Presentation of the "Percentile Nearest Rank Without Arrays [CHE]" Indicator
The "Percentile Nearest Rank Without Arrays [CHE]" is a robust trading indicator designed to calculate the percentile value of a specific price within a defined time frame. This indicator provides traders with a visual representation that helps identify market trends and potential turning points.
Key Features and Functions:
- Percentile Calculation: The indicator calculates the percentile of the closing price within a specified period (default length is 15 periods). This allows traders to view the current price in the context of its historical distribution.
- Customizable Parameters: Traders can adjust the length of the observed period and the desired percentile value, making the analysis more tailored to their trading strategies.
- Color-Coded Visualization: The indicator uses color coding to signal whether the current closing price is above (green) or below (red) the calculated percentile value, providing visual clarity and quick decision-making.
- Efficiency Without Arrays: By avoiding the use of arrays, the indicator is more efficient in terms of computation and memory usage. This results in faster performance, especially when dealing with large datasets or real-time data.
Importance for Traders:
1. Trend Identification: By analyzing whether the current price is above or below a specific percentile value, traders can identify trends early and act accordingly.
2. Risk Management: The indicator helps traders better understand volatility and price distribution, leading to more effective risk management.
3. Trading Strategies: It can be used as part of trading strategies to identify entry and exit points based on statistical distributions.
4. Simplicity and Efficiency: As the indicator operates without the use of arrays, it is more efficient and simpler to implement, reducing computation time and improving the performance of the trading platform.
Scientific Explanation of Percentile Nearest Rank:
The Percentile Nearest Rank method is a statistical technique used to determine the relative standing of a value within a data set. For a given dataset of length \( n \) and a desired percentile \( p \), the method follows these steps:
1. Index Calculation: The index corresponding to the desired percentile is calculated using the formula:
index = ( p / 100 n ) -1
where "ceiling" denotes rounding up to the nearest integer.
2. Value Sorting: The values in the dataset are conceptually sorted from smallest to largest.
3. Count Comparison: For each value in the dataset, count how many values are smaller. When the count matches the calculated index, the value at this position is the percentile value.
4. Result Assignment: The value identified as the percentile value is then used for further analysis or plotting.
This method is advantageous for trading because it provides a non-parametric way to understand price distributions, making it less sensitive to outliers and more robust in volatile markets.
Scientific Context and Utility:
- Statistical Robustness: Unlike mean and median, the percentile provides a robust measure of the data distribution, less influenced by extreme values. This robustness is crucial for traders dealing with volatile markets.
- Non-Parametric Analysis: Percentiles do not assume any underlying distribution (e.g., normal distribution) of the data, making the analysis more flexible and broadly applicable.
- Quantitative Decision Making: By using percentiles, traders can make data-driven decisions based on the relative standing of current prices within historical data, enhancing the objectivity of their strategies.
- Efficiency Without Arrays: Avoiding the use of arrays reduces memory consumption and computational overhead, making the indicator more suitable for real-time applications and large datasets. This improves overall performance and responsiveness on trading platforms, which is crucial for making timely trading decisions.
In summary, the "Percentile Nearest Rank Without Arrays [CHE]" indicator is a powerful tool for traders seeking to integrate statistical price distribution insights into their trading strategies. It provides a robust, non-parametric, and visually intuitive method to analyze market trends and volatility, while offering enhanced computational efficiency by avoiding the use of arrays.

Changes in This Script Version:Added Candle Count Parameter: Introduced a new input parameter candles to specify the number of candles to wait after a crossover before changing the color. This adds more flexibility and precision to the indicator's behavior.
Color and State Variables: Introduced variables current_color, above_pnr_count, and below_pnr_count to keep track of the current color state and the number of bars above or below the percentile value.
Crossover Detection: Added logic to detect when the price crosses above or below the percentile value. This includes counting the number of consecutive candles above or below the percentile before changing the color.
Color Logic Enhancement: Enhanced the color logic to change the plot color to green or red only after the price has remained above or below the percentile value for the specified number of candles. If neither condition is met, the color remains gray.
These improvements enhance the indicator by providing a more precise and configurable visual representation of price behavior relative to the calculated percentile, making it more useful for traders in identifying sustained trends and making informed trading decisions.
