how to set the indicator's input parameter from an Expert Adviser

[mikeitexpert]

I calling an indicator in my EA using iCustom, and the indicator has an input parameter. How can back-test the EA using different input values of the indicator's input parameter...

Of course I can set a default value and compile the indicator with different default input values. But, I don't want recompile it every time.

Please let me know what is the right way to do this. 

Thank you,

We can all use search here. It would be much more helpful if you posted an actual example

@hermestrading Here's an example of how a call to iCustom might be structured:

int myHandle = iCustom(_Symbol, _Period, "::Indicators\\<path\\to\\custom\\indicator>", [param_1, param_2,...param_n]);

- replace "<path\\to\\custom\\indicator>" with the correct path to your indicator.
- fill in the needed parameters at the end, after the path name. Separate multiple parameters with ', ' (comma).

Of course, this need to be in the appropriate event handler method, typically in OnInit().
Keep in mind this point from the iCustom docs (see @Philipp Negreshniy's link above:

[in] input-parameters of a custom indicator, separated by commas. Type and order of parameters must match. If there is no parameters specified, then default values will be used.

And remove the brackets to pass the actual parameters.
