Error Operand expected but it is there

New comment
Hi, total noob here.  I have an error and several warning s but I cant work out the issue.  It says there is a '>=' - operand expected, but it is right there where it says the error is(marked in red background).  What am I missing??  Also does anyone know of a tutor to help with learning MQL4? Happy to pay an hourly rate.

at first define variables and make your calculation there

then use them instead

i modify your code and >= solved

Thanks Mohsen.  I was thinking of breaking it down like that.....  Is that something you suggest in the future to solve problems?  And really Thanks again!!

your welcome...what kind of problem do you mean?

if you have any question about mql you can pose in forum 

if u didnt raech to answer send me a messege...i will try my best

Your code
 
   if(MathMin(Open[i],Close[i])-Low[i])) >= (2*MathAbs(Open[i]-Close[i])) && Close[i] > (((High[i]-Low[i])/2)+Low[i]);
      return(true);
   return(false);
Simplified
 
return MathMin(Open[i],Close[i])-Low[i])) >= (2*MathAbs(Open[i]-Close[i])) && Close[i] > (((High[i]-Low[i])/2)+Low[i];
