Bullflow

Multi-Tool Platform — Paid

Options flow, dark pool and gamma exposure terminal with an API and MCP server

MCP server access on the API plan so coding agents can query flow and GEX data

Overview

Bullflow is an options flow, dark pool, and gamma exposure terminal built for retail traders who want to see where big money is positioning. This Bullflow review covers a multi-tool platform that streams sweeps and blocks on a live flow dashboard, maps dealer gamma across strikes and expirations with bubble charts and heatmaps, and ships as a web terminal plus iOS and Android apps for traders who want that data on the go.

Bullflow lets you backtest historical flow alerts and check their peak returns, so you're not trusting a signal blind; you can see how similar alerts performed before acting on the next one. Algo alerts flag high-probability setups out of unusual options activity, and a Public brokerage integration lets you place orders straight from the dashboard instead of switching between apps. For developers, a full API exposes alert and GEX endpoints, and the top tier even includes an MCP server so coding agents can query flow and gamma exposure data directly.

The cons are straightforward. Bullflow does not offer a free trial at any tier, so you're paying before you know if the signals actually fit your style. Dark pool data, one of the platform's more distinctive datasets, sits behind the $49 Premium plan rather than the entry tier, so casual users get flow and GEX tools but not the full picture of institutional activity.

Coverage is US stocks only, aimed at day trading and swing trading at an intermediate skill level, with a semi-automated feel thanks to algo alerts and brokerage order entry. Starting price is $33/mo billed yearly, and the $99 API tier with MCP server access makes this genuinely useful for traders building their own automated systems on top of options flow data. Beginners who don't yet understand options flow, and anyone unwilling to commit to a paid plan without testing it first, should hold off.
