open profit given back during the session does not raise it — but equity touching the floor during the session still counts.
