Check if subwindow is open regardless if there is an indicator on it or no ?

New comment
 

the Title say it all :)

any function for that ?


thanks

 
  1. There is no subwindow without an indicator on it.
  2. EAs have no eyes. They don't need visible indicators. So no. Just get the value(s) of the indicator(s) into EA/indicator (using iCustom) and do what you want with it.

well

i have created a dummy subwindow to be able to attach my EA dashboard controls inside it  ,  the problem when i switch to other TF another Subwindow is open again  , so there is no indicator on it to get a value 

everything is working as it should its just when i look into chart indicators i see few subwindows in the list .

How are you creating a subwindow without an indicator ?

Your issue is not clear. Please show your code if you need coding help.

#property indicator_separate_window


int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {
   return(rates_total);
  }

thats it and calling this from EA using


handle2=iCustom(_Symbol,_Period,"subwindow");

ChartIndicatorAdd(0,1,handle2);

Ok so you are well using an indicator.

Duplicate indicator at timeframe change - MQL5

RedTaurus, 2023.03.24 19:33

On Init()

indicatoreHandle  =  iCustom(_Symbol, TimeFrame, ".\PathUsata\indicatore.ex5", Periods, Multiplier);

// Aggiunge indicatore al grafico

   ChartIndicatorAdd(0, 0, indicatoreHandle   );



void OnDeinit(const int reason)
  {
        IndicatorRelease(indicatoreHandle  );

Hi everyone

In MQL5

I use the sequences above to load a custom indicator from EA to manage its results.

When I change the TF, the same indicator is reloaded with each change of TF, confusing the EA

How can I solve the problem?
