Dark pool share: Only 39% vs a 48% norm of the off-exchange volume was short
Off-exchange prints never touch the public book, so they move size without moving the quote. That is the point of using them. Size was ordinary, but the sell side was light within it — not aggressive accumulation, yet no real selling pressure either.
Source: FINRA · Fri 10/9 close
What it means: Dark-pool activity for ANET is accumulation-like: off-exchange volume ran about 17% above its 20-day norm, with a short share (38.8%) well below its own norm (48.2%). Options positioning leans call-heavy on standing open interest (put/call 0.71), while recent traded volume is balanced, so the signals are only moderately aligned.

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).
