If fixed lots = 0.01 is used, it seems to open 1.0 lots XAUUSD
1.0 lots XAUUSD is actually 1000 Units on some brokers, not 1 Unit.
(1 unit XAUUSD is 0.01 lots for some brokers and 1.0 for others)
I'm not sure I understand your question, but I think maybe you're looking at the demo account and seeing XAUUSD being traded in one lot increments. I have a demo account and a live account, each with approximately the same amount of money. The last XAUUSD trade on the demo account traded 1.00 lots, and the live account (Pepperstone) traded 0.01 lots. I think the demo account just trades XAUUSD in 1.0 lot increments, but that doesn't mean your live account will do the same thing.@beren
