Trailing Drawdown

Context & Mechanics

How it works

The trailing drawdown is the stricter variant of the overall loss limit at a prop firm: the loss floor sits at a fixed distance below the highest account balance ever reached – not below the starting capital. On a nominal $100,000 account at 10 %, the floor starts at $90,000. If equity rises to $105,000, the floor ratchets up to $95,000. If equity falls afterwards, the floor stays put – it never comes back down.

Variants by provider

Three details determine how harsh the rule is. First, the measurement basis: some providers trail on equity highs including open positions (intraday), others only on the daily closing balance (end of day). The intraday variant is considerably stricter because even a temporary high in an open trade lifts the floor. Second, the distance: historically 5–10 %. Third, freezing: many providers stop the trailing once the floor reaches the starting capital (breakeven freeze) – from then on the account behaves as if it had a static floor.

How it differs from a static drawdown

With a static drawdown the floor stays fixed below the starting capital; profits permanently enlarge the usable buffer. With a trailing drawdown the buffer is constant: even a trader who has built $5,000 in profit may only ever lose the fixed distance from the peak. Together with the daily loss limit, the rule forms the risk corset of many one-step challenges and instant-funding models.

Why it matters for traders

The most common fallacy is calculating with "house money" after a winning streak – under a trailing drawdown that cushion does not exist. The intraday variant is especially treacherous: a trade that runs far into profit and then retraces can have lifted the floor and shrunk the buffer without any profit being realised. Practising a provider's trailing logic under realistic conditions avoids such surprises: the GlanWick simulator tracks a trailing drawdown in real time – GlanWick is a training and simulation tool and not a prop firm itself.

Execution Example

A trader runs a funded account of nominally $100,000 with a 10 % trailing drawdown (equity basis, trailed intraday, breakeven freeze at $100,000).

Start: equity $100,000, floor $90,000 (fixed distance $10,000).
A winning streak lifts equity to $105,000 → the floor ratchets up to $95,000.
A pullback to $97,000 → the floor stays at $95,000; only $2,000 of usable buffer remains even though the account sits +$5,000 above start – none of it realised.
A further loss of −$2,500 pushes equity to $94,500 → floor breached, account closed. With a static floor ($90,000) the account would still have been alive.

Execution Risk & Errors

Assuming profits permanently enlarge the buffer

Confusing intraday and end-of-day trailing

Letting open profits run far without knowing the interim high lifts the floor

Not knowing the provider's breakeven freeze

Increasing position size after a new equity high although the buffer stays the same

Frequently Asked

What is the difference between a trailing and a static drawdown?

With a static drawdown the loss floor stays fixed below the starting capital and profits enlarge the buffer. With a trailing drawdown the floor moves up with every equity high – the buffer stays constant.

Does an open trade lift the floor?

It depends on the provider. Intraday-trailed variants count every equity high including open positions; end-of-day variants only the daily closing balance. Check this definition before the challenge.

Does the trailing drawdown ever stop moving?

With many providers, yes: once the floor reaches the starting capital it freezes (breakeven freeze). From then on the account can only fail by losses below the starting capital.

Can I practise a trailing drawdown in advance?

Yes. The GlanWick simulator replicates a trailing drawdown with a configurable distance risk-free and tracks it in real time.
