Using Custom Indicator in EA

New comment
 

Guys can any one advise on how I can use any of the custom indicators in my EA.  For example, How can I use Fourier_Extrapolator_of_Price.mq5, I mean what do I do to be able to call the indicator and how do I know what variable to use if for example,  I want the 5th Future price.  I guess the input paratmenters will be the Symbol, Time frame and the 4 inputes described in the code it self (Npast, Nfut, NHarm & FreqTOL). 

I am sure gpwr will be able to answer this but dont know how busy he is.  I will very much appreciate any help you any one.

Thanks  in advance.

I will not list all of the new possibilities and features of the new terminal and language. They are numerous, and some novelties are worth the discussion in a separate article. Also there is no code here, written with object-oriented programming, it is a too serous topic to be simply mentioned in a context as additional advantages for developers. In this article we will consider the indicators, their structure, drawing, types and their programming details, as compared to MQL4. I hope that this article will be useful both for beginners and experienced developers, maybe some of them will find something new.
 
We have  lots of articles here. See for instance MQL5 for Newbies: Guide to Using Technical Indicators in Expert Advisors
