ICT Kill Zone & SNR Tool

7月16日

## Features

- **Auto-Draws Key Price Lines:**\
Plots the close price line for both the current timeframe and a higher timeframe (HTF) of your choice. The HTF close line helps you identify major support/resistance (SNR) areas from higher timeframe structure. All lines are managed automatically to keep the chart clear.

- **Kill Zone Session Markers:**\
Automatically highlights four key Kill Zone trading sessions (London, New York, London Close, Asia) according to ICT concepts. Kill Zone time windows are adjusted for your chart's timezone, with colored horizontal lines and center labels. If any major economic event overlaps with a Kill Zone, a 🔥 icon will be added to its label.

- **Real-Time Economic Calendar Integration:**\
Integrates TradingView's EconomicCalendar library to display major macroeconomic events (FOMC, CPI, PPI, NFP, etc.) directly on your chart. Events are matched to each bar in real time and checked for overlap with Kill Zone periods.

## How to Use

1. **Enable/Disable Elements:**\
Use the settings panel to turn on/off the close price lines for the current and higher timeframe, and adjust color/width as needed.

2. **Select HTF (Higher Timeframe):**\
Choose the desired higher timeframe (such as 1H, 4H, D). The HTF close line updates only when its value changes.

3. **Configure Kill Zones:**

- Toggle Kill Zone markers and select line style (solid, dashed, dotted).
- Set custom names for each session if needed.
- All time calculations are auto-adjusted for your chart's timezone.
4. **Economic Events:**

- Select which event types (FOMC, CPI, NFP, etc.) you want to show.
- When a Kill Zone period contains an economic event, a 🔥 icon is shown in the label for extra caution.
- Hidden event icons are also plotted on bars for backtesting reference.
5. **Chart Clarity:**\
The script automatically limits the number of lines/labels plotted to keep the chart clear and readable.

## How it Works

- **Close Line Drawing:**\
Draws a line from the previous close to the current close for each bar; HTF line only updates when the HTF close changes.

- **Kill Zone Detection:**\
Converts NY Kill Zone session times to your local timezone. For each session, detects entry/exit, draws a colored horizontal line and a centered label.

- **Economic Event Overlay:**\
Checks all selected economic events and overlays a 🔥 to session labels if they overlap; optionally plots an icon on the event bar.
