What does dark pool activity on OPEN mean?

Dark pools are private trading venues where institutions execute large block orders away from public exchanges. When OPEN prints unusually high off-exchange volume — measured as a multiple of its trailing 7-day average — it often signals that a large player is accumulating or distributing the name without moving the public bid/ask.

On its own, a dark pool spike isn't a trade signal. KAHF AI runs the KAHF Read on OPEN before flagging anything: conviction (volume ratio 3×+), direction (call/put flow), historical edge of the chosen structure at ~30 DTE, options liquidity, and catalyst + priced-in (is the move already in the IV?). Strong setups surface in Pro's daily email digest of unusual activity.
