i like to add an indicator script into my own script. what would be the best idea?

I am trying to use the indicator script zigzag into my own test script.

how would i load an indicator script into my own script?

would i use copy and paste? or is there a import function to load zigzag?

and if i would use copy and paste would i have to add it the top or at the bottom.

also i am a beginner in MQL4 programming. would also like some advise in what would be a good book to learn MQL 4 programming.

thanks in advance and happy pip hunting.

Your two codes must interact.

u can use iCustom(). you can find the description and example on MT4 lang reference

thank you for your answers.

just a follow up question.

if i understand correctly with icustom() i can import the results from the indicator.

however what would happen if i import a custom indicator that has a variable result?

like inchikomu for example?
