Flatten - not workin

[kujista]

Hello,

I tried to add logic to my strategy - flatten my position on specific chart.

I used Account.Flatten(instrumentsToClose); - I thought position will be flattened but it did not happen. What am I doing wrong?

and in StateDatLoaded I called

// instantiate a list of instruments
instrumentsToClose = new Collection<Instrument>();

// add instruments to the collection
instrumentsToClose.Add(Instrument.GetInstrument(Ac count.Name));

to initiate instrumentsToClose

What am I missing?

Thanks for advices

Hello Paul,

Thank you for your post.

The Instrument.GetInstrument() method requires that you pass in an instrument name, though it appears you are passing in Account.Name. For more information on the use of this method:

https://ninjatrader.com/support/helpGuides/nt8/getinstrument.htm

In the example on the Flatten page of the help guide, the instruments "MSFT" and "AAPL" are added to the instrumentsToClose collection:

// Please note that your 'Using declarations' section needs to have
//
// using System.Collections.ObjectModel;
//
// added in order for this example to compile correctly

 

// instantiate a list of instruments
Collection<Cbi.Instrument> instrumentsToClose = new Collection<Instrument>();        
 
// add instruments to the collection
instrumentsToClose.Add(Instrument.GetInstrument("AAPL"));        
instrumentsToClose.Add(Instrument.GetInstrument("MSFT"));
 
// pass the instrument collection to the Flatten() method to be flattened
Account.Flatten(instrumentsToClose);
​

I suspect this is the underlying issue; you could try printing the Count of your instrumentsToClose collection prior to calling Account.Flatten to see if it contains any elements to confirm this. For example:

Print("There are " + instrumentsToClose.Count + " instruments to be closed.");
Account.Flatten(instrumentsToClose);
