What is trailing drawdown? A prop trader's guide
By Santiago Álvarez Osuca ·
Trailing drawdown is the rule that quietly ends most funded accounts. Understand how it moves and it stops being a number you find out about too late.
The short definition
A trailing drawdown is a loss limit that follows your account's high-water mark. Instead of sitting at a fixed floor, the line that fails you trails your peak balance upward as you make money. Fall from that peak by more than the drawdown amount and the account is done. Most prop-firm evaluations and many funded accounts use one, which is why it deserves more attention than the profit target.
A worked example
Say you start a $50,000 account with a $2,000 trailing drawdown. Your minimum balance — the line you can't touch — begins at $48,000.
- You make $1,000. Balance $51,000, and the line trails up to $49,000.
- You make another $1,000. Balance $52,000, line at $50,000 — you're now above your original start, but so is the floor.
- You give back $1,500. Balance $50,500, still safe, but the line stays at $50,000. You now have only $500 of room.
Notice what happened: the drawdown climbed while you were winning and then locked in. That's the trap. Traders watch their balance go up and feel safer, while the distance to failure quietly shrinks.
The variations to check
Firms differ, so read your own account's exact terms — but the common variables are:
- What the trail tracks. Some trail your end-of-day balance; others trail intraday, following your unrealised peak tick by tick.
- Whether it stops trailing. Many trailing drawdowns freeze once your profit reaches a set level (often around your starting balance plus the drawdown), turning into a fixed floor from then on.
- Realised vs unrealised. Whether open-trade profit counts toward the high-water mark changes how close you really are.
These details decide whether a mid-session spike can move your floor, so they're worth knowing before you trade, not after.
Why it fails evals
Most blown evaluations aren't a strategy problem. They're one trade past the point of safety: a size-up to win back a red morning, or a slow drift down that crosses a line the trader had stopped watching. Because the trailing drawdown moves, the danger isn't fixed — it's closest right after a good run, exactly when discipline tends to slip.
How to keep it in view
- Know your current minimum balance at the start of every session, not your starting balance.
- Treat the distance to that line as your real risk budget for the day.
- Watch your equity curve fall and recover in real terms, so the gap to the limit stays in front of you.
- Journal the sessions where you got close, and what set it off — that's where the pattern shows up.
How Wickary helps
Wickary keeps each prop account on its own book with its own balance, and its equity curve moves trade by trade off one P&L formula that handles futures point values and forex contract sizes the same way. You watch the account fall and recover in real terms, so the distance to your limit stays visible instead of being a number you notice too late. You set the limits that match your firm; we don't invent their rules for you.
