ChartOpen does not return chart id

New comment
 

This is on MQL4. According to documentation, ChartOpen should return the new chart id. It doesnt. Therefore its a bug. Try this code in OnInit():

    long newChartID;
    long curChartID;
    
    curChartID = ChartID();
    Print("Current chart id: ", curChartID, ",  Current chart symbol: ",
        ChartSymbol(curChartID),",  Current chart timeframe: ",ChartPeriod(curChartID));
        
    newChartID = ChartOpen("EURUSD", PERIOD_D1);
    Print("New chart id: ", newChartID, ",  New chart symbol: ",
        ChartSymbol(newChartID),",  New chart timeframe: ",ChartPeriod(newChartID));
        

Run on a demo terminal.

 
Maybe it not work in OnInit, so try call it in other.
 

Works fine for me. Which build are you using?

Build 1045. And Im using in an EA, not an indicator.

It opens the chart, BUT, does not return the chart id.


Update: I tested it on a live chart, and it returns the new chart id. In other words. ChartOpen does NOT return the new chart id in Strategy Tester.

You have specified in the first post, that you ran it on the terminal rather than the tester.

I believe you may obtain reference only to the testing chart itself in the tester, to isolate the tester data from the future. Neither ChartNext() returns ID. (In fact neither the ChartFirst, which works in MT5).
