Heartbeat Monitoring

[schollf]

Hey guys,

I would like to leave my strategy running on a computer were I do not have to monitor manually.
So the idea was some heartbeat signal...basically sending a http request to a monitoring website every 15mins or so.
The problem is that when you activate the strategy it will back load the last 5 or more trading days of data and send out a lot of requests for the past.
Is there any check I can do before sending the heartbeat to see if the strategy is still in the past...loading old data?

Thanks
Florian

Use State.Historical or State.Realtime.

great! Easy solution. Thank you!

Or use a timer, so you can communicate the fact that you haven't had any ticks or bars come in. If you do it in OnBarUpdate, then if there's no data coming in, it does not run. Of course, if the goal is for the external monitor to notice that you have not communicated, that may be enough.

Hello Florian,

Thanks for your post.

You could check if State == State.Historical or State.Realtime to check if the current state being processed is Historical or Realtime as bltdavid shared.

Or, you could consider implementing a timer in your script like QuantKey_Bruce suggested.

Here is a help guide page with sample code for implementing a timer: https://ninjatrader.com/support/help...ustomevent.htm
