This script draws two lines on a chart:
1. **Price Range Lines**: It lets you define a start and end price, then draws horizontal lines at every 100 price units in between.
2. **Opening Lines**: It draws two lines:
- One for the **Midnight Open** (00:00 NY time)
- One for the **08:30 Open** (NY time)
You can customize the color, style, and width of these lines, and optionally add labels showing "Midnight Open" or "08:30 Open". You can also choose the timezone.
In short: It helps visualize key price levels (range) and opening times with customizable lines and labels.
