Trailing drawdown is a loss limit whose threshold rises with a qualifying account high. A later loss does not normally move that threshold back down. The important questions are which high counts, when the threshold updates, and whether it eventually stops trailing.

An end-of-day calculation does not mean losses are checked only at the close. Both Topstep's Maximum Loss Limit and Apex's EOD rules describe a floor that updates at the close but is enforced during the session.

The three numbers to separate

  • High-water mark: the highest account value that qualifies under the rule, such as the highest closing balance or highest intraday equity.
  • Loss floor: the threshold the account must stay above.
  • Remaining buffer: the account value used for enforcement minus that floor.

For a simple uncapped trailing rule:

New floor = the higher of the previous floor and the qualifying high minus the drawdown allowance.

Remaining buffer = current account equity minus the active floor.

Here, equity means the balance including open-position profit or loss. A firm's dashboard may use different labels. Lock levels, withdrawals, commissions and account resets can alter the calculation, so the formula is not a substitute for a particular account's rules.

Worked example: profitable overall, but at the loss floor

This is a hypothetical account, not an Apex, Topstep or MyFundedFutures plan. Assume a $50,000 starting balance, a $2,500 trailing allowance, no lock level, no withdrawals and balances already net of costs. Reaching the floor counts as a breach.

Event Account equity Qualifying high Active floor Remaining buffer
Start $50,000 $50,000 $47,500 $2,500
New high $52,000 $52,000 $49,500 $2,500
Another new high $55,000 $55,000 $52,500 $2,500
Loss after the high $53,200 $55,000 $52,500 $700
Floor reached $52,500 $55,000 $52,500 $0

The final account value is above the starting balance, but the account has reached its loss floor. Overall profit and compliance with a trailing limit are different measurements.

EOD versus intraday: calculation is not enforcement

With EOD trailing, a qualifying closing balance raises the floor for the next session. An intraday peak that disappears before the close does not itself raise that floor. With intraday equity trailing, open profit can raise the floor before a trade closes. Apex describes this distinction in its drawdown explanation.

Consider a second hypothetical account starting at $50,000 with a $2,000 allowance and an initial $48,000 floor. During the session, equity rises to $51,500, then falls to $50,300. Assume no lock level applies and no earlier breach occurred.

  • Intraday equity trailing: the peak raises the floor to $49,500. At $50,300 equity, the remaining buffer is $800.
  • EOD trailing: the floor remains $48,000 during that session, leaving $2,300 at the same equity. If the account closes at $50,300, the next floor becomes $48,300, leaving $2,000 immediately after that update.

EOD avoids raising the floor from the temporary peak in this example. It does not permit an account to cross the existing floor and recover later. Apex explicitly rules that out, while Topstep includes unrealized losses in real-time enforcement.

Does smooth growth create more drawdown room than one big day?

Not by itself. In the first hypothetical model, ten gains of $500 and one gain of $5,000 both take the account from $50,000 to $55,000. If both finish at the same qualifying high, neither reached a higher peak, and all other conditions are equal, both have a $52,500 floor and a $2,500 buffer.

A large gain does not automatically compress the buffer while the account remains at its high. The buffer shrinks when account value falls away from that high, or when a withdrawal reduces equity without reducing the floor. Once a floor locks, further gains can increase the buffer.

A separate consistency rule may treat the two profit patterns differently. That is not a property of trailing-drawdown arithmetic.

Firm names are not enough: identify the account

Topstep: Trading Combine and Express Funded Account

Topstep's MLL policy says the Trading Combine floor rises with end-of-day balance and locks at the starting balance. The Express Funded Account starts at a displayed balance of $0, not the headline account size. Its MLL also trails before locking at $0; the first payout sets the MLL to $0 even if it had not reached that level.

Do not describe every funded Topstep account as static from the outset. The policy treats the XFA separately and directs Live Funded Account readers to live-specific rules.

Apex: EOD, intraday and legacy are separate products

Apex's product-change notice identifies the pre-March 1, 2026 evaluation and Performance Account versions as legacy products. Existing legacy accounts keep their own rules. The newer EOD and intraday products must not be combined into a single statement that "Apex uses EOD drawdown."

Even within the EOD product documentation, the stop point differs. EOD Performance Accounts stop trailing at starting balance plus $100. Rithmic and WealthCharts EOD evaluations stop when the threshold reaches the target-profit balance; Tradovate EOD evaluations continue trailing. Account phase and connection both matter.

MyFundedFutures: Rapid is not the same as Rapid EOD

The Rapid 50K guide specifies EOD loss limits in evaluation and intraday equity trailing in the sim-funded stage. The separately documented Rapid EOD 50K uses EOD trailing in its sim-funded stage too. Those names describe materially different rules, not interchangeable versions of one account.

What to check before comparing accounts

Read the exact product's rules for:

  1. Evaluation, sim-funded or live phase, and any legacy purchase-date conditions.
  2. Balance versus equity, including how open profit and loss count.
  3. Calculation time, time zone and intraday breach test.
  4. The floor's lock level and the effect of a payout.
  5. Separate daily loss, consistency, contract-size and inactivity rules.

An automatic liquidation threshold is not a promised exit price. Topstep's execution guidance explains that stop-market orders become market orders and that slippage can change the final fill.

Frequently Asked Questions

Is static drawdown always better?

A static floor does not rise with new highs, but that alone does not establish which account is preferable. The starting allowance, daily limit, withdrawal rules and other restrictions still matter. "Static" is a calculation method, not a quality rating.

Can a withdrawal reduce the buffer after the floor locks?

Yes. In a hypothetical account with a fixed $0 floor and $4,000 balance, a $1,000 withdrawal leaves $3,000 of buffer. This is arithmetic only, not a statement that any provider would approve that withdrawal.

Does EOD mean I can wait until the close to recover a loss?

No for the Topstep MLL and Apex EOD accounts discussed above. Both enforce the active floor intraday. The EOD label describes when it moves, not a grace period after a breach.
