How to code to read value from first indicator's data inside Expert Advisor?

Help needed ,

I have a Expert advisor that need to read the crossing of Moving Average from a CCI[14] . I have two Moving average of 2 and 7 which i applied using  first indicator's data to the CCI[14].

From this link https://forum.mql4.com/55157 the only way to read the MA value is to create a custoCCIm indicator and then use iCustom to read the value.

I having problem creating the custom indicator where the lines draw not the same as original. Refer to the diagram below

 I have attached my custom indicator coding below. Anyone can enlighten me what is wrong. How come my Moving average value not the same as the built in original which i drag from Navigator
