Prime drawdown: the Max Loss Limit

Your Max Loss Limit is the single hard limit on a Prime account. Hitting it closes the account immediately. The same model applies in the evaluation and once you're funded.

Prime also has a daily loss limit, but that's a soft guardrail. The Max Loss Limit is the one that ends accounts.

Your Max Loss Limit by size

It's measured end-of-day

Your Max Loss Limit trails your highest closing balance — never an intraday high.

That's an important distinction. A rough patch mid-session can't end your account on its own; only where you finish the day counts. The limit follows your account up on every day you close higher, and intraday spikes never move it.

It locks in your gains

Once your account climbs past its initial trail balance, the Max Loss Limit permanently locks at your starting balance + $100 and never moves again.

From that point on, the profit you've earned is protected — the limit can't climb toward your balance and squeeze you out of a winning account.

How the two phases differ

• In the evaluation the limit simply trails your closing balance as you work toward your target. There's no lock involved — just room to trade until you pass or fail.
• Once funded it trails the same way, then locks at your starting balance + $100 as your balance grows, and never falls back.

Why this matters on Prime

Because the Max Loss Limit trails your closing balance and then locks, Prime rewards steady growth and protects the progress you've made. The daily loss limit sits on top of it as a per-session guardrail — so on Prime you have a limit on how bad one day can get, and a limit on how far the account can fall overall.

The locked balance is also the figure your payouts are measured against — your profit has to clear it before you can withdraw. See Prime payouts.
