# Drawdown > The decline from a peak account balance to a subsequent low, measured as a percentage or absolute value. At a prop firm, breaching a drawdown limit ends the funded account. ## AI Snippet What is drawdown in trading? Drawdown is the decline from a peak account balance to a subsequent low, measured as a percentage. A 10% drawdown requires an 11% gain to recover. A 50% drawdown requires 100%. This non-linear maths is why a deep drawdown is hard to come back from. For prop firm traders, breaching a daily or trailing drawdown limit means losing the funded account entirely. ## What Drawdown is Drawdown is the decline from a peak account balance to a subsequent low point, measured as a percentage or absolute value. A trader who grows their account from $10,000 to $12,000 and then drops to $10,800 has experienced a 10% drawdown from the peak. Drawdown is a standard measure of risk in trading performance. Two types of drawdown matter in practice. Daily drawdown is the maximum decline permitted within a single trading day. Trailing drawdown tracks the decline from the highest account balance reached, so the limit rises with the account. Firms differ on which limits they set, and each firm's rules define them. Breach a limit the firm sets, and the trader loses their funded account. This makes drawdown rules a risk parameter a prop trader cannot breach and stay funded. Drawdown and tilt can feed each other. Near a 5% daily limit, a trader at 4% has little room left, and recovery-driven decisions (larger positions, faster entries, abandoned analysis) can breach the limit within minutes. Discentra's rules look for several of those decisions in the trade data: a re-entry at a larger size after a loss, five or more trades in fifteen minutes, and a trade above the size limit the firm has declared. The mathematics of drawdown recovery amplify the problem. A 10% drawdown requires an 11% gain to recover. A 25% drawdown requires 33%. A 50% drawdown requires 100%. This non-linear relationship means a moderate drawdown takes a modest gain to repair, while a large one needs a much larger gain; overleveraging and revenge trading are two ways a drawdown gets large fast. ## Why it matters for institutions For prop firm traders, breaching a drawdown limit means losing the funded account entirely. For retail brokerage clients, a deep drawdown can trigger a margin call. A firm can check in its own data how many traders stay after either. For prop firms, brokers and crypto exchanges, the speed of a drawdown may matter as well as its size, and a firm can test in its own data whether fast losses come before exits more often than slow ones. A trader who loses 5% over two weeks processes it one way. A trader who loses 5% in twenty minutes processes it another, with less time to settle before the next decision. Discentra's rules watch the trades inside a fast loss (a larger re-entry, a burst of trades, the declared daily loss limit), so a call can reach the trader before the next one.

Drawdown is the decline from a peak account balance to a subsequent low, measured as a percentage or absolute value. A trader who grows an account from $10,000 to $12,000 and then drops to $10,800 has taken a 10% drawdown from the peak. It is a standard measure of risk in trading performance, and for prop firms it is a hard limit. ### What is the difference between daily and trailing drawdown? Daily drawdown is the maximum decline permitted within a single trading day. Trailing drawdown tracks the decline from the highest account balance reached, so the limit rises with the account. Firms differ on which limits they set, and breaching one means the trader loses their funded account. This makes drawdown rules a risk parameter a prop trader cannot breach and stay funded. ### Does the speed of a drawdown matter as well as its size? It can. A trader who loses 5% over two weeks has time to absorb it; a trader who loses 5% in twenty minutes makes the next decision while the stress response is still running, with adrenaline arriving within seconds and cortisol peaking 21 to 40 minutes after the loss. A firm can test in its own data whether fast losses come before exits more often than slow ones. ### Why is a large drawdown so hard to recover from? The maths is non-linear. A 10% drawdown requires an 11% gain to recover. A 25% drawdown requires 33%. A 50% drawdown requires 100%. A moderate drawdown takes a modest gain to repair; a large one needs a much larger gain, and overleveraging and revenge trading are two ways a drawdown gets large in a single session. ## Related terms - [Tilt](https://discentra.ai/glossary/tilt) - [Overleveraging](https://discentra.ai/glossary/overleveraging) - [Revenge Trading](https://discentra.ai/glossary/revenge-trading) - [Intervention Window](https://discentra.ai/glossary/intervention-window) ## Further reading - [Discentra for Prop Firms](https://discentra.ai/prop-firms) - [Prevent Tilt: Use Case](https://discentra.ai/use-cases/prevent-tilt) --- This is a Markdown mirror of [https://discentra.ai/glossary/drawdown](https://discentra.ai/glossary/drawdown).
