Percent Change of Range Candles
📌 Indicator Description: "Percent Change of Range Candles"
This indicator is designed to visualize the percentage price change over a specified number of candles, relative to the historical market range. Instead of traditional candles, it uses a custom "range candle" visualization that reflects relative changes in context with the highest and lowest points within a given period.
🎯 Purpose and Application
The goal of this indicator is to:
Show how much the current price has changed compared to the price length candles ago (default: 100).
Express this change as a percentage of the total price range during that period.
Help traders identify extreme price movements, whether bullish or bearish.
Serve as an additional filter for momentum zones, divergences, or overextended conditions.
⚙️ How It Works
🔹 Core Calculation:
Range: The difference between the highest and lowest price over the selected period (length).
Price Change: The difference between the current close and the close length bars ago.
Percentage Value: (price_change / range) * 100
🔹 Additional Logic:
The synthetic open value is calculated as the average of the last 5 c values.
The high and low of each range candle are adjusted:
If c is negative, the high is replaced with a shorter-term percentage change (25% of length).
If c is positive, the low is adjusted in the same way.
🔹 Visualization:
Displays custom candles based on percentage change, not real price.
Candle color is green if the current value is above the recent average, and red if below.
Horizontal reference lines are drawn at +100, +70, 0, -70, and -100, helping to identify extremes.
✅ Advantages and Use Cases
Detects market extremes and potential reversal zones.
Useful in volatility or momentum-based strategies.
Can serve as a signal filter or divergence detector when combined with other tools (e.g., RSI, MACD).
