Differences with strategy and copy

Hello 

I was copying strategy BerserkFX in june but I had to stop it because of the differences with his trades and my copy. My capital was about double of the strategy provider, so the copies should also be double from the provider.

With Forex pairs everything was ok but with the following symbols there were the diferences:

US30: BerserkFX trades micro lots and my copies was 1 lot, that represented x10. My broker is IC Markets and it seems doesn't allow micro lots in US30

WTI: BerserkFX trades WTI and my copies were XTIUSD, and while his volume was 10 lots mine were 50 lots when at that moment my equity was less than double 

Is the problem with my IC Markets account? I can not contact with BerserkFX and don't know what broker he uses or recomend

Thanks

Alberto
