Programatically bring chart which generated pop-up window to front
03 Jun 2024, 20:23
Hello!
I would like to achieve what the title says. My indicator generates signals and based on them I get pop-ups.
Almost everything works as intended, except “teleporting” me to a chart which generated the signal. How to achieve this?
Here is the code snippet for MessageBox (aka pop-up window:) ):
var _mbox = MessageBox.Show(Chart.SymbolName + " Take Long at " + DateTime.Now, "Long mode on " + Chart.SymbolName, MessageBoxButton.OK, MessageBoxImage.Information), MessageBoxResult.OK);
Print(_mbox);
if (_mbox == MessageBoxResult.OK)
Chart.TryChangeTimeFrameAndSymbol(Chart.TimeFrame,Chart.SymbolName); <-- my attempt...Best,
Łukasz

}how the signals are generated is dealt with inside of switch (haSigBoundary) and the functions:

{

Print(_mbox);
if (_mbox == MessageBoxResult.OK)
Chart.TryChangeTimeFrameAndSymbol(Chart.TimeFrame,Chart.SymbolName);
}
if (Double.IsNaN(lngSig[i - 1]))
lngSig[i - 1] = avgPrice[i - 1];
lngSig[i] = avgPrice[i];
_lng = true;
_shrt = false;
}
private void markShort(int i)
{
if (Double.IsNaN(shrtSig[i - 1]) && _barIndex != i && IsLastBar)// && ((Server.Time - Bars.Last(0).OpenTime) < _maxDiff))
{
_barIndex = i;
var _mbox = MessageBox.Show(DateTime.Now.TimeOfDay.ToString().Substring(0,8) + "\n" + "Short\n" + Chart.SymbolName, "Short mode on " + Chart.SymbolName, MessageBoxButton.OK, MessageBoxImage.Information), MessageBoxResult.OK);
Print(_mbox);
if (_mbox == MessageBoxResult.OK)
Chart.TryChangeTimeFrameAndSymbol(Chart.TimeFrame,Chart.SymbolName);
}
if (Double.IsNaN(shrtSig[i - 1]))
shrtSig[i - 1] = avgPrice[i - 1];
shrtSig[i] = avgPrice[i];
_lng = false;
_shrt = true;
}are respoonsible for coloring the signal line.
To reproduce:
- Attach indicator to multiple charts in the same program window (best will be with small time frame like 1minute or even 10 - 20 ticks, depending on volatility)
- Wait for crossing of signal line with channel middle (with default settings)
- The messagebox should come. Click ok.
After clicking ok I expect to be taken to the chart that generate the signal in the box. I couldn't find any function in CTrader's help that would what I am asking for.
