BB% Crossing Bollinger Bands Alerts

This script focuses exclusively on the behavior of the BB% indicator. It signals a SELL alert when the BB% value crosses upward through 1.0 (meaning it has breached the top Bollinger Band) and a BUY alert when the BB% crosses downward through 0.0 (meaning it has fallen below the bottom Bollinger Band). The script is fully customizable through its inputs and provides clear visual indicators alongside conditions you can use to trigger alerts on TradingView.
