How to read this: dark pools are private venues where institutions execute large trades away from public order books; the prints are reported through FINRA shortly after execution (the guide to how dark pool trading works covers the background). Prices where unusual volume accumulates are the reference prices traders watch when the market revisits them. Learn how Robinflow tracks dark pools
