The simplest drawdown formula is:
Drawdown % = (Peak value - Current value) / Peak value × 100
That formula is easy. The mistakes happen when traders use the wrong peak or the wrong current value. In MT5, balance and equity tell different stories. Balance only changes when trades close. Equity changes while trades are open. If your EA holds floating losses, equity drawdown is the earlier warning.
Common MT5 drawdown types
| Type | Calculation | Best use |
|---|---|---|
| Balance drawdown | Peak balance to current balance | Closed-trade reporting and fixed account summaries. |
| Equity drawdown | Peak equity to current equity | Live risk monitoring while trades are open. |
| Daily drawdown | Day baseline to current equity or balance | Prop firm daily loss rules and intraday risk alerts. |
| Max drawdown | Highest reference value to lowest later value | Strategy evaluation and account survival analysis. |
Example: calculating equity drawdown
Imagine a $50,000 MT5 account. During the week, equity reaches a peak of $52,000. Later, open positions pull current equity down to $49,400.
The drawdown is ($52,000 - $49,400) / $52,000 × 100 = 5.00%. Even if the account balance still shows $51,000 because trades have not closed, the equity drawdown is already 5%.
This is why a serious MT5 monitor should calculate drawdown from equity in real time. Waiting for closed trades can make an alert arrive after the useful decision window has passed.
Daily drawdown formula
Daily drawdown depends on the rule. Some firms calculate from the start-of-day balance. Some use start-of-day equity. Some trail from the highest intraday equity. Before building an alert, define the baseline:
- Static daily loss: start-of-day balance minus allowed loss.
- Equity-based daily loss: current equity must stay above the daily floor.
- Trailing daily loss: the floor may move upward as equity makes a new intraday high.
The guide Prop firm daily drawdown rules explained covers those rule types in more detail.
Turning calculations into alerts
The calculation should produce action thresholds, not just a number on a page. For example, if the daily limit is 5%, set a warning at 3.5%, a serious alert at 4.25% and a critical alert at 4.75%. The exact values depend on your strategy, but staged alerts are better than a single panic message at the limit.
In xTriel, drawdown alerts sit next to live account telemetry from the read-only MT5 Reporter EA. That lets the dashboard combine equity, balance, open P/L, heartbeat and account rules instead of asking you to calculate risk from terminal screenshots.
What a drawdown calculator cannot tell you
Drawdown tells you how far the account has moved against its reference point. It does not explain why. A spike in drawdown might come from spread widening, correlated pairs, a martingale step, oversized lots or a stale terminal that stopped managing exits. Pair the calculator with trade-level and account-level monitoring.
