How Import a external Function in my Script (mql4)

[MatlabCoder98]

hi

as you know . mql4 library has not function about rate od change ( ROC )

and therefore i can not use it like ima or istoch ...

and i write a function for calculating ROC and save it namely iRoc.

how can i use it like internal function in mql4 ( iMA, iCCI,...)?

In future please post in the correct section.

I will move your topic to the MQL4 and Metatrader 4 section.

I have registered my functions in the include folder as a mqh file.

You can use iCustom() but this supposes to have the ROC.ex4 in your indicators folder. The other solution is to use the formula for current bar
