Inside Bar Coloring (Real-time + Historical) w/ Alerts

Description
This Pine Script v6 indicator identifies and colors inside bars, whose entire range (high and low) stays within the previous bar's range. It gives the option to color the real-time bar as well as historical inside bars.
Inside bars are colored differently based on whether they close above or below their opening price (bullish vs bearish). The indicator offers flexible display options including real-time-only highlighting, historical inside bar visualization with transparency, and optional triangle markers for enhanced visibility.

Utility
Inside bars represent periods of market consolidation and reduced volatility, and are by nature consolidating. During this equilibrium, it can be valuable to observe price development rather than engage with it. Conversely, a break of the equilibrium often marks a shift in volatility and provides opportunity. This indicator provides instant visual identification of this price action on your chart.
