On 2 August 2026 the RadarPulse confluence board paired invented options prints with genuine STOCK Act disclosures and put a confidence number on the result. What it did, why it happened, exactly what changed, and two commands you can run to check the fix yourself. Read →
Complete code examples for wiring options flow alerts into Discord bots, Slack channels, and custom systems via HMAC-signed webhooks, including signature verification, deduplication, score-based filtering, and a SQLite signal logger for backtesting. Read →
An honest answer by trading style: who benefits from paying for options flow data, who doesn't, how to evaluate signal quality with a paper-trade trial, and the six workflow questions you should answer before subscribing. Read →
A buyer's framework for evaluating options flow scanners: data latency verification, composite scoring standards, alert speed, contextual enrichment (Congress overlap, sector confluence), and the 6 questions to ask before paying for any tool. Read →
What a 15-minute delay actually costs you in options flow: which signals survive it, which don't, how to verify any provider's real data latency, and how to use delayed flow intelligently when real-time isn't available. Read →
A Python implementation guide for building a DIY options flow scanner: data sources, correct Vol/OI computation, sweep detection, composite scoring, and the honest cost comparison between building from scratch vs. using an API. Read →
What historical flow datasets actually contain, how to build a rigorous backtest (with Python), what directional hit-rates to honestly expect by tier, and why almost no tools publish their track records. Read →
REST vs WebSocket, the 8 data fields that actually matter (premium, sweep, Vol/OI, ask-side fill), a Python Discord bot example, webhook HMAC verification, and how to choose a provider. Read →
Five filters that actually matter (premium floor, sweep type, Vol/OI, DTE, ask-side fill), how to read screener output row by row, common mistakes, and a full morning-to-close workflow. Read →
A frank breakdown of three data tiers: free/sample, 15-min delayed (~$29/mo), and real-time ($99–200/mo), with use-case tables showing exactly when each tier is adequate and when it isn't. Read →
