Near 0% means it is at recent highs; -15% means 15% below that high. → https://stock-compass.app/en/glossary/distance-from-20-day-high+ - **Vol Ratio** (vol_vs_avg20d): Today's trading volume as a multiple of the 20-day average. 1.0x is normal; above 1.5x means attention suddenly spiked (news or money moving). → https://stock-compass.app/en/glossary/relative-volume+ - **Relative Strength (RS)** (relative_strength): Roughly one month of price change minus the benchmark's change over the same window (in pp). Positive means it outpaced the index, negative means it lagged. → https://stock-compass.app/en/glossary/relative-strength+ - **MACD** (macd_hist): Reads momentum from the gap between the 12 and 26-day exponential averages (DIF) and its 9-day average (DEA). DIF crossing above DEA is a golden cross; the histogram is their difference, and only its sign compares across stocks. → https://stock-compass.app/en/glossary/macd+ - **Moving averages (MA20 / MA50 / MA200)** (price_vs_ma20): The average close of the last 20, 50 and 200 trading days: the short, medium and long-term trend. Price above an average means it is above its average over that period; averages always lag price. → https://stock-compass.app/en/glossary/moving-averages+ - **KDJ** (kdj_k): Where the close sits within the last nine days' high-low range, from 0 to 100. Below 20 is usually called oversold and above 80 overbought; in a strong trend it can stay high for weeks. → https://stock-compass.app/en/glossary/kdj+ - **Bollinger Band position** (price_vs_bb_lower): How far the price is above the lower Bollinger Band (the 20-day average minus two standard deviations). Zero is on the band, negative is below it: low against its own last 20 days, which is not a promise of a bounce. → https://stock-compass.app/en/glossary/bollinger-bands
