Raw Flow Data API: Trade-Tape Proxy Endpoints
Raw 1-minute options and stocks trade-tape data: per-symbol recent trades, summaries, blocks, minute history, cumulative net flow, and cross-symbol scans for leaderboards and outliers.
Raw Flow vs Flow Analytics
The /v1/flow/options/* and /v1/flow/stocks/* endpoints are pass-through proxies on top of FlashAlpha's ingest service. They return raw trade-tape rollups (recent trades, minute buckets, blocks, cumulative net flow) with camelCase field names, distinct from the snake_case Flow Analytics surface that recomputes GEX, walls, pin risk, and dealer risk on the OI simulator.
Use raw flow when you need the underlying trade-tape data itself (per-trade rows, minute VWAP, buy/sell volume splits) or when you want to scan the universe for the busiest symbols. Use Flow Analytics when you need derived, decision-ready exposure signals. All raw endpoints require the Alpha plan or higher.
Endpoints
Per-symbol options flow
Five rollups of the options trade tape for a single underlying.
/v1/flow/options/{symbol}/recent
Recent option trades across all contracts for an underlying, newest first.
/v1/flow/options/{symbol}/summary
Option trade-flow totals across all contracts: buy/sell/mid/net volume, biggest single trade, last trade time.
/v1/flow/options/{symbol}/blocks
Large option trades across all contracts, filtered by minimum contract size.
/v1/flow/options/{symbol}/history
Minute option-flow buckets rolled up by underlying with buy/sell/mid/net volume, VWAP, high/low.
/v1/flow/options/{symbol}/cumulative
Running cumulative net option flow by underlying with per-minute VWAP and trade counts.
Per-symbol stocks flow
The same five rollups for the equity trade tape.
/v1/flow/stocks/{symbol}/recent
Recent stock trades for a symbol, newest first.
/v1/flow/stocks/{symbol}/summary
Stock trade-flow totals: buy/sell/mid/net share volume, biggest single trade, last trade time.
/v1/flow/stocks/{symbol}/blocks
Large stock trades for a symbol, filtered by minimum share size.
/v1/flow/stocks/{symbol}/history
Minute stock-flow buckets with buy/sell/mid/net volume, VWAP, OHLC.
/v1/flow/stocks/{symbol}/cumulative
Running cumulative net stock flow with per-minute VWAP and trade counts.
Cross-symbol scans
Universe-wide scans (cached 30s on the server) for ranking and outlier detection.
/v1/flow/options/leaderboard
Cross-symbol option-flow buyers and sellers ranked by net notional.
/v1/flow/options/outliers
Cross-symbol option-flow outliers ranked by absolute net notional with imbalance, skew, and biggest-trade context.
/v1/flow/stocks/leaderboard
Cross-symbol stock-flow buyers and sellers ranked by net notional.
/v1/flow/stocks/outliers
Cross-symbol stock-flow outliers ranked by absolute net notional.
