Hi, Molanis,
I would like to use custom indicator to create an EA, when I Generate MQL4 code, it showed that MQL compiler execution failed. On The error tab it shown that 1 error. The error message was \end of _program- unbalanced left parenthesis. May I know how to solved this problem?

Thank you for your help.

An error like end of _program- unbalanced left parenthesis is a sign that the import of the custom indicator failed. Most likely the indicator is not well written so the import function cannot get all variables and signals.
In your case the indicator is not well written so the import could'n recognize one variable. I made a quick change in the indicator to make it work.
Please use the attached indicator.

Hi, Molanis,

Currently, I have another Indicator want to create an EA, but I am facing the same problem as this one,
The error message was \end of _program- unbalanced left parenthesis. May I know how are you modified my previous Indicator? because I won't be able to see any difference between the original and modified indicators you have modified it for me. May I know how to solved this kind of error?

Thank you.

90% of the indicators need a simple edit: Add the indicator to a chart and look at the inputs. This will give you an idea of the variables involved.
Open the indicator with the metatrader editor (metaeditor). Look for variables definitions and clean them, do not leave comments after the variables
i.e.
extern int period=15; //period
extern int method=3; //method
extern int price=0; //enter a number

should be changed to

extern int period=15;
//period
extern int method=3;
//method
extern int price=0;
//enter a number

To fix the other 10% you need coding

I did not receive an authorization message stating that I am allowed to post yet until I am approved. I recently signed up and posted a reply, but I have not received the message stating that it was posted.

Why is there a delay?

I think you are off topic here. It's better to start a new thread for every new question. Anyway the forum gets lots of spam so a moderator has to review manually the first post and aprove it - we do not do this every day

Hi Molinas,

I am trying to create an EA using the attached indicator, which gives a digital reading using every tick. I keep getting the same error when trying to load the indicator. Can the strategy builder work for this indicator?
