Made two trades, but I'm not very sure about them, so I didn't dare to trade in the account. Currently, it seems that the idea is correct, so let me share a bit.

$skate plummeted after the contract was launched and then started to rally. $bid is similar, it also rallied in the afternoon until just now.

The logic for shorting is very simple; since the market maker has pushed so much, they must want to squeeze shorts. However, before the fee is charged, there is no fixed rate to lock in the -2 fee, making it impossible to collect once an hour and unable to form the conditions for short squeezing. This indicates that the market maker has strength but not much.
