Calculation notes
- Shows momentum and whether Bollinger Bands lie strictly inside an EMA and Wilder ATR Keltner channel. A release marks the end of compression, without predicting direction. This TraderAI variant differs from the original Keltner channel used by StockCharts. Gaps restart calculation; the current bar can change.
