Problem when backtesting XAUUSD

[Gerardo Mathov]

I'm facing a very specific problem with MT5 when backtesting XAUUSD on Exness.

The Strategy Tester calculates profits correctly for each trade, but the exported HTML/XLS report multiplies the P/L by x10.

Example:  

For a 0.01 lot trade (1 ounce on Exness), the real P/L is ≈ $50, but the MT5 report shows ≈ $500.

This only happens in the export (HTML/XLS).  

Inside the terminal, the journal and Strategy Tester logs show the correct values.

Contract specification:  

- Contract size: 100  

- Min lot: 0.01  

- Tick size: 0.01  

- Tick value: 0.10 USD  

- Price precision: 3 digits

Is this a known MetaTrader 5 bug with gold (contract size 100)?  

Is there any way to force MT5 to export the correct P/L without the x10 multiplier?

Any workaround or setting that avoids the MT5 report multiplying gold profit by 10 would be greatly appreciated.

sounds like an issue you should be asking your broker for advice on.
