Understanding Real-Time Trailing Drawdown
Real-time trailing drawdown (also called intraday trailing) tracks your highest unrealized balance tick by tick. Every time your account reaches a new high — even mid-trade — the drawdown floor permanently ratchets up. You can never get that cushion back. This requires precise entries and tight risk management, because a normal pullback after a winning streak can breach you.
How Trailing Drawdown Works
Trailing drawdown is the most common risk management rule in futures prop firms. Your maximum loss level (the "floor") starts at a fixed distance below your starting balance — typically $2,000-4,500 depending on account size. As your account balance increases, the floor moves up by the same amount.
The critical detail: the floor never moves back down. If your $50K account peaks at $52K (even briefly, even unrealized), the floor permanently moves from $48K to $50K. Your remaining buffer is now $2K instead of the original $4K. A normal pullback that would have been safe yesterday can now breach the account.
This is why many traders fail evaluations on profitable days — not losing ones. A strong morning run raises the floor, and a normal afternoon pullback breaches it. The simulator above demonstrates this effect with real numbers.
There are two variants: intraday trailing (floor moves tick-by-tick during the session) and EOD trailing (floor only updates at session close). Intraday is stricter because even momentary unrealized peaks tighten the floor. See how each behaves by switching between modes in the calculator.
Example Drawdown Scenarios
Scenario 1: Intraday Trailing (Evaluation Failed) — A trader on a $50K account with $2,000 drawdown has two strong days. Day 1 peaks at $51,280, tightening the floor to $49,280. Day 2 peaks at $52,560, floor moves to $50,560. On Day 3, a reversal drops the balance to $50,160 — below the $50,560 floor. Account breached, despite being profitable overall.
Scenario 2: EOD Trailing (Evaluation Passed) — Same trader, same market. With EOD trailing, Day 1's intraday peak doesn't move the floor — only the closing balance matters. Daily closes grind higher over 10 days. Scary intraday dips on Days 4 and 6 don't affect the floor. Profit target reached on Day 10. The breathing room from EOD trailing made all the difference.
Run both scenarios in the calculator above to see the exact numbers. Switch between "Trailing (Intraday)" and "Trailing (End of Day)" to compare side-by-side.
Trailing vs End-of-Day Drawdown
| Feature | Intraday Trailing | EOD Trailing | Static |
|---|---|---|---|
| Floor updates | Every tick (real-time) | Once per day (at close) | Never |
| Intraday peaks affect floor? | Yes — permanently | No — ignored | No |
| Difficulty | Hardest | Moderate | Easiest |
| Best for | Patient, precise traders | Day traders, scalpers | All trading styles |
| Risk of breach on profitable day | High | Low | Very low |
