How to Read a Strategy Tester Report
A tester report contains dozens of numbers, few of which matter. Worse, the most prominent of them — total profit and win rate — say the least about the system.
Start with the trade count
The first thing to look at is how many trades the report contains. At a couple of dozen, none of the other figures can be interpreted: dispersion on such a sample swamps any difference between systems. A report with excellent metrics and thirty trades tells you nothing except that thirty outcomes went one way or the other.
Profit without drawdown means nothing
Total return only has meaning alongside maximum drawdown and recovery time. Doubling a deposit with a 60 percent drawdown is not a doubling; it is information that the account was nearly destroyed along the way. What to look at is the ratio of return to drawdown, not return by itself.
Win rate traps
A high win rate is achieved trivially: a close target and a distant stop produce nine wins out of ten and one loss that covers them all. The reverse is also true — trend systems live with win rates below a third. The figure is neither good nor bad on its own and can only be read together with average win and average loss.
The curve matters more than the total
The shape of the equity curve says more than all the numbers together. Smooth growth with rare setbacks indicates either a good system or a fitted one. A step, where all the profit came from one stretch, means the system earned on a single market regime and has no bearing on the others. Long flat sections show how much time you would spend without results — something the report's figures do not reflect at all.

Frequently asked questions
Where do I start when reading a tester report?
With the trade count. On a sample of a few dozen the other metrics cannot be interpreted, because dispersion swamps any difference between systems.
Why is a high win rate not a good indicator?
Because it is trivially achieved with a close target and a distant stop, producing many small wins and a rare large loss. It must be read alongside average win and average loss.
What matters more than total profit?
Maximum drawdown, recovery time and the shape of the equity curve. Profit earned in one burst on one stretch of history indicates a match with a market regime, not system quality.
