Mis à jour Prior Day Range Box

Prior Day Range Box
Prior Day Range Box plots the previous trading day’s high and low directly on the current chart and displays that range as a visual box with optional reference lines. The script pulls the prior day’s high and low from the daily timeframe, then projects those levels onto the active chart so traders can track how current price behaves around important higher-timeframe levels.
At the start of each new trading day, the indicator creates a new prior day range using the previous day’s high and low. A box can be drawn between those levels to clearly show the full prior day range, while separate horizontal lines mark the prior day high and prior day low. These levels are widely used by intraday traders as key areas for support, resistance, breakout confirmation, rejection, and liquidity interaction.
An optional midpoint line can also be displayed. This line marks the 50% level of the prior day’s range and can serve as an added reference for balance, mean reversion, or directional bias during the session.
The script also includes an optional historical lookback mode. When enabled, it can display prior day range levels from multiple past sessions, making it easier to study how price reacts to historical daily ranges over time. The number of displayed lookback days can be adjusted to fit the user’s preference.
All visual elements are customizable. Users can choose whether to show the range box, enable the midpoint, extend the prior day high and low across the chart, display historical lookback days, and adjust the colors and line width to match their chart setup.
This indicator is designed for traders who use prior day high and low levels as part of their intraday process and want a clean visual framework for tracking previous session range structure on any intraday chart.
