Open Range Tool

6月14日

**Open Range Tool --- Session-Based Opening Range Indicator**

A lightweight utility that instantly plots the opening range for a selected session (Asia, London, or New York) on any timeframe, including an optional 0.5 σ mid-line to highlight the session's mean price.

### Key Features

1. **Multi-session support**

- Instantly draw Asia, London, or NY opening ranges on the chart.
2. **Intraday-only display**

- The range is plotted *only for the current trading day* and automatically cleared on the next session, keeping historical charts uncluttered.
3. **Flexible range anchors**

- Define the range by the first candle's **High/Low** *or* **Open/Close**.
4. **Delayed plotting**

- Start plotting after *N* candles to avoid gaps or early noise.
5. **Statistical mid-line & range projection**

- Built-in 50 % mid-line with adjustable projection length (bars).
6. **Full styling control**

- Customize colors, line style, and width for high, low, and mid-lines.

### How to Use

1. Add the indicator to your chart and open the **Inputs** tab.
2. Set **Opening-Range Timeframe** (e.g., 30 min) and choose any **Delay Bars** or **Projection Length** you need.
3. Tweak the line colors/widths to match your chart theme.
4. Combine with volume profile, VWAP, or moving averages for better context.

- New: Support for dynamically calculating the length of the K-bar to be extended based on the current time frame. The basic time frame uses 15 minutes as the calculation unit for the number of K-bar extensions (assuming: set to extend 4 K-bars, and the current time frame is a 5-minute chart, the actual number of K-bars extended will be 12 5-minute K-bars)
