How to code the multiple values of an indicator into another indicator?

[tradingmarkets4pips]

Let's use MACD as an example. It has 2-3 values(1 for the MACD line; the other for the signal line; 3 if it has a histogram).

I'm trying to incorporate those values into a new indicator. I figured I would need multiple buffers and SetIndexBuffer indicator calculations for the MACD indicator.

Need some help with all of the ins and outs.

Thanks in advance!

This is for MT5, but you can help out the MT4 peeps as well.

You're right. This must be done as you say. But maybe you don't need to use SetIndexBuffer. Just use the "CopyBuffer" function to get the MACD values.
