A large share of institutional volume trades off-exchange, in dark pools, and prints to the tape after the fact. Those “dark-pool prints” are a rough window into where big size is changing hands — a flow signal that complements the structural dealer levels. NoVo computes this directly off the live tape in-house — no third-party flow vendor — surfacing sweeps & block prints per ticker on the Analyst dealer map.
What a print does and doesn't tell you
A large dark-pool print at a price says significant institutional volume transacted there — often a level worth marking. But there's a catch: a print alone doesn't reveal direction. You usually can't tell from the print whether the institution was a buyer or a seller, and it reports with a delay. So it's a “something happened here” signal, not a “they're bullish” one. Treat it as a level of interest, not a directional call.
Pairing it with the map
Dark-pool prints get powerful in confluence. A heavy print stacked on a gamma wall or the flip is a level with both structural and flow backing — the positioning and the big money pointing at the same price. That's stronger than either signal alone, and it's the right way to use prints: as a second source that confirms or questions a level, not as a standalone edge.
A print marks where size traded; it doesn't say which way. Its value is confirming a level, not predicting a direction.
The honest limits
Dark-pool data is partial, delayed, and easy to over-read — plenty of prints are hedging or mechanical, not conviction. Aggregated over time it feeds indicators like DIX, which is more useful than any single print. Use prints as one modest input to reading positioning, weighted below the structural map, and you'll avoid the trap of treating a lagging footprint as a crystal ball.
