Traders who bet on a higher $SOXL with borrowed money were hit by a wave of forced closures. In the last 30 minutes the major venues liquidated $1.7M of long positions, shutting them once the collateral behind them could no longer cover the losses.

The other side barely moved. Short positions liquidated over the same half hour came to $82.2K.

Both totals come from the raw liquidation streams of the major venues.
