This is what's happened to me. My SP did one XAUUSD trade and My fixed lot size is 0.1. But instead of 0.1 lot, it only did 0.01 lot through myfxbook. So my profit 10 times smaller than it should be. My understanding is Fixed lot shouldn't be changed for any reasons otherwise it shouldn't call FIXED LOT SIZE? Pls give your thoughts.

Fixed lot size shouldn't be adjusted. This is a mistake. You should report it.

Yes. You can set a fixed lot size for all the trade at MFB. And I have a demo account having the same setting. The XAUUSD TRADED 0.1 lot as it should be.

It did again. If that's the case. You can't trade fixed lot size. if it is the other way around, you may lose your account in one trade just because you try to trade fixed lot size. It is wrong and seems very doggy!!!!!!!

The reason for the difference is different contract sizes between your account and the provider's. For example the provider's
XAUUSD contract size is 10oz while in your account it is 100oz hence the x10 difference. This is by design, in case you're basing your lot size on the provider's trades.
Do you wish it to be fixed in any case, even if different contract sizes?

Yes, Please. That's the size I want to trade basing on my broker lot size. that way you never need consider what SP's lot size is.
