Issue with Account.Flatten

[daqu40]

I;ve emulated code from the NT 8 manual to flatten my positions but it is throwing an error:

Code:

Instrument myInstrument = Cbi.Instrument.GetInstrument("ES 12-15");
myAccount.Flatten(myInstrument);

Generates error CS1503 - Argument 1: cannot convert from 'NinjaTrader.Cbi.Instrument' to 'System.Collections.Generic.ICollection<NinjaTrade r.Cbi.Instrument>'

Not sure if this is a bug or I've done something wrong.

I've tried using just myAccount.Flatten(Instrument); and this doesn't work, however using myAccount.CancelAllOrders(Instrument); does work (compiles and closes orders as intended).

Thanks

I see our documentation is wrong here, I'll have that fixed up. Thanks.

It's looking for a collection of instruments, even if that is just one:

Account.Flatten(new [] { Instrument.GetInstrument("ES 12-15") });

Thanks Matthew,

Dissecting the error I figure this out. It would be helpful to others if the manual gets update to make this clear.

I've updated it now, please let me know if I can clarify anything else with this (or any other account) methods:
