Previous 2 Days High/LowCan you give me a summary of this indicator
The "Previous 2 Days High/Low" indicator, written in Pine Script v5 for TradingView, plots horizontal lines representing the combined high and low prices of the previous two trading days on a chart. Here's a summary of its functionality, purpose, and key features:
Purpose
The indicator helps traders identify significant price levels by displaying the highest high and lowest low from the previous two days, which can act as potential support or resistance levels. These levels are plotted as lines that extend across the current trading day, making it easier to visualize key price zones for trading decisions.
Key Features
Calculates Combined High and Low:
Retrieves the high and low prices of the previous day and the day before using request.security on the daily timeframe ("D").
Computes the combined high as the maximum of the two days' highs and the combined low as the minimum of the two days' lows.
Dynamic Line Plotting:
Draws two horizontal lines:
Red Line: Represents the combined high, plotted at the highest price of the previous two days.
Green Line: Represents the combined low, plotted at the lowest price of the previous two days.
Lines are created at the start of a new trading day and extended to the right edge of the chart using line.set_x2, ensuring they span the entire current day.
Labels for Clarity:
Adds labels to the right of the chart, displaying the exact price values of the combined high ("Combined High: ") and combined low ("Combined Low: ").
Labels are updated to move with the lines, maintaining alignment at the current bar.
Clutter Prevention:
Deletes old lines and labels at the start of each new trading day to avoid overlapping or excessive objects on the chart.
Dynamic Requests:
Uses dynamic_requests=true in the indicator() function to allow request.security calls within conditional blocks (if ta.change(time("D"))), enabling daily data retrieval within the script's logic.
