Creating EA with custom indicators


Hello everyone

please i am in need of serious help

I have been trying to build an EA with this custom indicator Supertrend oma histo that i downloaded free from the market.

I am still learning the MQL5 programming language, all i intend doing is getting the EA to pick signals with the custom indicator from the indicator window and users should be able to change the indicator inputs and modify them according their observations.

who has an idea on how to write the code to pick the parameters from the indicator inside the indicator window and pick trades as the values change?
