# Price crosses Bollinger Bands

Any way to take this script and take out the RSI portion? Just need the indicator to signal when price crosses or touches the upper or lower Bollinger Bands regardless of what RSI is. Price does not have to close above/below the bands, just needs to cross or touch them. Any help would be greatly appreciated!
