What your drawdown is actually telling you

Every funded account has a drawdown limit, and most traders treat it as a wall to stay away from. It is more useful as a readout. How deep a drawdown goes, how fast it came and how long it lasts say more about how you trade than your win rate does.

How drawdown is measured

Drawdown is the fall from the highest point your balance or equity has reached, the peak, to the lowest point after it, the trough. It is measured from the peak, not from where you started. A worked example: an account opens at $100,000, climbs to $106,000 and then slides to $100,700. The account is still up, but it is in a $5,300 drawdown, which is 5.0% of the $106,000 peak. Maximum drawdown is the deepest such fall over a period. Current drawdown is how far below the last peak you are right now, and it is 0 when you are at a new high. Daily drawdown is the loss within one trading day, usually counted from that day's starting balance or equity.

Trailing or static: read your firm's rule before you size

Prop firms measure the same idea in different ways, and the difference decides how much room you have. A static limit is fixed to the starting balance: with a 10% maximum loss on a $100,000 account, the floor stays at $90,000 whatever happens next. A trailing limit follows your highest balance or equity: a $10,000 trailing limit puts the floor at $96,000 once you have touched $106,000. Take the account above at $100,700. Under the static rule it has $10,700 of room left, under the trailing one only $4,700, less than half. Firms also differ on whether open positions count, when the daily limit resets and whether a trailing floor stops moving at the starting balance. Read the rule for the exact account you trade, and size from the room you actually have rather than from the headline percentage.

A limit is a constraint, a curve is information

Two traders can both sit 4% below their peak and be in completely different situations. One got there in a single oversized loss. The other bled through eleven small ones. The first has a sizing problem that a rule change fixes tonight. The second has an edge problem that no rule change will touch. The number is identical, and only the curve separates them. So before you ask how deep a drawdown is, ask two other questions: how many trades built it, and did any single loss go past the 1R you planned.

Losing streaks are shorter than they feel and longer than you plan for

Streaks are arithmetic, not luck. If trades are independent of each other, a 45% win rate gives about a 73% chance of six or more losses in a row somewhere in the next 100 trades, and about a 31% chance of eight or more. At a 50% win rate the figures are about 55% and 17%. Now put that next to your size. Risking 1% of the balance per trade, six straight losses cost about 5.9%. Risking 2%, the same six cost about 11.4%, which is already past a 10% limit. If a streak your own win rate makes likely would breach the account, the account was lost the moment you chose the size, and the market simply had not got there yet. Size so that the longest streak you expect still leaves room under the limit.

Measure the depth in R, then the way back

A percentage tells you how close you are to the limit. R tells you what the drawdown means for the strategy. At 1% risk per trade, a 6% drawdown is roughly 6R. At 0.5% risk, the same 6% is 12R, a much deeper hole for the same system. Expectancy tells you the way back: a strategy that makes +0.25R per trade on average needs about 48 trades to earn back 12R, and real results will scatter around that figure. Recovery in percent is also lopsided. A 10% drawdown needs an 11.1% gain to get back to the peak, a 20% drawdown needs 25%, and a 50% drawdown needs 100%. This is why many traders cut size early in a drawdown rather than late.

Read it per model, not per account

The account curve tells you whether you are still in the challenge. The per-model curve tells you what to do about it. When one model contributes most of the depth while another quietly compounds, the answer is rarely to trade less. It is to trade less of that one. The split is easy to miss when results are only added up per account. In Haunted, pick a model in the Analytics filter and the equity curve, maximum drawdown, current drawdown and longest losing streak are recalculated for that model alone, so you can see which one dug the hole.

A weekly drawdown check

Five questions keep a drawdown from turning into a surprise. How far am I below the last peak, in percent and in R? How much room is left under the daily and the maximum limit of each account, by the firm's own rules? How long is the current losing streak compared with the longest one I have had? Which model or session contributes most of the depth? And did any loss go past −1R through slippage or a moved stop? If the answers are consistent with your own history, you are inside the normal range of your system and the job is to keep executing the plan. If they are not, that is the signal to cut size and review before the next trade.

Is daily drawdown or max drawdown the one to watch?

Both, for different reasons. Daily drawdown ends accounts faster, because one bad session can use up the whole daily budget. Maximum drawdown is the one that ends the challenge. Track both against the firm's own rules, per account.

How do you calculate maximum drawdown?

Find each peak of the equity curve and the lowest point after it, express the fall as a share of that peak, and keep the largest. With a peak of $106,000 and a later low of $100,700, the drawdown is $5,300 divided by $106,000, which is 5.0%.

What is the difference between trailing and static drawdown?

A static limit is set once from the starting balance and does not move. A trailing limit rises with your highest balance or equity, so every new high also raises the floor. In the example above, the same account at $100,700 has $10,700 of room under a static rule and $4,700 under a trailing one.

How deep a drawdown is normal?

There is no universal number. It depends on your win rate, your risk per trade and your average R. What matters is whether the depth and the streak you are seeing are consistent with your own history, and a journal is where that history lives.
