You can guarantee your selling price simply by submiting a normal limit order. What you won't guarantee is getting your share of any 'upside' to the Official Closing Price (OCP).Looking at this squeeze, am I selling at 900? 1000, 1100?
Or, you can guarantee that your shares will sell, and that you'll get the OCP. But what you won't guarantee is that the SP won't go up after-hrs.
There's no 'risk-free' lunch. I suggest either deciding in advance what SP you'd be satisfied sellling at, and make peace with that. Or play options if you want to trade closer to the wick.
GTLA (except the naked shortzes. those folks deserve what they get).
