Prop Rules Check / independent guide
How to compare prop firm drawdown rules
A practical framework for comparing daily loss, maximum loss and trailing drawdown without confusing a headline percentage with the rule that actually ends an account.

Start with the measurement method
Start with the measurement method “Drawdown” is not one universal calculation. A firm may measure equity, balance, a fixed starting amount, or a high-water mark. It may also evaluate the rule intraday or only at a scheduled close. Write down the measurement basis before comparing percentages; two equal-looking limits can create very different operating constraints. Look for the exact terms used in the official rule page, agreement and dashboard. If the documents disagree, treat the conflict as unresolved and ask the provider for written clarification rather than filling the gap with an assumption.

Separate daily and overall limits
Separate daily and overall limits A daily loss limit normally resets on a stated schedule, while a maximum loss limit may remain active for the life of the account. Record the reset timezone, what is included in the calculation, and whether floating profit and loss, commissions, swaps or fees count. A daily limit that resets at a different time from your trading session can change how you plan risk. The useful comparison is not simply “which limit is larger?” It is “what event would breach each limit, and how much room remains after open positions and costs are included?”

Model the event that ends the account
Model the event that ends the account For a trailing rule, identify the reference point: starting balance, end-of-day high, intraday high, or another published level. Then test a small set of neutral scenarios: a winning trade followed by a pullback, several open positions at once, and a loss that crosses a reset boundary. These are educational examples, not a forecast of results. Also check whether the rule changes after a payout, phase transition or account upgrade. A comparison is only reliable when the account state and model are named alongside the percentage.

Record the source and effective date
Record the source and effective date Save the official URL, the product name, the account size, the model, the access date and any “effective from” date. A snapshot is evidence of what was published at that moment; it is not a guarantee that the provider will keep the same terms. Our rule pages separate sourced fields from editorial interpretation for that reason.
