🧠 How to read this page
Block (10k+ shares)
Single print of institutional size. Look for repeat blocks in the same direction — that's an algo working a parent order. Lone blocks at the bid = distribution; at the ask = accumulation.
Sweep
Order routed across multiple exchanges to fill urgency. Sweeps at the ask in options = informed buying. They precede news ~40% of the time.
OTC / Dark Pool
Trade matched off-exchange (FINRA TRF or ATS). "D" condition code. Often lagged tape — by the time you see it, the price has already moved. Use for confirmation, not anticipation.
