How this page works — sector ETF signals, formulas and data source
What it is. The same technical scoring as the front-page orbs, applied to theCommunication Services Select Sector SPDR (XLC) itself: Money Flow Index (14d), 20-day relative strength vs SPY, and 20-day volume pressure. Colors and the BUY / CONTINUATION confirmation rule are identical to the sector orbs.
Win-rate table. Shows how often this ETF's own historical B / C signals were followed by a rise over each horizon, computed on ~28 years of daily data with no look-ahead (consecutive signal days count once; exit at close of day t+20). Context, not proof — read the numbers together with n.
Data source. Daily OHLCV from Yahoo Finance (adjusted for splits/dividends), recomputed after every US market close. Not investment advice — seethe disclaimer.
