Completely different results with the same expert on four BROKERS

[Maurizio Lucini]

Please help me understand: I am running the tester strategy with an expert of the MT5 market on gold with four different brokers Dukascopy, Swissquote, FP-Market and Ava-Trade and I get completely different results.

In particular with Swissquote and Dukascopy the result from 01.01.24 to today is the same for both at about 4 million euros with an initial deposit of 10,000 euros.

With Ava Trade and FP Market it is 100 times lower at about 35,000 euros.

The leverage is 1:400, the Drowdown is the same and also the number of operations carried out about 300 and the lost operations about 40.

I get the same result using real ticks of Dukescopy downloaded from TickStore on the four experts.

Please help me understand how it is possible for this to happen and which of the results should I consider real??

Thank you so much to anyone who helps me because I'm racking my brains to understand but I can't find reasonable answers on my own.
