Blanket flattening using flatten()

[JLSwin]

Guys,
. Looking at creating an indicator that when certain criteria is met, it will flatten all positions linked to that account. I know it can do it for a single instrument, and multiple instruments, but how can it be done for any instrument tied to that account?

Thanks in advance John

Hello JLSwin,

Thank you for your post.

To flatten a list of instruments on an account you would need to call Flatten() for a collection of instruments. First, you would initiate a list of instruments, add instruments to that collection, then pass the instrument collection to the Flatten() method to flatten all instruments in that list.

See an example of this and more information in the help guide documentation below.
