Can strategies close positions they didn't create?

[NinjaCustomer]

I just want to verify what I want to do is possible before trying to create a Strategy myself.

Can strategies close positions they did not themselves open?

I occasionally click buy or sell mkt buttons an extra time to open another contract accidentally. It doesn't happen often but I would like to write a Strategy that will close any extra contracts as soon as they are opened.

Hello NinjaCustomer,

A Strategy can adopt a position and then close that position.

Below is a public link to a forum post on adopting a position.

But without adopting the position a strategy is not able to see any position that instance of the strategy did not create.

But an addon can loop through an account's positions and close the position.

Below is a public link to the help guide on Addons.
