Stop strategy at a specific time

[Aqua-Life]

Hello all,

I was wondering how I can make my strategy stop at a specific time of day given the following parameters my strategy is using too:

- My strategy runs on a chart with Renko bars only. So there is no given time period on a bar close.
- My settings are "update on bar close".
- It runs every day, from Monday till Friday.

So question is: How can I make my strategy stop and close all positions and orders at a specific time reliably, (For instance, 9:30PM), and start up again the next day at the beginning of the day (For instance, 09:00AM)?


Thanks in advance!
Dennis

Hello Dennis, and thank you for your question.

Here is a modified version of some code from the help guide which should accomplish your goal. Please let us know if there are any other ways we can help.

        return;
    }

    // we can't trade before 9 AM
    if (ToTime(Time[0]) < 90000)
    {
        return;
    }

    // the rest of your OnBarUpdate code here
}

Okay, thanks for your reply and help.

What happens if the market doesn't move enough anymore to print another renko bar from 8PM till 10PM for example and I'm still in a position?
Cause there will be no more 'OnBarUpdate' and I do want to close the position at 9:30PM

In this case you will want to examine and adopt some of the custom event trigger code available from this link,

We are happy to help should any questions come up implementing any information from that link.

Hello Jessica,

Thanks for the info. I don't fully understand the logic how to set this up. I've tried some of it and came up with the following:

public class Test2: Strategy											
	{											
		private System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();
						
		protected override void OnStateChange()										
		{										
			myTimer.Interval = 1000;
		}										
				
		private void TimerEventProcessor(Object myObject, EventArgs myEventArgs)
		{
			TriggerCustomEvent(MyCustomHandler, 0, myTimer.Interval);
		}
		
		private void MyCustomHandler(object state)
		{
 			if(ToTime(Time[0]) > 213000)
			{
				ExitLong();
				ExitShort();
			}
		}
	}

It doesn't work yet but this is what i've got so far.

Hello Aqua-Life,

I noticed you are missing any hook methods NinjaTrader knows about. Because of this fact, NinjaTrader has no entry point into your class and, as such, no way to trigger anything within it including your timer. I would like to suggest avoiding timers if at all possible. NinjaTrader is truly event driven, and so every price change will cause NinjaTrader's hook methods to activate. If you need a timer so that something is absolutely guaranteed to happen regularly, it should still be in addition to an OnBarUpdate method.

There is some example code in this thread which can help you get started with implementing a 1 second timer should you decide OnBarUpdate's ability to trigger every price update is not suitable to your trading style.
