Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Quant Data
Measured market statistics for equities, index futures and options positioning: rolling Brooks price-action events with pre-registered outcome rates plus a calibrated day-type probability read and an arithmetic shape description, Weis volume-price wave events with pre-registered win rates, options max pain computed from open interest alone, and estimated dealer gamma exposure — plus free, key-less max pain and GEX pages. Reports honest numbers with their baselines and refuses to turn them into trading advice.
Open Markets
Financial market data, SEC filings, macroeconomic telemetry, and portfolio analytics through MCP.
