FlattenEverything

[soyjesus]

Hello,
If I have several strategies working on different charts (all on the same real account) and in one of these strategies I call "Account.FlattenEverything", are the positions of all the products/charts closed?

Hello soyjesus

The Account.Flatten() accepts an instrument would flatten everything on the account for that instrument. For any strategies with open positions this would cause them to be disabled.

Thanks Chelsea B., but which is the difference between "Account.Flatten()" and "FlatenEverything()"?

Hello soyjesus,

The Account.Flatten() method is a documented method in the help guide of which I can assist with using. FlattenEverything() is not a documented method and we do not have a specific expectation for its use.

Hello,

I'm using Account.Flatten() and the problem is that it closes the positions in the actual Account and in the rest of accounts too. And I want to close positions only in the Account in which I have inserted the strategy.

Hello soyjesus,

I am not able to reproduce this behavior.

To test I have created Sim102 account and opened a long position on both Sim101 and Sim102.

Then in an indicator, I have called
Account myAccount = Account.All.FirstOrDefault(a => a.Name == "Sim102");
myAccount.Flatten(new [] { Instrument.GetInstrument("ES 12-21") });

Only the position on the Sim102 account was flattened.

Below is a link to a video of the test.

This indicates that <Account>.Flatten() does work as intended.


If you are wanting to flatten only the strategy position in a NinjaScript Strategy. Call ExitLong() and ExitShort() in the strategy.

Question, While using the flatten() with a collection is using only realtime data required in all strategies to keep historical trades adding to tally.

Hello JLSwin,

The Flatten would be in relation to the Account position and not the strategy position. Any strategies running on those instruments that have a position open would be disabled.

Accounts positions are real-time.

Hello Chelsea and thanks for that helpful demo.

I'm wondering how to make the Flatten() method apply to whatever instrument of the chart the indicator is loaded on instead of a predefined string.

I can't find the syntax in the doc

How would it work? Thanks!

[NinjaTrader_ChelseaB]

Hello PaulMohn,

You would the Instrument of the Indicator class instead of Instrument.Get().

Try printing the instrument
Print(Instrument.ToString());

[PaulMohn]

Ok thanks a lot, so simply get it as string

myAccount.Flatten(new [] { Instrument.GetInstrument(Instrument.ToString()) }); 

It compiles ok. I'll test is asa. Thanks!

Hello PaulMohn,

myAccount.Flatten(new [] { Instrument });
