Sessions: Daily Close, Open, Initial Balance [diJMedia Trading]

What This Script Does
This advanced session indicator displays critical trading levels for intraday traders, focusing on three main components:

Session Open and Close Lines - Tracks the opening and closing prices of your configured trading session
Initial Balance (IB) - Shows the high and low range formed during the first period of the session (configurable duration)
IB Extensions (IBx) - Dynamically displays extension levels above and below the initial balance based on the IB range
Previous Daily Close - Extends the previous session's close level into the current session
Key Features
Customizable Session Configuration: Define your preferred trading session (e.g., New York, London, Asia) with custom time zones
Initial Balance Period: Set the IB duration in minutes (default: 60 minutes)
Dynamic IB Extensions: Automatically calculates and displays IBH1, IBH2, IBH3... (above IB) and IBL1, IBL2, IBL3... (below IB) as price reaches these levels
IB Middle Lines: Optional middle lines between IB levels for precise entry/exit points (requires minimum IB range of 3 points)
High Precision: Uses lower timeframe (1-minute) data for accurate IB calculations
Full Customization: Each line type has independent color, width, and style (solid/dashed/dotted) settings
Session Range Display: Shows the total range in points for each session
How to Use It
Setup:

Add the indicator to your intraday chart (Note: does not work on daily/weekly/monthly timeframes)
Configure your trading session time and timezone in the "Session" settings group

Understanding the Levels:

Open Line (cyan): Session opening price - often acts as support/resistance
Close Line (red): Session closing price - updates in real-time
Daily Close (red): Previous session's close - critical reference level
IB High/Low (blue/red dots): The range established during the initial balance period
IBHx/IBLx (orange): Extension levels measured by the IB range (e.g., IBH1 = IB High + 1 x IB range)
IBM, IBHm, IBLm (purple): Middle lines between IB levels for refined entries
Trading Applications:

Initial Balance Theory: Traders use IB as a measure of volatility; breakouts from IB often indicate trending days
Extension Levels: IBx levels act as natural profit targets and reversal zones
Open/Close Levels: Key support/resistance areas for intraday trading
Previous Daily Close: Essential reference point for gap trading and bias determination
Customization:

Toggle display of each component independently in "Display" settings
Customize colors, line widths, and styles in "Lines" and "Initial Balance" groups
Set maximum number of IBx extension levels (0-10)
Adjust minimum IB range required to display middle lines
Best Practices:

Works best on 5-minute to 60-minute charts
Default 60-minute IB period is standard for equity markets
Adjust IB period based on market volatility (shorter for volatile markets)
Use with volume analysis and price action for confirmation
