I only used the attached EasyOrder tool.
FNC_DB_EA does not automatically calculate the position size unless a Stop Loss (SL) is set.

It is recommended not to set the “One-way commission per lot” parameter.
For some instruments, it can cause errors in the lot size calculation.
This is simply based on Position Sizer, with unnecessary features hidden and the interface made more compact.
