EA stopped working.

 
Can anyone help with that my EA stopped working since i have reinstalled mt5...Before that all trades are done by code... Stratergy tester shows no errors and giving results. No errors in code. But no trade is opening when i attached EA in chart even there is signal getting to buy or sell.  but code is attached fine . I have checked options and tools. All are correct. Is there any other issue about this?
 

If the EA does not act as intended start the work wit the debugger and other methods to control the calculation like Comment():
