Use the debugger or print out your variables, including _LastError and prices and find out why. Do you really expect us to debug your code for you?
By a quick check your ea uses iCustom indicators....
'If' some one would be interested to debug your code,at least provide all indicators as without them it's going to be impossible.
Here they are
There appear to be NO ERRORS and I am debugging in real and everything seems to be right so far. I have also noticed that it missed some trades. The indicators generate pop-up signals, so I am not sure if that might be overloading the MT4 platform and that is why it cannot work properly.
