Drawdown is the fall in an account from a peak to a later low. If a £10,000 account reaches £11,000 and then slides to £9,350, the drawdown is measured from £11,000, not from the starting balance. That peak-to-trough figure is the number that quietly ends most accounts, because traders watch the latest trade and ignore the hole that has opened under the equity curve.
A losing trade is an event. Drawdown is a condition. Conditions last longer than people plan for.
Peak to Trough, Not “a Bad Day”
Suppose you trade GBP/USD through the London session and finish Monday up. Tuesday and Wednesday give back more than Monday made. Thursday looks fine on the calendar and still closes red. Friday you are not “unlucky this week”. You are in a drawdown from the Monday high.
The same pattern appears on the FTSE 100. A strong cash open can mark the peak. The next three sessions can grind lower without a single dramatic candle. The account still has a drawdown, even if no individual loss felt large.
Professionals treat that path as a risk statistic. Beginners treat it as a mood.
Why the Maths Is Unforgiving
Percentage losses and percentage recoveries are not symmetrical. The deeper the hole, the larger the subsequent gain needed just to stand still.
- 10% down needs about 11% back
- 20% down needs 25% back
- 30% down needs about 43% back
- 50% down needs 100% back
That is why a 50% drawdown is not a “setback”. It is a demand for a double, from a smaller base. Many accounts never get the double. They get larger trades aimed at getting even.
The number that ends the account is often not the crash. It is the attempt to repair the crash too quickly.
Daily Drawdown Versus Overall Drawdown
Overall drawdown is the peak-to-trough decline across days or weeks. Daily drawdown is how much you lose from the day’s starting equity, including open trades. A trader can be within a modest overall hole and still have a violent Tuesday if London and New York both go against an oversized GBP position.
Daily limits exist to stop that Tuesday from becoming the whole story. Without one, a normal losing streak plus one angry afternoon can do what a month of ordinary losses would not.
This is not only a rule on evaluation accounts. It is a practical cap on how much of your own pound capital one session is allowed to consume.
How Drawdown Actually Ends Accounts
The path is familiar. Size increases after a loss. Stops move. The trader who risked 0.5% per idea on the way up risks 3% on the way down because “this one looks clearer”. Correlated positions pile up: long sterling, long FTSE, both of which can fall together when the dollar is bid.
A free traders assessment is one way to see whether your losses are clustered in a few oversized sessions rather than spread as the plan described.
Leverage speeds the process. A 2% cash move is not exotic in GBP/USD or on the FTSE during a UK data morning. On a position that is too large, 2% in the market is not 2% on the account.
What Useful Limits Look Like
A working approach sets three numbers before the week starts: risk per trade, a daily stop, and a maximum overall drawdown at which you stand down and review. The review is the point. If you keep trading through a 15% hole with the same size, you have not “stayed disciplined”. You have declined to measure the damage.
Standing down is not quitting. It is refusing to let a temporary decline become a permanent one. Some traders cut size in half until they are back above a defined equity line. That is slower than the revenge trade. It is also how accounts survive.
If you do not know your current peak-to-trough figure, you cannot manage it. Write it down from the highest closed balance, not from memory.
Before you set those caps, a free traders assessment can show whether your recent equity path already exceeds the drawdown you would accept on paper.
Conclusion
Drawdown is the account’s fall from its high-water mark. It ends careers because recovery is mathematically harder than the decline, and because most people respond by taking more risk, not less. One trade rarely destroys a well-sized book. A 30% hole, plus the behaviour that follows it, often does.
Samuel and Co Trading treats drawdown as a core metric, not a footnote. Measure it from the peak, cap it in pounds, and reduce size when the number is growing. That will not remove losing weeks. It may keep there being a next week.
