Custom Time Range Highlight

This indicator highlights specific time ranges on your TradingView chart with customizable background colors and labels, making it easier to identify key trading sessions and ICT (Inner Circle Trader) Killzones. It is designed for traders who want to mark important market hours, such as major sessions (Asia, New York, London) or high-volatility Killzones, with full control over activation, timing, colors, and transparency.
Features

Customizable Time Ranges: Define up to 9 different time ranges, including one custom range, three major market sessions (Asia, New York, London), and five ICT Killzones (Asia, NY Open, NY Close, London Open, London Close).
Individual Activation: Enable or disable each time range independently via checkboxes in the settings. By default, only the ICT Killzones are active.
Custom Colors and Transparency: Set unique background and label colors for each range, with adjustable transparency for both.
Labeled Time Ranges: Each active range is marked with a customizable label at the start of the period, displayed above the chart for easy identification.
Priority Handling: If multiple ranges overlap, the range with the higher number (e.g., Asia Killzone over Custom Range) determines the background color.
CET Time Zone: Time ranges are based on Central European Time (CET, Europe/Vienna). Adjust the hours and minutes to match your trading needs.

Settings
The indicator settings are organized into three groups for clarity:

Custom Range: A flexible range (default: 15:30–18:00 CET) for user-defined periods.
Session - Asia, NY, London: Major market sessions (Asia: 01:00–10:00, New York: 14:00–23:00, London: 09:00–18:00 CET).
ICT Killzones - Asia, NY, London: High-volatility periods (NY Open: 13:00–16:00, NY Close: 20:00–23:00, London Open: 08:00–11:00, London Close: 16:00–18:00, Asia: 02:00–05:00 CET).

For each range, you can:

Toggle activation (default: only ICT Killzones enabled).
Adjust start and end times (hours and minutes).
Customize the label text.
Choose background and label colors with transparency levels (0–100).

How to Use

Add the indicator to your chart.
Open the settings to enable/disable specific ranges, adjust their times, or customize colors and labels.
The chart will highlight active time ranges with the selected background colors and display labels at the start of each range.
Use it to focus on key trading periods, such as ICT Killzones for high-probability setups or major sessions for market analysis.

Notes

Ensure your time ranges align with your trading instrument’s session times.
Overlapping ranges prioritize higher-numbered ranges (e.g., Asia Killzone overrides London Session).
Ideal for day traders, scalpers, or ICT strategy followers who need clear visual cues for specific market hours.
