A dealer hedging an options book adjusts the underlying as delta changes. In equities that adjustment happens during the session, and everything left over is carried across a closed market.
Crypto never closes, so hedging is continuous. The consequences are larger than they sound.
Three equity behaviours that do not transfer
The closing-auction hedge. A large share of equity dealer hedging concentrates into the close, because it is the last and deepest liquidity of the day. Crypto has no close and therefore no such concentration — hedging spreads evenly instead of clustering.
Overnight gap risk. An equity dealer carries unhedged exposure across a market they cannot trade in. A crypto dealer never has to, which reduces the premium they need for that risk and is one reason to expect structurally different pricing.
The opening imbalance. No open, so no accumulated overnight order flow arriving at once.
Where the risk goes instead
Into liquidity. A dealer who can always hedge still cannot always hedge well — and the hours when hedging is most needed are frequently the thinnest, per weekend gamma and why spreads widen.
So the equity dealer’s problem is time risk they cannot trade through. The crypto dealer’s is execution risk in a market that is open and shallow. Neither is obviously worse; they are different, and they produce different pricing.
Why it matters for reading the map
Because it removes the intraday rhythm an equity reader expects. There is no build into a close and no reset at an open, so a crypto gamma level does not have a time of day at which it is most likely to assert itself.
The one genuine scheduled moment is 08:00 UTC, and on most days even that is small.
