1. Don't SHOUT at us, that is RUDE.

2. Perhaps you should read the manual.

             MQL4 Reference → Constants, Enumerations and Structures → Objects Constants → Object Types → OBJ_BUTTON - Object Types - Objects Constants - Constants, Enumerations and Structures - MQL4 Reference

3. Perhaps you should look at a GUI/Trade Assistant EA like mine (for MT4): 'Money Manager Graphic Tool' indicator by 'takycard' - Risk Management - Articles, Library comments - MQL5 programming forum - Page 6 #55 and understand how buttons are created and monitored.
