In that case simply replace the following line :

[PHP]ExtMapBuffer1 = iCustom(Symbol2,0,"Supertrend",3,10,0,iShift2);I am assuming that the name of the indicator is "Supertrend"
I don' t want to replace, I want to integrate the supertrend code into this indicatore, and supertrend integrated is calculated on the indicator ExtMapBuffer1...

I am afraid I do not understand what does "integrate" mean
Would you care to explain more?

Then declare another buffer (for example ExtMapBuffer2) and use iCustom() to retrieve the values of super trend to that new buffer (something like this :
ExtMapBuffer2[i] =iCustom(Symbol2,0,"Supertrend",3,10,0,iShift2);

Sorry, but I really fail to see what are you trying to make (it seems as if you are trying to calculate super trend of some sort of a spread but I can ot tell from the code)
Why don't you start from the super trend indicator itself (since it seems that you are trying to change it)?
Yes,It is what I try to do:
1) create an indicator of the spread between 2 assets
2) calculate the Supertrend on the spread
I can not use the Supertrend with iCustom because it is loaded on the main chart and not on the spread created by me.
So, I' ve tried to follow this way (implement all the code of the spread and the supertrend in one indicator)

You can not do that (since super trend depends on things like atr - you would need to calculate the atr of that spread too and that is not possible). Also you are comparing current close price with that spread value which is not logical. This is the result with that atr used, but as I said, it does not have a meaning as it has in the original super trend, and you can not compare values from a complete different scale of values (close compared to spread, for example)
