Home · Learn · Trailing drawdown
On a trailing account your risk is front-loaded. Until the floor locks, profit buys you no extra room at all — and the account is at its most fragile on the day you are least familiar with it.
A trailing drawdown limit follows your balance upward. Make money, and the floor beneath you rises by the same amount, so the gap between the two stays constant. It is usually explained as a generous feature: your gains are protected.
Read the other way, it says something less comfortable. While the threshold is trailing, profit does not widen your buffer. Ten thousand dollars of gains buys exactly zero extra tolerance for losses.
But it does not trail forever, and this is the part that decides how the account actually behaves. On most futures programmes the floor locks once it reaches your starting balance — after that it is fixed, and every further dollar of profit finally becomes real armour.
Worked through on a $100,000 account with a $4,000 trailing threshold, risking $700 a trade. This programme locks the floor at $100 above the starting balance, once the end-of-day balance clears the drawdown by $100 — so the lock triggers at $104,100 and the floor freezes at $100,100.
| Balance | Floor | Room | Full stops it survives | Phase |
|---|---|---|---|---|
| $100,000 | $96,000 | $4,000 | 5 | trailing |
| $102,000 | $98,000 | $4,000 | 5 | trailing |
| $104,100 | $100,100 | $4,000 | 5 | locks here |
| $108,000 | $100,100 | $7,900 | 11 | locked |
| $120,000 | $100,100 | $19,900 | 28 | locked |
Two different accounts, in effect. Below the lock you survive five consecutive stops no matter how well you have been doing. Above it, the same strategy and the same size survive eleven, then twenty-eight. Nothing about your trading changed; the rule stopped following you.
So the risk is front-loaded, which is the opposite of how it feels. A funded account is at its most fragile on day one — when you are least familiar with the platform, the fills and your own behaviour under a live rule set — and it gets structurally safer the further past the lock you go. Most traders assume the reverse: that small early gains are the safe part and risk arrives later with size.
The practical consequence: the climb to the lock is the phase to trade smallest in, not the phase to press. Getting past it is worth more than any individual winning day, because it permanently changes how many mistakes the account can absorb.
These are not small print. They change the arithmetic above materially, and they are stated in your programme's rules — go and read which one you are on.
Take the harder phase — before the lock, where the example above survives five consecutive stops and no more. The question becomes: how likely is a run of five?
That is entirely a function of your loss rate, and it moves fast:
| Win rate | Chance any given trade loses | Chance of 5 straight losses | Roughly once every… |
|---|---|---|---|
| 90% | 10% | 0.0010% | 100,000 trades |
| 80% | 20% | 0.0320% | 3,125 trades |
| 70% | 30% | 0.2430% | 412 trades |
| 60% | 40% | 1.0240% | 98 trades |
| 50% | 50% | 3.1250% | 32 trades |
The rightmost column is the one to sit with. At a 60% win rate, a five-loss streak turns up roughly every hundred trades — which for an active scalper is weeks, not years. At 90% it is effectively never. (These assume independent trades. Real losses cluster, because the conditions that cause one tend to persist, so treat every figure here as the optimistic case.)
This is the honest argument for a high-hit-rate structure on a funded account, and it is a real one. It is also where it stops being comfortable.
Your win rate is an estimate, taken from a sample. The table above assumes it is a constant. It is not.
Watch what happens when a 90% system degrades — not collapses, just drifts, the way strategies do when volatility regime changes:
| If the true win rate is… | Chance of 5 straight | Versus 90% |
|---|---|---|
| 90% | 0.0010% | — |
| 85% | 0.0076% | 7.6× more likely |
| 80% | 0.0320% | 32× more likely |
| 70% | 0.2430% | 243× more likely |
A twenty-point drop in win rate makes account death 243 times more likely. The strategy has not stopped working — a 70% win rate is a good strategy — but the risk model built on 90% has quietly stopped applying, and nothing announces it. The equity curve still looks fine right up until the run that ends it.
So the trade-off, stated plainly: a high hit rate with a wide stop is genuinely safer on a trailing account while the hit rate holds, and it is unusually fragile to the hit rate being wrong. A lower-hit-rate system with a tight stop survives being wrong about itself much better, because it was never depending on streak-freedom in the first place.
None of this requires a particular strategy, indicator or platform. It requires knowing two numbers and being honest about the second one.
If you want to see this arithmetic run against a specific record rather than round numbers, the simulator on our homepage replays a 19-month history through $50K, $100K and $150K account rules — including the months that lose. It will show you the failure cases, because those are the interesting ones.
Run the drawdown simulatorProbabilities shown assume independent outcomes and a constant win rate; real trading satisfies neither assumption, and clustered losses make streaks more likely than the figures above. Drawdown rules vary between funded-account providers — check your own programme's terms. Nothing here is financial advice. Futures trading involves substantial risk of loss and is not suitable for every investor.
