Swing Identifier

18 ene

The "Swing Identifier" is a custom Pine Script indicator designed for use in the TradingView platform. It serves to visually identify and mark swing highs and swing lows on a trading chart, which are key concepts in technical analysis. This script is comprehensive and customizable, making it a useful tool for traders looking to pinpoint potential trend reversals and support or resistance areas.

**Key Features of the 'Swing Identifier' Indicator:**

1. **Swing Range Input:**
- This input determines the number of bars to the left and right of the current bar that the script will examine to identify a swing high or low. A larger value will look for swings over a broader range, potentially identifying more significant swings but at the expense of sensitivity.

2. **Swing Strength Input:**
- The swing strength is set as a percentage and is used to filter out insignificant price movements. A swing high or low is only considered valid if the percentage change from the last swing is greater than this input value. This feature helps in avoiding false signals in sideways or less volatile markets.

3. **Use Wicks Option:**
- Users can choose whether to consider the wicks of the candles or just the closing prices in identifying swings. This feature adds flexibility, allowing the script to be tailored to different trading styles and strategies.

4. **Line Color Customization:**
- The color of the lines marking the swings can be customized, enhancing the visual appeal and readability of the chart.

**Operational Mechanics:**

1. **Identification of Swing Highs and Lows:**
- The script uses the `ta.pivothigh` and `ta.pivotlow` functions to identify swing highs and lows. Whether it uses the high/low of the candles or their closing prices is determined by the user's choice in the "Use Wicks" option.

2. **Drawing and Updating Lines:**
- When a new swing high or low is identified, and it meets the percentage change criteria from the previous swing, a line is drawn from the last swing low to the current high (or vice versa). If a new swing high (or low) is identified that is higher (or lower) than the previous one, the old line is deleted, and a new line is drawn.

3. **Swing Update Logic:**
- The script maintains a toggle mechanism to look alternatively for highs and lows. This ensures that it sequentially identifies a high and then a low (or vice versa), which aligns with how actual market swings behave.

**Usage in Trading:**

1. **Identifying Trend Reversals:**
- By marking swing highs and lows, the script helps traders identify potential trend reversals. A break of a swing low in an uptrend or a swing high in a downtrend could signal a change in the prevailing trend.

2. **Support and Resistance:**
- Swing highs and lows often act as levels of support and resistance. Traders can use these levels for setting entry or exit points, stop losses, and take profit orders.

3. **Customization for Strategy:**
- The customizable nature of the script allows traders to adjust the parameters according to their trading strategy, time frame, and asset volatility.

In summary, the "Swing Identifier" is a versatile and customizable tool that aids in visually identifying crucial price swing points, thereby assisting traders in making informed decisions based on technical analysis principles.
