Resolves YES if Manifold extends the current support for buying shares via limit orders to also allow for selling shares.

This will also resolve YES if there is a larger-scoped refactor of the ordering system that is judged (by me) to be equivalent.

Sep 17, 10:00am: In discord someone noted you can currently place a "buy" limit order in the opposite direction and set the price such that the shares cancel out. For the purposes here, this does not count - only new functionality that allows users to directly sell their previously bought shares via a limit order.
