Backtesting problem: Ordersize 0.01 not allowed

Hi,

when testing my EA I run into a problem. When I use a constant lotsize of 1.00 then the EA runs fine in the Strategy Tester. When I use the lotsize 0.01 I get error messages and no order is opened. The error message is indicating an invalid lotsize has been entered.

The same EA works fine on a demo account and on a real account. The problem occurs only in the Strategy Tester.

Is this a known ‘feature’ of MT4 or is this normal?

I can use 0.01 lot size in the tester without any problem. It works fine with several demo accounts from different brokers I had a problem with max lot size but that was a broker setting.

Are you sure this isn’t an issue with your EA ? that maybe there’s some coding that checks for lot sizes and there’s some error somewhere ?

I’ve never had an issue with 0.01 lot sizes in back testing.
