Plan the stop. Understand the drawdown.

A stop-loss is one part of a pre-trade plan. Drawdown is a way to describe a decline from a prior account or equity high. Both are useful risk language, but neither turns an uncertain forex outcome into a promise.

01 / Before the trade

A stop-loss belongs in the pre-trade plan

A stop-loss is a planned instruction or level intended to limit a loss if price moves against the trade. It works best as part of a plan written before entry: what would invalidate the idea, where the planned exit sits, what position size is involved, and what the estimated loss would be.

The stop is not a signal to trade, and it is not a guarantee of an exact fill. A wider stop can mean more price-move exposure for the same position size. Moving a stop farther away after entry can also change the plan’s potential loss, so record what your own rules say before the market is moving quickly.

02 / The account picture

Drawdown starts at a prior high

Drawdown is a decline from a prior account or equity high to a later lower value. The high is sometimes called a high-water mark. For example, if an account or equity value reaches a hypothetical $10,000 and later falls to $9,000, the decline is $1,000, or 10% from that prior high.

A drawdown describes what happened relative to a previous high; it does not predict whether or when a value will recover. Ask which number is being measured—balance, equity, or another defined series—and keep the time period and calculation consistent. A single winning or losing trade is not evidence of future performance.

Hypothetical illustration — not a target

Prior hypothetical high: $10,000
Later hypothetical equity: $9,000
Decline from the prior high: $1,000 / 10%

This arithmetic only illustrates the term. It is not a forecast, risk limit, performance claim, or recommendation for any account.

03 / A simple planning sequence

Write down the downside before entry

State the trade idea

Write down the pair, direction, entry idea, and the condition that would show the idea is no longer valid.

Choose the exit before entry

A stop-loss is a planned loss-limiting exit. Place its level as part of the pre-trade plan, not as a last-minute reaction to a moving price.

Estimate the exposure

Combine stop distance, position size, pip or point value, and known costs. Check the broker’s current contract details and account-currency conversion.

Name the uncertainty

Consider what could make the actual exit or loss different from the estimate, then decide what your own written plan says to do.

A simple planning estimate can be written as price-move loss ≈ stop distance × pip or point value, then add relevant costs and an allowance for uncertainty. Confirm the actual calculation with the broker’s current specifications; do not treat a formula as a universal position-size rule.
