Multi-Length RSI

8月30日 **Multi-Length RSI Indicator**

This script creates a custom Relative Strength Index (RSI) indicator with the ability to plot three different RSI lengths on the same chart, allowing traders to analyze momentum across various timeframes simultaneously. The script also includes features to enhance visual clarity and usability.

**Key Features:**

1. **Customizable RSI Lengths:**
- The script allows you to input and customize three different RSI lengths (7, 14, and 28 by default) via user inputs. This flexibility enables you to track short-term, medium-term, and long-term momentum in the market.

2. **Dynamic Colour Coding:**
- The RSI lines are color-coded based on their current value:
- **Above 70 (Overbought)**: The line turns red.
- **Below 30 (Oversold)**: The line turns green.
- **Between 30 and 70**: The line retains its user-defined colour (blue, yellow, orange by default).
- This dynamic colouring helps to quickly identify overbought and oversold conditions.

3. **Adjustable Line Widths and Colours:**
- Users can customize the colour and thickness of each RSI line, allowing for a personalized visual experience that fits different trading strategies.

4. **Overbought, Oversold, and Midline Levels:**
- The script includes static horizontal lines at the 70 (Overbought) and 30 (Oversold) levels, with a red and green colour, respectively.
- A midline at the 50 level is also included in gray and dashed, helping to visualize the neutral zone.

5. **Dynamic RSI Value Labels:**
- The current values of each RSI line are displayed directly on the chart as labels at the most recent bar, with colours matching their corresponding lines. This feature provides an immediate reference to the exact RSI values without the need to hover or look at the data window.

6. **Alerts for Crosses:**
- The script includes built-in alert conditions for when any of the RSI values cross above the overbought level (70) or below the oversold level (30). These alerts can be configured to notify you in real-time when significant momentum shifts occur.

**How to Use:**

1. **Customization**:
- Input your preferred RSI lengths, colours, and line widths through the script’s settings menu.

2. **Visual Analysis**:
- The indicator plots all three RSI values on a separate pane below the price chart. Use the color-coded lines and levels to quickly identify overbought, oversold, and neutral conditions across multiple timeframes.

3. **Set Alerts**:
- You can configure alerts based on the built-in alert conditions to get notified when the RSI crosses critical levels.

**Ideal For:**

- **Traders looking to analyze momentum across multiple timeframes**: The ability to view short-term, medium-term, and long-term RSIs simultaneously offers a comprehensive view of market strength.
- **Those who prefer visual clarity**: The dynamic colouring, clear labels, and customizable settings make it easy to interpret RSI data at a glance.
- **Traders who rely on alerts**: The built-in alert system allows for proactive trading based on significant RSI level crossings.
