Your account must have other assets in it to have been allowed to short 100 AMC in the first place. If there are no other assets in your account then the -100 AMC and 10 AAPL your account would have a net value of 0. Which means you would have already been in a margin call prior to this.

Yes

And those other assets must be closed, or apple must be closed, to actually reduce margin use. That was my whole point. You don't just get to close AMC and reduce your use of margin. It's a net zero because going short AMC is paired with going long something else, generally. If you ONLY had the AMC short to account for, then yes, you can close it at will but yeah, this isn't how the game is being played.
