How this service works
Bullflow.io is a real-time unusual options flow and dark pool tracker with advanced tools to view, filter, and analyze market activity as it happens.
Output
A paginated JSON object containing an array of dark pool trade rows, each with symbol, price, size, notional value in USD, trade timestamp in milliseconds, and trade date. The response also includes the query's from/to dates, ticker filter, minNotional filter, total count, limit, hasMore flag, and nextCursor for pagination.
Example use cases
Institutional block trade surveillance
“Show me all dark pool trades in NVDA from November 1 to November 14, 2025 where the notional is at least $1,000,000 — I want to see if institutions are quietly accumulating.”
Daily dark pool recap for a ticker
“Pull yesterday's dark pool trades for TSLA, up to 500 records, so I can see what off-exchange activity happened before today's open.”
Broad market dark pool scan
“Get all dark pool trades across any ticker from October 7 to October 10, 2025 with notional above $5,000,000, limited to 2,000 results — I'm looking for unusual large block prints.”
Technical details
Endpoint
GEThttps://api.bullflow.io/v1/data/darkPoolTrades?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical or recent dark pool (off-exchange, TRF-reported) trade data for a specific equity or ETF, especially for institutional flow analysis. Prefer this over options flow endpoints when the user's focus is on block equity trades executed off-exchange rather than options contracts. Best suited for date-range queries up to 30 days with optional ticker and notional filters.
Side effects
- Date range exceeds 30 calendar days — returns validation error
- Missing required 'from' or 'to' parameters — returns 400 bad request
- Invalid ticker format — returns empty rows or error
- Invalid cursor token — returns error or unexpected results
- Combining 'date' with 'from'/'to' params — returns validation error
- Rate limiting or payment failure — returns 402 or 429 response
