Currently Manifold supports spot buying, spot selling, and limit buying, but not limit selling.

If you hold some number of Yes (or No) shares, there's no way to say "if someone else tries to buy Yes (or No) shares at price X, then I'll sell my own Yes (or No) shares". This would be a Limit Sell, and is currently unsupported.

The closest you can do is either:

• Spot Sell: Repeatedly check back in on the market, and if the price ever reaches X, sell your shares manually

• Limit Buy: Put in a limit order such that if a person tries to buy Yes (or No) shares beyond a certain probability, then you will automatically buy some number of corresponding No (or Yes) shares to counteract them

This market will resolve Yes if any sort of limit selling functionality is added. This includes either or both:

• Being able to specify the share price you're willing to sell at

• Being able to specify the probability you're willing to sell at

If there are technical reasons that this is impossible to do, and a statement to this effect is made by the developers, or by someone with verifiable subject-matter-expert credentials, then this market will resolve to No prior to the stated resolution date.
