Sui is the one to watch, this was the wild tape in an otherwise sleepy market.

Sui tumbled 4.14 percent and is sitting at 0.6488, just above its key support at 0.64451. It's still within its range, but if it loses that support, liquidity could dry up fast. Positioning is tilted lighter after a clear flush. This is the name most likely to deliver a fast follow-through if the mood sours again.
