Previous Day Max 15-Mins Move High/Low

Introduction
This TradingView script is designed to help traders quickly identify significant price movement levels from the previous trading day based on the 15-minute time frame. It finds the largest high-to-low range of any 15-minute candle from the prior day and draws horizontal lines at those levels. These levels can help traders set potential support and resistance zones, aiding in intraday trading decisions and market analysis.

In many trading strategies, significant levels from previous sessions are crucial for determining potential support and resistance points. By identifying the largest price move from the prior day’s 15-minute candles, this script can highlight areas of market interest where volatility was at its highest. Traders can use these levels to:

Anticipate potential reversal points.
Plan entries and exits based on key support and resistance.
Gauge market sentiment by observing how the price reacts to these levels during the current session.
This can be especially valuable in fast-paced trading environments or when analyzing shorter time frames. The lines extend across all time frames, so you can use this script on higher time frames as well to see previous-day levels while zooming out.
