Hi experts.

If I want to add value to x variable every bar in function ontimer. How to code it?

Such as in TF H1,Ontimer,and x+1 every bar

at 6:00 , I set x to 0.

    7:00   x =1

    8:00  x=2

     9:00  x=3

thank you very much

 
For time based thing, use OnTimer. You want "every bar," use tick based (OnTick) and test for a new bar.
For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart,) volume is unreliable (miss ticks,) Price is unreliable (duplicate prices and The == operand. - MQL4 and MetaTrader 4 - MQL4 programming forum.) Always use time.
I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times.
