Trailing drawdown calculator
Enter your results day by day and see where the floor sat after each one. Nothing is sent anywhere and nothing is stored — it computes in your browser.
One day per line, or separated by spaces or commas. Losses as -220 or (220).
Why a trailing floor is the rule people blow without noticing
A static drawdown is easy to hold in your head: the floor is set on day one and never moves, so you always know the number. A trailing drawdown moves the floor up behind you every time you make a new high. The allowance stays the same size; what changes is where it is measured from.
That is why traders blow accounts while still in profit. Run an account up, give some back, and the loss that ends it is measured from the peak you touched — not from where you started and not from where you are. The floor followed you up and did not follow you down.
Most firms stop the trail at some point. Where it stops is the difference between two accounts that look identical on paper, and it is the field this calculator is really asking you to pick a firm for.
Closing balance or intraday equity
The second thing firms differ on is what counts as a new high. Some measure the peak on closing balances, so an open position that runs up and gives it back never moves your floor. Others watch live equity, so it does — you can raise your own floor with profit you never booked.
This tool takes one number per day, which is a closing balance by construction. On a firm that trails live equity that makes the answer a best case, and it says so above the table rather than quietly presenting it as exact. The per-firm reading of both fields is on each firm's page in the rules directory.
The firms in this calculator
The rules behind each option are the same ones Edgekeeper evaluates a live account against — one definition, used by the calculator, the dashboard and the warning on the trade form. Firms revise their terms, so each firm's page carries the date its rules were last checked and a link to their own.
