Exit Strategy in Initialize()

[Oli]

Is there a way for me to make a Strategy terminate?

I would like to be able to build into my code a bunch of checking logic that if not satisfied will terminate the script.

Is this possible?

The suggested method is checking for the condition to stop your strategy from processing and return out of the OnBarUdpate() method.

if (StopStrategyFromRunningCondition == true)
return;

I should add, this should be called from OnBarUpdate() not Initialize(), I am unsure of implications of it being called there.

Thanks Ray,

I have been trying to set alerts with no luck, nothing happens:

Alert("string", Priority.Low,"Position Reported as Flat","C:\\Documents and Settings\\Trader\\My Documents\\Finance\\alert wavs\\alarm2.wav",5,Color.Beige,Color.AliceBlue);

The double \\ were necessary as the compiler keeps saying @unknown escape sequence@ which makes sense...

Maybe the Log is better than the Alert window...

Try this:

Alert("string", Priority.Low,"Position Reported as Flat",@"C:\Documents and Settings\Trader\My Documents\Finance\alert wavs\alarm2.wav",5,Color.Beige,Color.AliceBlue);

Also, I changed my post below, development corrected me and suggested not to set Running = false.

What is suggested is leaving the strategy running but returning out of OnBarUpdate().

So,

if (TerminateStrategyCondition == true)
return;

Still no good.

Am using this code with private bool Init = true; declared in variables :



protectedoverridevoid OnBarUpdate()

{

if (Init){

Alert("string", Priority.Low,"Position Reported as Flat",@"C:\Documents and Settings\Trader\My Documents\Finance\alert wavs\alarm2.wav",5,Color.Beige,Color.AliceBlue);



Log(Instrument + " reported FLAT", LogLevel.Information);

Init = false;

}

}

Ah yes the empty return... and the Log write works, only the Alert doesn't

[NinjaTrader_Ray]

For clarification,

- The alert will not compile?
- The alert does not generate an alert?

If the latter, alerts only trigger on real-time data, not historical.

Compiles and runs fine:

Chart is real time with live data

the condition Init is true under all conditions and should trigger OnBarUpdate.


The alert window remains empty

[NinjaTrader_Ray]

By the looks of your code sample, it should trigger only once on the first bar and not after that since you are setting Init= false.

If you create a new strategy an in the OnBarUpdate() include the following line, you will see alerts generated.

Alert("string", Priority.Low, "Position is reported as flat", @"C:\Program Files\NinjaTrader 6\Sounds\Alert1.wav", 5, Color.Black, Color.Yellow);
