What's wrong with this indicator?
Unable to get the value of iCustom.
Returning 2147483647 ????
double EncogExample1 = iCustom(Symbol_1, 60, "EncogExample_Trained", false, 0, 0);
The indicator draws correctly. There is a value, but I could only get the EMPTY_VALUE.
What's wrong or missing in the indicator codes?
From your image it appears that the indicator does not draw a line on bar and 
that could be why you are getting EMPTY_VALUE
Check values for earlier bars.
Also make sure that you are calling the correct buffer index.
I was having the same problem on my EA. I solved it with a minimun bars before start the calculation of the EA.
Print("Less than 100 bars"); //number of bars according the minimum bars of the indicator that you are using, the 100 is only for the example, you need to use a variable with the number of periods for the indicator
//..... Your logic calling the indicator
