Time Zone Box & Alerts (Simplified)

### Description

This Pine Script indicator is designed for TradingView and provides functionality for drawing time-based boxes on the chart, as well as generating alerts and labels. It is particularly useful for visualizing specific time ranges within each trading day and managing alerts based on those time intervals.

#### **Features:**

1. **Box Drawing for Specific Time Ranges**:
- **Time Interval Customization**: Allows users to specify the start and end times for the box using inputs (e.g., from 9:30 AM to 12:30 PM). The box will automatically adjust based on these times.
- **Historical Data**: The script calculates the high and low prices within the specified time range and draws a box accordingly. This box will be created for each trading day, capturing all relevant historical data within the defined time interval.

2. **Dynamic Alerts**:
- **Custom Alerts**: Users can define custom alert messages for specific times within the trading day (e.g., before and after the trading range). Alerts are triggered once per bar close at the specified times.

3. **Labels for Key Time Points**:
- **Customizable Labels**: Labels can be added at specific times to indicate important trading actions (e.g., "No Trade," "Open Trade," and "Close Trade"). The text, color, and size of these labels are customizable.
- **Label Display**: Labels appear on the chart at defined times to provide visual cues for trading decisions.

4. **Visual Customization**:
- **Box and Label Colors**: Users can choose colors for the box and labels to match their preferences or trading setup.
- **Box Transparency**: The box can be customized with varying levels of transparency to enhance chart visibility.

#### **Usage:**

1. **Set Up Time Intervals**: Define the start and end times for the box using the input fields. Adjust these settings to fit your trading strategy and time zones.
2. **Adjust Alerts and Labels**: Customize the alert messages and label text to fit your trading plan.
3. **Apply to Chart**: Add the script to your TradingView chart to visualize the time-based boxes, receive alerts, and see the labels.

This script helps traders visually identify significant time ranges within the trading day and receive timely alerts and labels, enhancing their decision-making process.
