What is recovery factor? Reading net profit against drawdown
Recovery factor combines net profit and maximum drawdown into a single ratio. This compact metric still depends on how drawdown is defined, how long the test period is and which configuration was used.
What is recovery factor? In the way it is commonly used in EA reports, it is net profit divided by maximum drawdown. It tells you how many times larger the end-of-period profit is than the largest recorded drawdown, under the report's own definitions and units. It does not tell you how quickly the account recovers, and it does not guarantee that drawdown will not get deeper in the future.
Formula and interpretation
Recovery factor is calculated by dividing net profit by max drawdown as defined in the report. You need to establish whether max drawdown here is a money value or a percentage, and whether it is balance or equity, because the choice of denominator changes the ratio. Check the platform's legend and compare the formula against the published fields before comparing two EAs.
| Result pattern | What recovery factor may suggest | What to check next |
|---|---|---|
| Positive net profit, moderate DD | End-of-period profit is larger than the observed DD. | Test length and recovery time. |
| Small net profit, large DD | The ratio may be low. | Costs, period and configuration. |
| Very small DD over a short period | The ratio may look impressive. | Trade sample and volatility not yet encountered. |
| Negative net profit | Should not be read as a simple ranking. | The ratio and how the report handles the sign. |
Example from a published EA report
M1 REGIME backtest report, period 1 Jan – 2 Oct 2026, initial deposit 300 USD: 268 trades, net profit 324 USD, profit factor 1.68 and maximum balance drawdown 14.53%. These are published Strategy Tester figures, not live account results. The sample is still short and does not guarantee future results. See the report and test conditions on the EA page.
How a long or short test period changes the meaning
Recovery factor usually rises when cumulative end-of-period profit grows while maximum drawdown stays the same. As a result, the ratio for a long period can be higher than for a shorter one even if most of the profit came from a few favorable months. Conversely, a short period may not yet have hit a typical drawdown. Always read the start and end dates, the equity curve, profit by year or month, and the time spent below the peak.
The metric does not reflect recovery speed. Two systems with the same ratio can differ in time spent below the peak, number of losing trades and how concentrated the profit is. If the report does not show recovery time, do not infer that the EA recovers quickly just because the metric is called recovery factor.
Limits when comparing recovery factor
The ratio is affected by many choices: balance or equity drawdown, the type of starting capital, trade volume, how net profit is calculated, swap and commission. Using drawdown in money alongside net profit in the same unit usually gives a ratio that is easier to compare, but you still need the same configuration and test period. Comparing reports from two accounts with different capital while ignoring lot size can be misleading.
A high number can also appear because the sample has not yet gone through an unfavorable period, or because drawdown is measured on balance and excludes open trades. Check equity drawdown, open-position risk, trade sequences and tick data. Look into whether many configurations were tested and only the one with the highest ratio was published.
If recovery factor is used to screen several EAs, keep the same measurement period and calculation rules for each report. Note clearly which cases lack equity drawdown or costs, to avoid lopsided comparisons. Do not replace missing values with zero, and do not derive recovery factor from a cropped screenshot that does not state the formula. A comparison metric is only useful when the reader can reproduce the calculation.
Which metrics should you read alongside it?
- Net profit and initial deposit, to understand the scale of the result.
- Balance and equity drawdown, to see both closed and open trades.
- Profit factor and number of trades, to understand the sample behind the ratio.
- Test duration, recovery time and results by period.
- Trading costs, spread, commission and data quality.
Recovery factor is useful as a summary placed next to other fields, not as the only criterion for choosing an EA. If the figures lack definitions or do not state the test period, ask for the original report. Do not rank two strategies by a single ratio without agreeing on how it is measured.
Recovery factor is a ratio calculated from simulated history. It does not prove that an EA can recover from drawdown in live trading, and it cannot cap future losses.

Frequently asked questions
It is usually net profit divided by maximum drawdown, according to the report's formula. Confirm the type of drawdown and the unit.
There is no universal threshold. A comparison only means something when the drawdown definition, test period, capital and configuration are equivalent.
No. The ratio does not describe recovery time; you need to look at the equity curve and the time spent below the peak.
The calculation depends on the platform or report. Check the formula to see whether the denominator is money, a percentage or some other value.
Cumulative net profit and maximum drawdown change with the time window; a short period may not yet have recorded an unfavorable phase.
