Days of the week

// This indicator is an alternative version of the popular "Days of Week" script originally created by @BALine.
//This version preserves the core functionality while introducing some slight changes:
//Optimized Code Structure: The original seven repetitive plotchar calls for day labels have been replaced with a single, efficient call utilizing a switch statement, resulting in cleaner and more performant Pine Script code.
//Flexible Day Separation: A vertical line is drawn on the chart to clearly mark the beginning of a new trading day, defaulting to the critical 17:00 (5 PM) New York time session rollover (standard for FX and futures).
//Customizable Label Time: The hour at which the day-of-week labels ("Monday," "Tuesday," etc.) appear on the chart is now controlled by a user input, allowing traders to align the label with their local time zone, a specific market open (e.g., 9:00 AM), or any other relevant hourly mark.
//This tool is essential for traders who incorporate time and daily structure into their analysis. It provides an immediate visual reference for daily trading ranges, market session breaks, and identifying day-of-week biases.
//Attribution: A huge thank you to BAline for the original concept and foundation of the "Days of Week" indicator.
