Dark pool share: Off-exchange volume was quiet at 0.6× its norm
Off-exchange prints never touch the public book, so they move size without moving the quote. That is the point of using them. Large players were quiet in this name that day. The share (48.5%) may look normal, but the absolute size behind it was thin.

What it means: For JETS, the latest options data shows more calls than puts on both standing positions and recent trading, a mildly bullish lean. Off-exchange volume was normal and short activity was below its usual level, so there is no clear signal of big money accumulating or distributing.
News vs the money
Which airline stock did best in September: American, United, or Delta?
Delta's September gain is a backward-looking result, and the money data for JETS, an airline ETF, is neutral to mildly bullish, so the two do not clearly conflict.

Iran says it may reopen the Strait of Hormuz within a week; these stocks could gain most
A possible reopening would normally help airlines through lower fuel costs, and JETS's mildly call-leaning positioning points the same way, so there is no clear divergence.

Hormuz oil shipments rebound to a six-month high; which ETFs gain or lose if oil falls?
Easing supply risk generally supports airlines, and JETS's call-leaning options and normal off-exchange activity show no sign of money betting against that.

A divergence is when the news narrative and the institutional money flow point in opposite directions — a bearish headline while large call premium is bought, or heavy dark-pool selling under a bullish story. It signals the crowd and the desks may disagree.
How to read these numbers
Dark-pool volume — The share of trading executed off-exchange, at wholesalers and dark pools. About half of all US share volume prints there on an ordinary day, so the level by itself says almost nothing. What carries information is the distance from this name’s own recent norm, and whether the off-exchange size ran above its usual.
Off-exchange short share — How much of that off-exchange volume was sold short. The median across all listed names is about 49%, because wholesalers filling retail buy orders sell short and cover later. A reading near half is plumbing, not a bearish vote — compare it to the same name’s own 20-day norm.
Max pain — The price where the most options expire worthless — positioning often gravitates toward it near expiry.
Call wall / Put floor — Strikes with the heaviest call/put open interest — they often act as short-term resistance and support.
Put/Call ratio — Below ~0.7 leans bullish (more calls); above ~1 leans defensive (more puts).
