Why My Gold EA Shows Profit Factor 1.9 — And Why I'm Not Hiding It

If you have shopped for a gold EA recently, you have seen the screenshots. Profit Factor 20. Win rate 98%. Drawdown under 5%. Equity curves so smooth they look drawn with a ruler.

My EA does not look like that. Profit Factor 1.92. Drawdown 21.90%. And I want to explain why I am publishing those numbers instead of better-looking ones.

The two ways a backtest gets dressed up

There are two techniques that turn an ordinary strategy into a spectacular screenshot. Neither one is illegal. Both are common. Both change what you actually receive.

The first is lot scaling after losses. Increase position size after a losing trade and the equity curve smooths out, because losses get recovered quickly by the next larger position. Win rate climbs. Drawdown appears small — right up until the sequence of losses runs longer than the account can fund. Sellers rarely call this martingale. They call it recovery mode, adaptive sizing, smart compounding.

The second is deposit inflation. Drawdown is a percentage. Run the same strategy on $100,000 instead of $1,000 and a $5,000 loss becomes 5% instead of 500%. The trades are identical. Only the denominator changed. This is why you sometimes see "Initial deposit: 100,000" in the corner of a screenshot advertising 4% drawdown.

How to check for yourself

Ask the seller for one thing: the same test with a fixed lot size.

No compounding, no scaling, the same volume from the first trade to the last. Then compare the Profit Factor of the fixed-lot run against the compounded run.

If the strategy is honest, that number barely moves. Compounding changes how much you make, not how the strategy makes it. If the Profit Factor jumps dramatically once compounding is switched on, the position sizing is doing the work — not the entries.

My own numbers

Here is my gold system, XAUUSD M5, tested over 20 months on every tick with 99% history quality. 2,453 trades.

Profit Factor: 1.96 → 1.92 → 2.10 → 2.15. It barely moves. Position size here is tied only to how much the balance has grown — never to whether the last trade won or lost.

Drawdown sits between 17% and 22% across every configuration. That is not a comfortable number to publish next to competitors advertising 4%. It is, however, the number you would actually live through.

Why a Profit Factor near 2.0 is where honest systems land

Profit Factor is gross profit divided by gross loss. A value of 1.92 means the system earned $1.92 for every $1.00 it lost, across 2,453 trades spanning 20 months of gold markets — trending, ranging, news-driven, everything.

Values above 3.0 over a large sample are rare in real trading. Values of 10 or 20 usually indicate one of three things: a very small sample, a strategy that avoids realizing losses, or curve fitting to a specific period. None of those survive contact with a live account.

Sample size matters more than the headline number

A backtest with 300 trades can produce almost any Profit Factor by luck. One with 2,453 trades cannot. When you evaluate any EA, check the trade count before you look at anything else. If it is in the hundreds, the result tells you very little regardless of how good it looks.

What I would rather you see

I could have run my test on a $100,000 deposit and published a drawdown figure starting with a 2. I could have enabled a recovery mode and shown you a 98% win rate. Those screenshots would sell better.

But the person who buys based on a 4% drawdown figure and then watches their account draw down 25% does not stay a customer. They leave a one-star review, and they are right to.

So: Profit Factor 1.92. Drawdown 21.90%. Fixed-lot comparison included so you can verify the sizing logic yourself. Those are the numbers, and they are the ones that held up across 2,453 trades.
