This function is called by events (keyboard operation, mouse operation, object creation / modification / deletion) on the Chart. If there is no intended use, it is not necessary to include it in the program. OnTick () is not called if there is no price movement, so use this if you want to operate without price movement.

The first function to be called after loading the program. The call timing of each function is described in the sample program. It is usually said that the fewer external variables, the fewer bugs.Ī group of functions called from the MT4 Event handler. Set global variables that can be referenced in all functions in program creation. It also seems to have a function to raise the warning level when compiling the program.(It is better to describe it because it will reduce unintended programming mistakes.)
