pointvalue selected instrument

[manueldecastro]

Hello.
I am working on an indicator that will work on a graph with 2 instruments, mini and its micro. I can't access the pointvalue of the selected instrument in the chartrader.
I know the masterinstrument.pointvalue but it's not what I need. What I am looking for is that it returns the pointvalue of the selected instrument.
Could you help me?
Thanks in advance

private void OnChartTraderInstrumentSelectionChange(object sender, EventArgs e)
{
if (myInstrumentSelector.SelectedValue != null)
{
Instrument selectedInstrument = Instrument.GetInstrument(instrument);
}
}

i get the instrument selected selectedInstrument.PointValue is not working.

Hello manueldecastro,

Thank you for your post.

Have you tried using selectedInstrument.MasterInstrument.PointValue?

PointValue is only available from MasterInstrument, so this must be added to selectedInstrument.

Please let us know if you have any further questions.

selectedInstrument.MasterInstrument.PointValue
I think this is not possible, I was getting an error.
I finally fixed it with some if to determine the mini/micro instrument with .startwith
Regarding adding the .pointvalue to selected instrument, I don't understand how I could do it.
