Sector Pullback Watch

Sector Pullback Watch scores a configurable universe of ETFs or stocks against a fixed rule set every session — pullback setups, two kinds of trend start, continuation, recovery bounces, trend-end risk — and renders the result as a single HTML file with no JS dependencies and no external requests, so it works offline and can be emailed as-is. Indicators are computed locally from a cached OHLCV file, which means no per-symbol API calls at score time and no indicator vendor. The bundled fetcher uses Yahoo and needs no account; swapping in a broker API is one CSV away. It also tries to be honest in a way these tools usually aren’t. Every base rate on the page carries its provenance — one in-sample study, 10 ETFs, no costs, no holdout — and is framed against the 67% baseline you get from simply being above the 200-day, so “70%” reads as three points of margin rather than a win rate. Instruments outside that sample are flagged as unvalidated at runtime. It’s a tool for deciding where to spend attention, not a strategy.
