monday & weekend Range

[English Description]
This indicator automatically marks the high and low of the current week's Monday, as well as the high and low of the previous weekend (Saturday/Sunday) on the chart. At the start of each new week, the indicator records the highest and lowest prices of the just-ended weekend and displays them as dashed lines and labels throughout the current week. This helps traders visually identify key support and resistance levels from the previous weekend. The indicator also marks the high and low of the current Monday, making it easier to capture the market's early-week volatility range. This tool is suitable for short-term and swing traders, especially those focusing on weekly reversals, breakouts, and pullback strategies.

Key Features:
Automatically tracks and displays the high and low of the current Monday
Automatically tracks and displays the high and low of the previous weekend
Handles week and year transitions automatically
Visually displays key price levels with dashed lines and labels

Usage Suggestion:
Combine this indicator with your own trading system to use these key price levels as references for support/resistance, breakouts/pullbacks, or range trading strategies.
