ICT MACROS (UTC-4)

This Pine Script creates an indicator that draws vertical lines on a TradingView chart to mark specific time intervals during the day. It allows the user to see when certain predefined time periods start and end, using vertical lines of different colors. The script is designed to work with time frames aligned to the UTC-4 timezone.

### Key Features of the Script

1. **Vertical Line Drawing Function**:
- The script uses a custom function, `draw_vertical_line`, to draw vertical lines at specific times.
- This function takes four parameters:
- `specificTime`: The specific timestamp when the vertical line should be drawn.
- `lineColor`: The color of the vertical line.
- `labelText`: The text label for the line (used internally for debugging purposes).
- `adjustment_minutes`: An integer value that allows time adjustment (in minutes) to make the lines align more accurately with the chart’s candles.
- The function calculates an adjusted time using the `adjustment_minutes` parameter and checks if the current time (`time`) falls within a 3-minute range of the adjusted time. If it does, it draws a vertical line.

2. **User Input for Time Adjustment**:
- The `adjustment_minutes` input allows users to fine-tune the appearance of the lines by shifting them slightly forward or backward in time to ensure they align with the chart candles. This is useful because of potential minor discrepancies between the script’s timestamps and the chart’s actual candle times.

3. **Predefined Time Intervals**:
- The script specifies six different time intervals (using the UTC-4 timezone) and draws vertical lines to mark the start and end of each interval:
- **First interval**: 8:50 - 9:10 AM
- **Second interval**: 9:50 - 10:10 AM
- **Third interval**: 10:50 - 11:10 AM
- **Fourth interval**: 13:10 - 13:40 PM
- **Fifth interval**: 14:50 - 15:10 PM
- **Sixth interval**: 15:15 - 15:45 PM
- For each interval, there are two timestamps: the start time and the end time. The script draws a green vertical line for the start and a red vertical line for the end.

4. **Line Drawing Logic**:
- For each time interval, the script calculates the timestamp using the `timestamp()` function with the specified time in UTC-4.
- The `draw_vertical_line` function is called twice for each interval: once for the start time (with a green line) and once for the end time (with a red line).

5. **Visual Overlay**:
- The script uses the `overlay=true` setting, which means that the vertical lines are drawn directly on top of the existing price chart. This helps in visually identifying the specific time intervals without cluttering the chart.

### Summary

This Pine Script is designed for traders or analysts who want to visualize specific time intervals directly on their TradingView charts. It provides a customizable way to highlight these intervals using vertical lines, making it easier to analyze price action or trading volume during key times of the day. The `adjustment_minutes` input adds flexibility to align these lines accurately with chart data.
