Most of the time, the market is in a "long gamma" position
Technically, this means that flows are absorbed by the hedging behavior of market makers- stabilizing the market overall and compressing ranges over time.
But compare today to yesterday?
If you're zoned in, this probably "feels" like negative gamma
but guess what...
it's still significantly positive overall.
It's just a major RELATIVE change in regime, comparing yesterday's totals to today's totals.
