How it works
Each plan's rules are entered from the firm's own pages: the daily loss limit (what percentage, of what, measured from which start-of-day value, and whether touching it fails the account) and the max drawdown (static, trailing, or end-of-day trailing, and whether it stops trailing at the starting balance). The floors are worked out from your account's figures, and the loss at your stop is converted to your account currency. The methodology has the details and the cautious choices we make.
