The MT4 strategy tester report is one of the most information-dense documents you will encounter in retail forex trading, and most traders read less than 10% of what it actually contains. They look at the profit figure, glance at the equity curve, and move on. This is roughly equivalent to evaluating a business by reading only the revenue line and ignoring costs, margin, and cash flow. The full report tells a very different story if you know what each metric means.
Opening the Report
After running a backtest in MT4's strategy tester, click the "Report" tab at the bottom of the tester window. You can right-click anywhere on the report and select "Save as Report" to export an HTML file you can study offline or share. The report has three main sections: a summary table of key statistics, a graph showing balance and equity over time, and a detailed trade-by-trade log at the bottom.
Start with the summary table - but not at the top. The most important metrics are in the middle and lower portions of the table.
The Metrics That Matter Most
Profit Factor is the ratio of gross profit to gross loss. A profit factor of 1.5 means the strategy generated $1.50 in gross wins for every $1.00 in gross losses. Anything below 1.0 is an overall losing strategy. Solid strategies typically show profit factors between 1.3 and 2.5. A profit factor above 3.0 on a large trade sample is often a sign of overfitting rather than genuine edge.
Expected Payoff is the average profit or loss per trade. This is calculated by dividing net profit by the total number of trades. A positive expected payoff is necessary but not sufficient - you also need to know the distribution of results, not just the average.
Maximum Drawdown is reported in both absolute currency terms and as a percentage of peak balance. This is the most important risk metric in the report. A strategy that produces 30% annual returns but has a 40% maximum drawdown is not necessarily a good strategy - the drawdown tells you how much of your account could temporarily disappear before the strategy recovers. Compare this against your psychological and financial tolerance before deciding the strategy is viable for your account.
Recovery Factor divides net profit by maximum drawdown. A recovery factor of 3.0 means the net profit is three times the maximum drawdown experienced. Higher is better. A recovery factor below 1.0 means the strategy's worst drawdown exceeded its total profit - a poor result even if the ending balance is positive.
Sharpe Ratio measures return per unit of risk, adjusted for the risk-free rate. In strategy tester terms, it measures how smooth the equity curve is relative to the return generated. A Sharpe ratio above 1.0 is generally acceptable; above 2.0 is strong for a trading strategy. Very high Sharpe ratios (above 4-5) on large trade samples warrant scrutiny for overfitting.
Win Rate in Context
Win rate - the percentage of trades that close in profit - is the statistic most beginning traders focus on and one of the less informative in isolation. A strategy with a 70% win rate can be a losing strategy if the average loss is 3x the average win. A strategy with a 35% win rate can be very profitable if the average win is 3x the average loss.
The meaningful pair of statistics is win rate alongside the ratio of average win to average loss. These two numbers together define the strategy's edge. You can use them to calculate expected value: (win rate x average win) - (loss rate x average loss). If this number is positive, the strategy has a mathematical edge. If it is zero or negative, no amount of optimisation will make it consistently profitable.
Reading the Equity Curve
The graph section of the report shows balance (closed trades only) as a blue line and equity (including floating positions) as a green line. The gap between these two lines at any point represents open floating positions.
For grid and position-building strategies, the equity curve will frequently dip well below the balance line as open positions accumulate. This is normal for those strategy types - but the size of the gap matters. A strategy where equity drops 30% below balance on a regular basis is telling you that it holds large open floating losses as part of its normal operation. This is risk that the balance curve does not capture.
A smooth, consistent upward slope in the equity curve across the full test period is more reliable than a curve that surges in some periods and stagnates in others. High variance in the equity curve often indicates that results are heavily dependent on a small number of large winning trades, which makes future performance less predictable.
The Trade Log
Scroll to the bottom of the report to find the individual trade entries. This log shows entry and exit times, prices, lot sizes, profit/loss per trade, and cumulative balance. Reviewing the worst individual trades - not just the worst drawdown period - tells you about the strategy's tail risk. If the single worst trade represents a loss 5x the average loss, the strategy has occasional large outlier losses that the aggregate statistics are masking.
Also check the trade distribution over time. Are trades evenly distributed across the test period, or are there long gaps with no activity followed by clusters of trades? Uneven distribution can indicate that the strategy is sensitive to specific market conditions that may or may not recur in the future.
What the Report Cannot Tell You
The strategy tester report is a historical simulation, not a prediction. It cannot account for execution differences between backtesting and live trading, changing market conditions after the test period ends, or broker-specific spread and slippage patterns. Treat a strong report as a necessary but not sufficient condition for running a strategy live - it eliminates obviously broken approaches, but it does not guarantee future results. That judgment requires additional evidence from forward testing and, ultimately, live performance.
