Does Anybody Know How to Program Hot Key in NT?

[safetrading]

I have an indicator that accumulates data that I wish to reset to zero when certain market conditions occur. I note these conditions visually. Currently I just open the indicator window and click OK, which takes too much time in a fast moving market.

Does anyone know how I can program a hot key to reset the variable to zero that my indictor uses?

Thanks,

Hello safetrading,

There is option of right clicking > reload NinjaScript to reload the indicator. This can also be done with F5 key.

Hello safetrading,

I tried this, but it does nothing as regards changing the value of the indicator. The indicator only used live data, so every time I load it manually by opening the indicator window and clicking OK, it resets to zero, but when I tried the F5 after folowingthe instructions in the Hot Key help area, it does nothing. Am I missing something?

I see. Yeah, it won't reset values of inputs for example. If there were any code changes, these would be reflected after a reload NinjaScript.

Unfortunately this is outside our scope of NinjaScript support. Hopefully other community members with C# experience can share their input on keypress events.

Thx, I hope so, as the programming seems to be out of my reach.

Hi safetrading,

I was trying to perform the same task. I tried to use RegisterHotKey / UnregisterHotKey with P/Invoke importing user32.dll, but I ran into issues because the only way that seems usable is with a separate form or having access to the NT window message queue because you have to intercept WM_HOTKEY messages. Have you considered adding a button to the chart's toolbar? It is a much more simple approach without the overhead of P/Invoke or overkill of making an entire separate form. I can post what I am currently using if you like

Hi Dexter;

I hadn't thought of what you suggested. Yes, if you don't mind, it would be nice if you would post what you have done with the extra button.

Thanks,

Sure, here are the steps. It will add a simple text button after the properties button on a default chart.

First, add the forms namespace to your using region

using System.Windows.Forms; 

Add some variables in your variables region:

private ToolStrip        toolStrip;
private ToolStripButton    myButton; 

Next in either your Initialize() or OnStartUp() add the logic to find the default toolbar and create your own button

Control[] tsr = ChartControl.Controls.Find("tsrTool", false);
if(tsr != null)
{    
    toolStrip = (ToolStrip) tsr[0];
    if(toolStrip != null)
    {
        myButton = new ToolStripButton("Reset");
        myButton.Text = "Reset";
        myButton.Click += myButtonClick;
        toolStrip.Items.Add(myButton);
    }
} 

You'll need to create an event handler for the button delegate, this is where your desired reset code will go.

private void myButtonClick(object s, EventArgs e)
{
    // do whatever
} 

Lastly you'll need to remove your button when you remove your indicator. There may be a better way to do this but it works no problem for me so far.

protected override void OnTermination()
{
    toolStrip.Items.Remove(myButton);
    myButton = null;
    base.OnTermination();
} 

Give that a try and let me know if it works for you

Hi Dexter;

Very cool of you to provide such detailed information. I plugged it in ok, and just stuck the sample code below to test it, but with the sample code it would not compile;

EnterLongLimit(GetCurrentBid(), "Long Entry Test");

Any thoughts on this? I'm not much of a C# coder (obviously). If this is too time consuming for you I understand, and thanks very much for what you have already provided.

Could you paste the compile error you are getting? Also, is this a strategy or indicator? This will be a start for to get all set

You need to add the following line or it will not compile (failure to override an abstract base function)

  protected override void OnBarUpdate() {}

[Dexter]

Right, the code posted is what you'd plug into an existing indicator, not an entire one of course

safetrading, if you're still having issues could you post the error or listing?
