TradeRuler / Middle Mouse Button on Charts

[RonnyKeller]

I do love the "TradeRuler" from the "NT7 Indicators" section in this forum, and I'd like to have it in NT8, or at least sort of a "light" version. To begin with I'd need some advice about how to draw a short horizontal line at the High of a bar when middle-clicking below that bar or draw a horizontal line at the Low of a bar when middle-clicking somewhere above that bar.

How can I deal with a middle mouse button event on the Ninja charts in NT8?
How can I evaluate whether the mouse click happened either above or below a bar on the chart?
How can I find out above/below WHICH bar the middle button was clicked (bar number)?
How can I draw a short horizontal line that begins at the High or Low of a specific bar?

Perhaps someone could give me one or the other hint about how to begin? To me, missing such a TradeRuler "light" is one of only two or three missing pieces preventing me from switching to NT8.

Hello RonnyKeller,

This is not documented in the help guide, but you might try adding an event handler to the panel's MouseDown event.

For example:

else if (State == State.DataLoaded)
{
	ChartControl.ChartPanels[0].MouseDown += MiddleMouseButtonExample_MouseDown;
}
else if (State == State.Terminated)
{
	ChartControl.ChartPanels[0].MouseDown -= MiddleMouseButtonExample_MouseDown;
}

public void MiddleMouseButtonExample_MouseDown(object sender, MouseButtonEventArgs e)
{
	Print((e.MiddleButton == MouseButtonState.Pressed).ToString());
}

Perhaps I misunderstand, but how would this code-snippet help me decide on which bar the middle-button was clicked, or whether is clicked above / below a certain bar?

Hello RonnyKeller,

The suggested code shows how to capture a middle mouse click. You would get the x and y coordinates from the mouse click and then use custom logic to compare this with price or time values on the chart.

Below is a link to an example.

Thanks a lot, ChelseaB - your examples helped me to create my simple Risk-Ruler as uploaded recently to the NT8 AddOn-section
