Do you have the same balance?
Ah, I just saw what you mean, the less profit has to do with slippage problems between you and signal's provider broker.
XAUUSD is a difficult instrument and has a lot of slippage between brokers.
Do you use the same broker?
What allocation do you have set?
If its less than 95% then, there's your reason (among others like slippage between brokers).
Yes, of course, by setting it to 95% you will get 3 times more profit or losses (don't forget those as well).
