Auto-Maximize Window Based On Signal

August 6th, 2017, 09:58 AM

Is there an existing script/feature for NT 7 that allows a signal to maximize a window of an instrument that has an alert/signal? Say for example you have a chart that has an alert signal that plays. That would be the cue to maximize the corresponding window. Heck I'm even willing to use NT8 not sure if NT8 has anything like that/.

This is what I have found so far:

Use this:

Code

using System.Windows.Forms;


	protected override void OnBarUpdate()
        {
		if (CurrentBar == 400)
		{
			ChartControl.FindForm().WindowState = FormWindowState.Maximized;
				
			// might also want to use these
			//ChartControl.FindForm().BringToFront();
			//ChartControl.FindForm().Show();
		}
        }

To test, just create a new chart with 300 bars, add the new indicator, then change the data series to have >400 bars and you will see the signal trigger the window to full size.

I have thought about putting similar into rfkFlipCharts for some time, but that code is easy enough for a simple single chart signal. Said Peter.

[NB** Add 'if (ChartControl != null)' tests if there is any chance of the code being used in a non-chart strategy.]

@ratfink Thanks for your response.

Any idea how i could possibly use it with bloodhound? So I have bloodhound (SiBloodHound) on panel 2 of my chart. The bloodhound plots a long confidence (1) or short confidence (-1) if the conditions are in place. Maybe that code you sent me above I place in panel 2 with bloodhound and monitor for the long/short confidence of 1 or -1 to maximize. It would have to be the indicator only on that chart since I have bloodhound on 20 other charts running.

In your situation you could possibly use bloodhound to create majority of the logic and just have the maximize code look at the 1 or -1 plot. That simplifies the whole situation.

I don't know Bloodhound at all, but you could write an indicator that takes any signal input (using the normal Ninja Indicator Input Parameter Dialog selection) and activates the maximise code line, the CurrentBar was just a test example.

Maybe another BloodHound user could chip in here.

@RosDaBoss

Here's a simple example including code and setup, just for testing in this case I've attached it to RSI. I'm assuming you can attach to BloodHound generated indicators in the same way. If not you will need to find out how to plug user code in by a different route.

Default signal values are +1 and -1 for BH (ignore the test values).

You could obviously add loads of other control mechanisms or gates, resets, etcetera.

Cheers

Code

using System.Windows.Forms;


namespace NinjaTrader.Indicator
{
    [Description("Enter the description of your new custom indicator here")]
    public class rfkMaxOnSignal : Indicator
    {
        private int longValue = 1;
        private int shortValue = -1;
        private int resetBars = 1;
		
	private int signalBar = -1;
		
		
        protected override void Initialize()
        {
            Overlay	= true;
        }

        protected override void OnBarUpdate()
        {
		if (Historical)
			return;
			
		if (Input[0] >= longValue || Input[0] <= shortValue)
		{
			if (CurrentBar >= signalBar + resetBars)
			{
				signalBar = CurrentBar;
					
				if (ChartControl != null)
				{
					ChartControl.FindForm().WindowState = FormWindowState.Maximized;
				}
			}
		}
        }
}

Thanks @ratfink for your support. I just got out of work. I got in contact with Shark Indicators just to verify the plot to select. Waiting for their response.
