Minus 1 all the same. I also tried making the name of the indicator all small letters, also nothing.

Did you assign win_idx=1; ? Just take, and specifically set the subwindow number.

I tried it, it didn't help. Maybe it's the indicator, but the trades seem to open correctly?

I'll continue tomorrow, it's past my bedtime.

 

I read in the documentation that it is better to make the name of the indicator with parameters.

I did the following in the indicator:

IndicatorSetString(INDICATOR_SHORTNAME,"fraktalsdv("+Period_MA_1+","+ma_shift+","+price+","+Period_+")");

in the Expert Advisor:

string   shortName="fraktalsdv("+Period_MA_1+","+ma_shift+","+price+","+Period_+")";

The window with the indicator is not detected.

There is clearly a problem in your code, as the test script easily finds standard indicators that are displayed in the sub-window.

But, trades are opened and they are based on the indicator. And the indicator outputs correct values when it prints in the EA.

For some reason I think it's because the indicator doesn't have #property strict line (it doesn't work with it)

Somehow it seems to me that the indicator does not have #property strict line (it does not work with it)

No, it is not. Try function WindowFind()
 
Artyom Trishkin:
No, it's not. Try the WindowFind() function.
Returns -1.
 
forexman77:
Returns -1.

Look for errors. Indicators are normally searched through

intChartWindowFind(
longchart_id,// chart ID
string indicator_shortname // short indicator name, seeINDICATOR_SHORTNAME

 
forexman77:

No indicator window has been detected.

Do you want to find the indicator that the EA creates for the calculations on the chart? Good luck.
