Lot size for MT5 EA

I think it will be like this:

No, I didn't compile - was late and I wrote from a pad.

But if you compile a code, then you will see directly where I inserted single excess letters :)

 Hello Vladimir ,your #1 post complied OK but your #3 post couldn't be complied.After I compare the code of those 2 posts  I found in this line 

          #include <Expert\Money\CMoneyFixedLot.mqh>             

 one letter C extra; I took off that C and now it is OK .Thank a lot for your help  and thank you whroder1 for your good idea.

Hello, I am trying to get the risk volume with your same code but the result is always 0,0.  Is there something wrong with this code or CMoneyFixedRisk class ? I only added 3 lines for this purpose. Thanks in advance.
