Hi Mathias
yes the indicator is in correct folder / directory and path is also defined correctly.
as I am using the same folder / path for another couple of other indicators and they all are working fine.
You have to study how Metatrader file sandbox looks like and how to reference files.
Do your includes work at all? Especially that one which starts with "C:\..." and those that start with "\..\".
Anyway, this is wrong:
m_IndicatorName = "Final Version\\iFx VW_3EMAs.mqh"; Here you have at least two problems:
- you can't use extension mqh, it's ex5
- if you call this from an expert, "m_indicatorname" without backslash character at the beginning would be appended to the current folder and indicator name as you wrote it resolves to:
Your indicator is in "Indicators" folder, probably something like this:
\Indicators\{some folder}\Final Version\iFx VW_3EMAs.ex5

Thanks a lot Drazen for your reply.
removing extension mqh, (what a silly mistake) worked and CLASS and EA is working now.
about the second part of your answer, the result differs.
************************************************************************************************
My EA Location : MQL5\Experts\AKTAdvisor\Testing EAs\EATest iVW 3EMAs.mq5
My CLASS Location : MQL5\Experts\AKTAdvisor\Indicator\CiVW_3EMAs.mqh
My Indicator Location : MQL5\Indicators\Final Version\iFx VW_MACD.ex5
************************************************************************************************
I am not sure why, but the following call in CLASS CiVW_3EMAs.mhq and than initialization of this class into EATest iVW_3EMAs.mqh is working well for this as well as for few other Classes I have created.
m_IndicatorName = "Final Version\\iFx VW_3EMAs"; // without file extension
Include statement in EATest iVW_3EMAs.mq5 is as below
#include "\..\Indicator\CiVW_3EMAs.mqh"
Currently this set up working well, except my silly mistake of adding file extension to IndicatorName.
However, I am open to learn better ways of coding and save time in future with errors. Your suggestion for structure array really helped me a lot, and I almost revising few of my initial work on those lines.
It is really having impact on my EA with less number of arrays to handle and less calls to different indicators. I have successfully merged 3 Indicator calls 1) %b, 2) %MFI and 3) %RSI into one single CLASS with following structure.
struct struct_NormBMR { double NormBB; double NormMFI; double NormRSI; } struct_NormBMR = sM05_NormBRM[];
Once again thanks a lot for your guidance and hopeful to receive them in future too.

UPDATE ... the issue is resolved, I was adding file extension in iCustom Indicator Name. Once removed it, it works well.
Dear Forum Members
It is never easy to use iCustom function in MQL5.
Please help me to debug why I am getting error 4802.
I have checked all the input variables of the indicator, nothing seems to be missing. Indicator .ex5 is attached for convenient debugging of Class and Test EA.
Indicator INPUT parameters ...
