Static vs EOD vs Intraday Trailing Drawdown: A Source-First Guide

A static drawdown floor stays fixed. An end-of-day (EOD) trailing floor can move after a session closes. An intraday trailing floor can move while the session is still open as its reference value reaches a new high.

That is the useful short answer—but it is not enough to operate an account safely. Update timing and breach enforcement are separate questions. A firm can recalculate a floor only after the close while still checking that floor against real-time equity during the next session. Program, account stage, reference value, lock point and treatment of unrealized P&L can all change the result.

This guide explains the mechanics using hypothetical numbers. It is not a statement of any firm's current terms. Always verify the rule in your provider's official dashboard and agreement before trading.

Start with the floor, not the label

A drawdown rule usually defines a lowest permitted account value. In this guide, that value is called the floor. The distance between the account value used by the rule and that floor is the remaining buffer.

Before comparing labels, write down five fields:

• Starting reference: the balance or equity value from which the first floor is calculated.
• Drawdown distance: the fixed amount or percentage subtracted from the relevant high-water mark.
• Reference value: closed balance, realized balance, real-time equity, or another provider-defined value.
• Update timing: never, once after the trading day, or continuously intraday.
• Breach test: the balance or equity value compared with the floor, and when that comparison is enforced.

Two accounts can both be advertised as “EOD trailing” while differing on lock points, session cutoffs, open P&L, fees or what happens after a payout. The name is a starting point, not the complete rule.

Static drawdown: the floor does not trail

A static floor is established from the account's starting reference and does not move upward when the account reaches a new high.

With a hypothetical starting reference of $50,000 and a $2,000 static drawdown distance:

• Initial floor: $50,000 minus $2,000 = $48,000.
• If the account later reaches $51,200, the floor remains $48,000.
• If the account then falls, the original floor still applies unless another rule changes it.

Static does not mean that every other risk limit is fixed or absent. A program may still apply a separate daily-loss limit, position limit or other real-time control. Record those separately instead of treating “static drawdown” as the whole risk contract.

End-of-day trailing drawdown: the floor ratchets after a close

An EOD trailing floor generally uses a completed session value rather than every intraday peak. A simplified formula is:

new floor = maximum of the prior floor and the verified EOD high-water mark minus the drawdown distance

Using the same hypothetical $50,000 starting reference and $2,000 distance:

• Initial floor: $48,000.
• Intraday equity reaches $51,200, but the account closes at $50,500.
• If the rule trails the closing balance, the next floor becomes $50,500 minus $2,000 = $48,500.

The intraday peak did not set the new floor in this example. That does not automatically mean open equity is irrelevant to enforcement.

For example, Topstep's current Maximum Loss Limit documentation says its limit rises with end-of-day balance and never moves down, while also stating that hitting the current limit during the trading day—including through unrealized P&L—can trigger liquidation. MyFundedFutures' current Builder documentation describes an EOD floor that does not move intraday and adjusts after the session closes, with its own treatment of open-equity losses and a provider-specific lock point.

Those are different dimensions:

• When does the floor move?
• What live account value can hit the current floor?

Your journal needs both answers.

Intraday trailing drawdown: a live high can move the floor

An intraday trailing floor can ratchet upward when the provider's real-time reference reaches a new high. A simplified version is:

new floor = maximum of the prior floor and the intraday reference high minus the drawdown distance

With the hypothetical $50,000 starting reference and $2,000 distance:

• Initial floor: $48,000.
• Intraday reference equity reaches $51,200.
• The floor becomes $51,200 minus $2,000 = $49,200.
• If equity later falls, the floor does not normally move back down.

Whether unrealized gains count toward the high matters. MyFundedFutures' current intraday documentation, for example, says its referenced intraday model uses peak balance including realized and unrealized gains and stops trailing at a stated cap. Another provider or account stage may define the reference differently.

The phrase “intraday trailing” therefore does not tell you everything. Verify whether the high is based on balance or equity, whether open P&L is included, how frequently it updates, and where the floor stops trailing.

The same trading path can produce three different floors

For the hypothetical path above, the simplified floors are:

• Static: $48,000.
• EOD trailing after a $50,500 close: $48,500.
• Intraday trailing after a $51,200 reference high: $49,200.

These numbers are educational examples, not current limits for a named program. They intentionally exclude commissions, fees, daily-loss rules, lock points, payouts, resets and provider-specific session boundaries.

The lesson is not that one model is always better. It is that the same price path can leave a different remaining buffer depending on what moves the floor.

Seven questions to verify in the official rules

Before you add a prop-firm rule to a journal or spreadsheet, answer these from the current official source:

1. Which exact program and account stage is this? Evaluation, simulated funded and live accounts may differ.
2. What starts the calculation? Nominal account size, actual balance, zero-based balance or another reference.
3. Is the distance an amount or percentage? Record the exact currency and rounding behavior.
4. What moves the floor? Closed balance, realized P&L, total equity or another high-water mark.
5. When can it move? Continuously, at a defined session close, or never.
6. What value is tested for a breach? Balance, equity including open P&L, or a provider dashboard field.
7. Where does trailing stop? Starting balance, starting balance plus a buffer, or another lock point—and what do payouts or fees change?

Save the source URL and the date you verified it. Re-check after a rule announcement, account transition, reset or payout. A preset copied months ago is not stronger evidence than the provider dashboard you can see now.

Keep daily loss and maximum drawdown separate

A daily-loss rule and a maximum-drawdown rule answer different questions. A daily limit usually constrains loss within a provider-defined day and may reset at a session boundary. A maximum-drawdown floor can persist and ratchet across days.

Do not subtract one from the other or collapse them into one “room left” number unless the official rule explicitly defines that relationship. Track each rule with its own reference, reset time, current floor and remaining buffer.

Turn the rule into a review record

A useful post-session record does not need to predict a breach. It should preserve what the trader believed the rule was and what evidence supported that belief.

For each reviewed session, record:

• provider, program and account stage;
• official source URL and verification date;
• drawdown model and distance;
• reference value used to move the floor;
• floor before and after the session;
• lowest remaining buffer observed from the provider dashboard;
• any rule change, payout, fee or account transition that can alter the calculation.

That creates an auditable review trail. It does not turn a third-party journal into the provider's compliance system.

Compare the mechanics with the free calculator

The Prop Firm Drawdown Buffer Calculator lets you compare static, end-of-day trailing and intraday trailing mechanics with editable, browser-local inputs. It is an educational estimate; no form data is uploaded and your firm's official dashboard remains the source of truth.
