Catching termination of strategy...

[heech]

Hi,

Is there anything I can do, to execute some clean-up code when my strategy is *terminated*? Some kind of global finalize?

The problem is I'm using the .NET FileSystemWatcher class, so I can monitor changes to one of my configuration file. If I modify a file, my strategy real-time reloads some parameters, etc.

When I terminate the strategy, I'd like to stop monitoring the configuration file. So far, haven't seen a way of doing that.

Hi heech, I think the method you're looking for is Dispose().

Hi heech, I think the method you're looking for is Dispose().

That's it! Thank you sir.

Hi Heech, Austin,

Recalling my memory I would say that Dispose() is only called when you remove the strategy.

If my memory is correct: Once a strategy gets flat after a trade the strategy has realized P/L and (true?) start/stop cell becomes stopped.

But to call Dispose() one must manually remove the strategy.


So maybe you should monitor the change of the cells start/stop or realized P/L of the strategies' row in the grid?
You can do this, you must get access to the SourceGrid2
strategyGridDisplay1 (possible, but undocumented) and then you can add a IBehaviorModel to the cell in question. (look through sourcegrid2.dll) . OnValueChanged(..) is a good place to put your stop filesystemwatcher code.

best regards
Andreas

You are exactly right. I've just tested this. For my purposes for now, I will just be sure to "remove strategy".

I'd love to hear more about these undocumented features though, if you've built up a collection of similar things we can automate! Any clever ways to programmatically disconnect/reconnect, or start a new strategy, for example?

with NT7 coming soon I think one should concentrate on other parts in the strategy logic. Undocumented features will definetely change.


For example I have added a parameters dialog ( pops up when clicking the strategy's parameter cell) where I can change the strategy parameters after the strategy has already started.
