Detect Suspended

[QuantKey_Bruce]

If IsSuspendedWhileInactive is true (which it is, by default), and NinjaTrader is going to suspend the indicator (let's say, perhaps, the user switched another workspace to be active), this should trigger an event in any running NinjaScript before the suspend takes place, and another event when calculations resume. It could look something like this OnIsSuspendedChange(bool IsSuspended). It is not necessary to allow the indicator to abort the suspension - after all, if the indicator did not want to be suspended it would set IsSuspendedWhileInactive to false. But, this gives the indicator a way to detect when it's getting ready to suspend and a cleaner way to detect when it's been resumed - this way, resources can be handled better and it can incorporate any needed custom logic for these situations in the best way.

Hello bltdavid,

Thanks for your note.

+1 please. I'd even settle for something as simple as a flag for the indicator that indicated its status (IsSuspended). Not unreasonable as an additional way to check these things.

Thanks.

Yes, except that if it's suspended, it isn't running anymore so you don't get to see the flag during OnBarUpdate, OnMarketData, etc. unless you're perhaps executing a timer possibly? That's why I asked for an event - so we would be notified right BEFORE it suspends, rather than after it's already suspended. But, yes, absolutely, I agree with you wholeheartedly - anything is better than nothing.
