How to get the result from default indicator?

[gogoknow]

Hi all, i am newbie of Mql4, i am trying to write my own code, i want to leverage some result of default indicator, i tried to get them by my coding, but don't why doesn't work. I guess (rates_total) is the result of the indicator, so i created a variable for storage of result:

int Awesome_result = 0;

And after calculation, i will get the result into Awesome_result by following: 

 Awesome_result += rates_total;  // store the result into Awesome_result

However, and then i printed, nothing happens, can i anyone tell me what wrong with my code? the following is the whole code, thx a lot

Does that even compile?

   return(rates_total);
   Awesome_result += rates_total;  // store the result into Awesome_result

You return before doing the calculation!

Print (Awesome_result );

This appears to be outside of any function.

Topics concerning MT4 and MQL4 have their own section.

In future please post in the correct section.

I have moved your topic to the MQL4 and Metatrader 4 section.

1. There is no such thing as a "default indicator"
2. You show the code for the "Awesome" indicator. You don't show the code of how you read it.

   Perhaps you should read the manual. Detailed explanation of iCustom - MQL4 programming forum 2017.05.23
