Prop firm drawdown rules: trailing vs static

A static drawdown is a fixed floor (for example $90,000 on a $100,000 account). A trailing drawdown moves up with your highest balance, so giving back profit counts against you. We ran the same 20,000 simulated 30-day accounts through both: with daily swings of 1.5% of the account, the static 10% floor ended 8.8% of them and the trailing 10% floor 16.9% - about twice as many.

The four kinds of floor

Firms also differ on balance (closed trades only) versus equity (open losses count). Equity-based floors can be hit by a trade that later recovers.

How named firms set it (rule pages read 5 November 2026)

In the plans we read, futures firms mostly used end-of-day trailing floors and forex/CFD firms mostly static ones.

Why trailing ends more accounts

With a static floor, every dollar of profit adds room. With a trailing floor, room never grows above the limit, and a normal pullback after a good run uses it up. In our test the gap widened as daily swings got bigger: at 1% swings the two floors were close; at 1.5% the trailing floor ended about twice as many accounts. A floor that locks at the start balance helped only a little inside 30 days, because most accounts never got far enough ahead for the lock to matter.

How the test was run

Simulated accounts, not real traders: $100,000 start, 30 trading days, daily results drawn at random with a small positive average (one-tenth of the daily swing), a 5% daily loss limit and a 10% floor. Same random days for every rule, so only the rule differs. Real trading has streaks and fat tails, so real breach rates are likely higher than these; the comparison between rules is the point.

Questions

What is a trailing drawdown in a prop firm?
A loss floor that rises with your highest balance (or equity). If the limit is $2,000 and you reach $52,000 on a $50,000 account, the floor moves from $48,000 to $50,000.
Is end-of-day trailing better than intraday trailing?
Usually easier: intraday peaks you give back before the close do not raise an end-of-day floor. It still trails your best closing balance.
Does the trailing drawdown ever stop?
On many plans it locks at the start balance, or after a first payout. Check the firm's rule page - in the plans we read, wording differed by plan.
Balance or equity drawdown - what's the difference?
Balance counts only closed trades; equity also counts open losses. An equity rule can end an account during a trade that would have recovered.
