Checking for time in OnStartUp

[federicoo]

Hello,

I want to wait for a specific time to send only one message and then start a strategy, so I want to do this under OnStarUp only one time before all the strategy other methods. I try this but the platform hang up:

protected override void OnStartUp()
{
while (DateTime.Now.TimeOfDay < triggerTime) // triggerTime is the time when I want to print the message
{
Print (" Waiting for this time: " + triggerTime.ToString());
}
Print (" Time Match!!!! ");
}

Thanks

Hello federico,

Thanks for opening the thread.

I am noticing the platform crashes when I place a loop comparing the DateTime. As NinjaTrader 7 is in a freeze, I will not be able to submit this matter for review and a workaround must be used.

I would suggest to create a return condition for OnBarUpdate() to prevent the code from executing unless a certain time of day is reached.

protected override void OnBarUpdate()
{
	if (DateTime.Now.TimeOfDay <= triggerTime.TimeOfDay)
	{
		Print("Message");
		return;
	}

Please let me know if I may be of further help.

Thank you,

Your code is fine, but I need to get total exact time to trigger some logic, so, if you put this under "OnBarUpdate()", you will have to wait for the next tick to check time, and this could take even seconds to coming in a new tick, so this loss accuracy, specially if you need a 1 second or less of precision.

BR,
Federico

Hello federicoo,

Thank you for your response.

You could utilize a timer to perform the same check. Please refer to the BarTimer indicator code in the NinjaScript Editor for an example of using a timer.

Please let me know if you have any questions.

Thanks,

Having the same issue, because the calls are under OnBarUpdate() and this have not a specific time precision taking place...

Hello frederico,

Thanks for writing back.

OnBarUpdate() requires ticks to place new bars. If you need some code to execute based on time without the need for incoming ticks, you will have to use a timer.

In addition to the BarTimer indicator, there is a sample provided on our forums that demonstrated how to apply a timer to a NinjaScript. The sample uses OnStartUp() to start the timer so it may by closer to what you are working for.
