How to call iCustom

I am newbie coder, learning to code. I am trying to code an alert indicator that calls another indicator called "ABHA CENTER TIMING SIGNAL AVG" (found on FF but it has only ex4 file and no documentation or source code exists.)

I need to read its 0 buffer. It contains value 1, -1 or 0 in that buffer. Based on what is seen from the input parameters of this indicator, I have coded the iCustom call as under:

iCustom(NULL,0,"ABHA CENTER TIMING SIGNAL AVG",1,4,4,false,1,12,21,0,1)

I have also tried

iCustom(NULL,0,"ABHA CENTER TIMING SIGNAL AVG",0,1)


But none of it has worked.


Questions:

- can an indicator be called by another indicator by iCustom call?

- all extern parms show up in input window. Do all of them need to be listed as parm of iCustom call? Can there be anything else that need to be listed as parm of iCustom?.

Any suggestions or help?

your first code is correct. it should return the value of the the black line for the previous candle.

yes an indicator can call other indicators using iCustom.

yes all the params must match.

when you say it doesn't work, what do you mean? post your code here. perhaps its something else that's the problem.

Also check the Indicator's Empty Value. When calling iCustom it is useful, especially in arrow buffers.

Thanks guys. I got it to work. Both iCustom calls worked. I don't know what I was doing wrong. I renamed the indicator to a shorter name, reattached it to my chart, and iCustom calls began to work. This indicator appears to be great for generating scalping signals. Thanks.
