Dark pool share: 32% off-exchange — 21pp below the market
Off-exchange prints never touch the public book, so they move size without moving the quote. That is the point of using them. Most of the day cleared on the lit market — either there was nothing to hide, or the large players sat out. Short share of the off-exchange piece: 75% vs a 62% norm.

What it means: The money signals for CWST are weak and mixed: off-exchange volume is below its 20-day norm, and the short share of that volume sits well above this stock's own norm, which points to hedging rather than quiet buying. Options data is thin, with no fresh open-interest or call/put flow reported.
News vs the money

Casella gets a permit expansion at its Hakes landfill in New York
The news is positive, but the money data shows no new call buying and off-exchange volume below normal, so the market is not visibly reacting to it.

Squarepoint Ops buys a new stake in Casella
The fund's new stake is a real institutional buy, but the current options and off-exchange data do not show matching accumulation, so the signal is modest.
Defense World · 09/21
Casella director sells $105,000 in shares
The insider sale is a negative-leaning headline, and the short share of off-exchange volume is above its norm, which lines up loosely with that cautious tone.

What is a “divergence”?
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).
