Prop Firm Daily Loss Calculator

The daily loss limit is the rule that ends most prop-firm challenges. This tool shows exactly how much buffer you have left today and what risk per trade lets you survive a losing streak without breaching.

Why the daily limit catches so many traders

Total drawdown limits fail slowly; daily limits fail in an afternoon. A 5% daily limit at 1% risk per trade sounds like five chances, but slippage, spread widening and revenge-sizing compress it fast - and some firms count floating losses against the limit too, so an open trade can breach it before it closes. Rules differ between firms and change over time, so verify how yours measures the limit (balance vs equity, static vs trailing) before relying on any calculation.

Frequently asked questions

Is the daily limit measured on balance or equity?

It varies by firm. Equity-based limits count open floating losses; balance-based limits only count closed trades. This changes everything about how much you can safely have open at once - check your firm's current rules.

What risk per trade do funded traders typically use?

Commonly well under 1% per trade, precisely because the daily limit punishes clusters of losses. The right number depends on your strategy's losing-streak profile - see the risk of ruin calculator.

Can an EA respect a daily loss limit automatically?

Some can. Nebula Pro and Ultimate let you set hard daily and total drawdown caps to match a prop-firm rule set, so strategies that would breach those limits are filtered out during evolution - though passing a challenge is never guaranteed. See Nebula for prop-firm traders.
