A static drawdown floor stays tied to a fixed reference. A trailing floor moves upward as a specified high-water mark rises. The timing of that update and the treatment of open profit and loss can matter as much as the headline percentage.
Before buying a prop firm challenge, identify the exact product and stage you are comparing. A provider can use different rules for evaluation and subsequent accounts. The examples below are hypothetical calculations, not instructions for how much to risk.
Balance, equity and the breach floor
Balance normally reflects closed trading results. Equity also incorporates open profit and loss and relevant trading costs according to the provider’s calculation. The breach floor is the threshold at which the account violates its loss rule. Providers may use different terminology, so verify the definition in the agreement.
Suppose an account shows a balance of $50,000 and an open loss of $1,700 before other costs. Equity would be $48,300 in this simplified example. A dashboard displaying the balance alone could conceal how close equity is to a $48,000 floor. A later recovery does not necessarily undo a breach that already occurred.
Static drawdown: a fixed reference
In a simple static model, a hypothetical $50,000 starting balance and a $2,000 maximum loss allowance create a $48,000 floor. A rise to $51,000 does not move that floor under this model. The distance to it becomes $3,000, before other applicable limits and costs.
This does not mean every static programme handles withdrawals, resets or account transitions identically. A daily loss rule may still be breached even when the overall floor is respected.
Trailing drawdown: a moving reference
In a simplified uncapped trailing model, the floor equals the qualifying high-water mark minus a fixed $2,000 allowance. If that reference rises from $50,000 to $51,000, the floor rises from $48,000 to $49,000. If the balance then falls to $50,000, the floor does not move back down in this example.
| Stage | Account balance | Static floor | Trailing floor |
|---|---|---|---|
| Start | $50,000 | $48,000 | $48,000 |
| New qualifying high | $51,000 | $48,000 | $49,000 |
| Later loss | $50,000 | $48,000 | $49,000 |
The table assumes a balance-based reference with no cap, reset or withdrawal. It does not describe every provider. Some models stop trailing at a specified level; others have programme-specific adjustments.
End-of-day and intraday trailing are different
An end-of-day trailing rule may update its reference after the trading day closes. An intraday model may update it while positions remain open. In the latter case, an unrealised profit can potentially raise the floor before that profit is secured, depending on the rules.
Consider a hypothetical account that reaches $51,500 in equity during a trade, then closes the day at $50,500. A $2,000 trailing allowance based on the intraday equity peak would imply a $49,500 floor. A model based only on the closing balance would imply $48,500 after that close. The $1,000 difference comes from the reference point, not from a different advertised account size.
Daily loss limits are a separate test
A daily limit can reset at a specified server time and include open positions, commissions or swaps. Check the time zone and daylight-saving treatment. A position kept across a reset can face a different daily calculation even if no new trade is opened.
FTMO’s current Trading Objectives explicitly distinguish its product rules and describe the equity calculation used for its loss tests. Topstep’s Maximum Loss Limit documentation explains its end-of-day trailing mechanism and the treatment of its different account stages. Read the product-specific section rather than transferring one programme’s number to another.
A payout can change the remaining buffer
A withdrawal can reduce the balance while a loss floor stays fixed or is reset under a separate rule. The result can be less remaining room than the headline account size suggests. Before requesting a payout, work out the post-withdrawal balance and the resulting floor using the provider’s current policy.
For a hypothetical account with a $5,000 balance above its reference and a fixed floor of $0, removing $3,000 leaves a $2,000 balance above that floor. This is arithmetic only; it does not imply that a provider allows such a payout or that the remaining buffer is appropriate.
Questions to answer before choosing a programme
- What is the exact reference: initial balance, end-of-day balance or intraday equity?
- When does the floor update, and can it stop trailing?
- Do commissions, swaps and unrealised losses count?
- Does touching the floor cause a breach, or must equity fall below it?
- How do payouts, resets and moving to the next stage affect the floor?
- Is there another daily, consistency or position-size rule?
Frequently asked questions
Does end-of-day trailing mean losses are checked only at the end of the day?
No. The floor may update at the end of the day while compliance is monitored during trading. Check both the update schedule and the breach test.
Is static drawdown always better?
There is no universal best model. Compare the complete agreement, costs, payout rules and permitted trading style rather than selecting on one label.
Can two accounts with the same advertised size have different loss allowances?
Yes. Advertised size does not define the drawdown allowance. Calculate the actual floor and the available distance to it for each programme.
