Problem using a Custom Indicator from an EA.

[V Q]

Hello,

I have just write my first very simple custom indicator (returns -1 or +1 for candlestick of a determined size) . It can be added mannually to a chart properly, but I have problems using it from an EA.  The think is that when I test and visualize the EA, the indicator is shown well in the chart of the visual test window and a positive number is the result of iCustom call, and everything is ok, BUT when I add the compiled EA to a chart, the indicator does not appairs, and -1 is the result of the iCustom call. Any idea about why???  

Thanks in advance.

EA INDICATOR CALL CODE

oninit

{

.....

   ArrayResize(ics_array, ics_array_size); 
 ics = iCustom(NULL, 0,  "i1//iCandleSignal",  i_white_size,  i_white_size_range);
 Comment(IntegerToString(ics));

 ChartIndicatorAdd(handlex, 0, ics);

ChartRedraw(handlex);

...

}

Please EDIT your post, when posting code you have to use SRC button.

What is that value of handlex variable  ?

 ChartIndicatorAdd(handlex, 0, ics);

[Jian Chen]

ics = iCustom(NULL, 0,  "i1//iCandleSignal",  i_white_size,  i_white_size_range);

The third parameter could be wrong. You should change it to:

ics = iCustom(NULL, 0,  "i1\\iCandleSignal",  i_white_size,  i_white_size_range);
