A closer look
at dark pool data
Dark pools are trading venues that do not publicly display orders before execution. Their completed stock trades are reported. Bullflow brings reported off-exchange prints into a searchable feed; off-exchange trading also includes activity outside dark pools. Read the SEC’s explanation.
The feed shows trade time, ticker, price, share size, notional value, volume, percentage of volume, SigScore, and market capitalization where available. Filter by these fields, trade conditions, ticker lists, or date range, then export the current view as CSV.
Bullflow Premium includes real-time and historical dark pool access. Non-Premium accounts see a feed delayed by 24 hours. Ticker research, saved filters, and custom alerts depend on your plan; compare the current plans for access details.
SigScore ranks how unusual a trade is using factors such as notional value and price entry. Scores closer to 1 indicate more unusual activity. The score does not identify the buyer or seller, establish trade direction, or predict a price move.
Yes, on supported plans. Define your criteria in Dark Pool Flow and save an alert. The alerts panel collects matching prints so you can open a ticker and investigate the surrounding activity.
