Bullflow

by Bullflow LLC

Overview

Use Bullflow in ChatGPT to research options activity and manage your saved custom alerts. Explore leading options tickers, net premium, gamma and vanna exposure, dark pool trades, and trade prices. Compare returned observations with their dates, timestamps, and filters, or create a custom alert using criteria you specify. Requires an existing Bullflow account with an active API subscription. Connect through Bullflow OAuth and approve the requested permissions. The plugin supports market research and alerts; it does not execute trades, manage brokerage accounts, or sell subscriptions. Market observations are for informational purposes and do not guarantee future results.

Tools

bullflow_api_docs

ChatGPT

Return Bullflow public API docs, endpoint parameters, auth guidance, and MCP connection details.

bullflow_backtesting_replay_sample

ChatGPT

Collect a bounded sample from /v1/streaming/backtesting for coding agents. This does not connect to the live alerts stream.

bullflow_create_alert

ChatGPT

Create a saved custom alert for the connected subscriber account using clean flat field names.

bullflow_dark_pool_trades

ChatGPT

Retrieve a paginated list of dark-pool trades for an inclusive date range of up to 30 days, optionally filtered by ticker and minimum notional value in US dollars. Returns trade symbols, prices, share sizes, notionals, and available report timestamps, plus a next-page cursor. Each response is one page, not a complete total for the date range.

bullflow_eod_gex

ChatGPT

Look up an end-of-day gamma exposure snapshot for an underlying ticker and optional YYYY-MM-DD trading date. Omit date for the latest eligible session; a session becomes eligible after 17:15 America/New_York. Uses closing gamma and underlying price with the open interest reported for that session, representing the previous trading day's close (open_interest_date). Returns ticker, date, open_interest_date, timezone, spot_price, as_of in UTC, and strike/expiration rows with call_gex, put_gex, and net_gex. GEX is in USD per 1% underlying move: gamma times open interest times 100 times spot_price squared times 0.01. Calls are positive and puts negative. Expirations before the requested date are excluded. Limit: 10 requests per rolling 60 seconds per credential or payer. No snapshot returns HTTP 404.

bullflow_get_custom_alerts

ChatGPT

Return saved custom alerts for the connected subscriber account.

bullflow_gex_alerts

ChatGPT

Read current or historical closest-expiration GEX proximity and node movement alerts. Defaults to the current U.S. Eastern date. Results are paginated; use nextCursor with the same filters for more alerts.

bullflow_historical_options_flow

ChatGPT

Read recorded historical options trades for one date or an inclusive range of up to 30 calendar days. Filter by ticker, contract, call/put, trade type, execution side, premium, size, or minimum SigScore. Cancelled trades are excluded. Results are newest first and each response is one page; pass nextCursor with the same filters to continue.

bullflow_last_trade_price

ChatGPT

Look up the latest available trade price for a stock, ETF, or index ticker, such as SPY or SPX. Returns the price in US dollars and a trade timestamp when available. Use it for a latest-price lookup, not historical price bars.

bullflow_live_options_flow_endpoint

ChatGPT

Get the SSE URL, authentication guidance, event types, and trade fields for live options flow. The stream delivers newly published trades after connection, switches trading dates at midnight U.S. Eastern time, and sends heartbeats every 10 seconds. Requires an active API subscription; reconnecting does not replay missed trades.

bullflow_net_gex

ChatGPT

Look up net gamma exposure (GEX) by option strike and expiration for an underlying ticker. Omit type or use type=oi for open-interest weighting; use type=volume for cumulative contract volume from the current or most recent U.S. Eastern trading day. Returns calculated call_gex, put_gex, net_gex, call_gamma, put_gamma, spot_price, and as_of. GEX uses a 1% underlying-price move; gamma fields use the selected contract count multiplied by 100. Calls contribute positively and puts negatively. Contracts with no volume in the selected session contribute zero; no matching volume returns an empty strikes array. Unavailable volume returns HTTP 503. Both modes share the endpoint's 25 requests per rolling 60 seconds limit. Gamma and spot calculations refresh approximately every 5 seconds. Volume mode uses the latest available cumulative contract volume for the current or most recent U.S. Eastern trading day. Before a new session has volume, and on weekends or holidays, it uses the most recent completed trading day. Check as_of for the gamma and spot calculation timestamp.

bullflow_net_premium_series

ChatGPT

Return cumulative call and put net premium values for a ticker and date range.

bullflow_net_vex

ChatGPT

Look up net vanna exposure (VEX) for an underlying ticker. Returns call, put, and net vanna exposure by option strike and expiration, along with the underlying spot price and as-of timestamp. Use it to examine how vanna exposure is distributed across strikes and expirations. Results are cached for 5 seconds per ticker. Repeated requests within that window may return the same calculation; the next request after expiry recalculates using the latest available data. Check as_of for the calculation timestamp.

bullflow_open_research

ChatGPT

Open interactive Bullflow market research to browse options leaders, filter historical options flow and dark-pool trades, and explore a ticker's activity profile, net premium, and gamma exposure. Use Bullflow data tools for market-data questions that do not need an interactive view.

bullflow_open_workspace

ChatGPT

bullflow_options_profile

ChatGPT

Summarize recorded Bullflow options activity for one ticker in the latest available session: call/put volume, full-day and same-Eastern-time relative volume against the prior 20 available trading dates, premium, ask-side percentages, sweeps, 0–7-day concentration, unusual contracts, and structured flags. Coverage is recorded flow, not complete market-wide volume. Ratios are null with insufficient history or a zero denominator. Directional premium excludes multi-leg trades. Check tradingDate, asOf, and flags before interpreting the result. Allows 10 requests per rolling 60 seconds.

bullflow_options_top_tickers

ChatGPT

Return leading option-flow tickers for a selected volume, premium, or net-premium view.

bullflow_peak_return

ChatGPT

Look up the highest historical option price reached after a supplied trade timestamp and its percentage return relative to the supplied entry price. Provide the option contract symbol, entry price, and trade timestamp. Returns the peak price in US dollars and peak percentage return; this is historical performance, not a forecast.
