Dark pool share: Off-exchange volume was quiet at 0.5× 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 (35.1%) may look normal, but the absolute size behind it was thin.

What it means: The options market leans toward calls on CYTK, but the most recent trading volume skewed toward puts, so the signals point in different directions. Off-exchange activity shows heavy short selling compared with the stock's usual pattern, which suggests quiet distribution rather than accumulation.

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).
