But not everything can be added this way, levels, colour are missing in iMA;

probably IndicatorCreate should be dismantled with MqlParam

these parameters are not set in any way when creating the indicator.

Thanks, I'll keep that in mind.

And I have the following question.

Can I add a custom indicator to OBJ_CHART? And if so, how?

See EA_OBJPROP_CHART_ID

Hello!

If you look in the handbook (MKL), you can see:

DBL_MAX	The maximum value that can be represented by the type double	1.7976931348623158e+308

1.7976931348623158e+308 is a number that has 309 whole digits! Of course this can't be. Maybe I'm wrong? But then how should we interpret this entry ( 1.79769313483623158e+308 )?

That's why I didn't think that an indicator can be placed on a chart via a handle, if it is used for calculations in memory... This is probably the reason why the parameters responsible for the chart are not set.

[Olegs Kucerenko]

Make a custom version of the indicator, with an input colour parameter, and load it via iCustom with the colour as a parameter.

[Andrew Petras]

That looks like it. Thank you. (Laughs) At least now there's a framework in my head :)

Hello, I am looking for an EA that is not working correctly and I am trying to close positions with my hands. I have tried to reboot the terminal, deleted the logs and history, but it did not help.

I tried to restart the terminal, delete the logs and history does not help ... Maybe someone will tell me.

No, I think it's clear.
