Variable for Lot Size

[ekanters]

My problem is that 0.5 or 0.3 lot size is not accepted by the MT4 platform. Only round nrs like 1 or 3.
When the robot is dragged in its also impossible to change from 1 to 0.5

Its not the MT4 platform because 0.5 for example or any other lot size below 1 is excepted when using the MACD sample expert advisor.

So for whatever reason I can't use half lots.

PROBLEM SOLVED. I need to read better. Must be DOUBLE instead of INT.
