EA from Indicator without source code possible ?

[metatrading]

Hello,

I am wondering if the creation of an EA is possible without knowing the source code of an indicator ?

If the indicator uses buffers, then you can access those buffers.

How can I know that ? The author does not answer at all.

If the values you need for trading appears in the Data Window then it is using buffers. Ask at the Freelance section for developers to look at the indicator to see if it is possible and how much it will cost to code the EA for you.

you can use the ex4,ex5 file of the indicator and the icustom function to declare and list the value of the indicator

Perhaps you should read the manual. iCustom

Just get the value(s) of the indicator(s) into EA/indicator (using iCustom) and do what you want with it.
