Download script
This technical script is designed to analyze price movements on a trading chart to identify specific trend reversals. Instead of relying on basic price movement alone, the logic uses a combination of volatility measurements, momentum tracking, and price "gaps" to determine when a market move has lost its strength and is likely to turn around.
Core Logic Overview
The script functions by scanning historical data to calculate the "normal" behavior of a currency or asset at any given moment. It achieves this through three primary layers of analysis:
1. Volatility and Range Analysis The tool first measures the average size of price bars over a short period. This establishes a baseline for what constitutes a "normal" move in the current market environment. By understanding this average range, the script can distinguish between standard market noise and significant, out-of-ordinary price swings.
2. Momentum and Breakout Detection The script then looks for specific types of aggressive movements:
- Gap Identification: It checks if there is a sudden jump in price that exceeds twice the average range.
- Rapid Trend Analysis: It monitors whether the price is moving significantly faster than usual over a series of bars. If these aggressive moves occur, the script adjusts its internal sensitivity settings to better account for high-volatility environments.
3. Oscillator Integration and Reversal Tracking To decide on a specific entry signal, the tool utilizes a momentum oscillator (the Will Rogers Principle or similar logic). It looks for specific "overbought" or "oversold" conditions:
- The Oversold Signal: If the momentum drops below a certain threshold, the script searches forward to see if the price stays in that zone or begins to bounce back. If it detects a recovery from an extreme low, it identifies a potential BUY opportunity.
- The Overbought Signal: Conversely, if momentum climbs above a high threshold and then starts to drop, the script identifies a potential SELL opportunity.
Visual Feedback and Alerts
When the logic confirms that a trend has reached an extreme point and is beginning to reverse:
- Visual Markers: The script places specific arrows on the chart (Aqua for Buy signals, Magenta for Sell signals) to highlight where the trend change was detected.
- Real-Time Notifications: The script includes an automated alert system that triggers a notification on your screen when a new signal appears on the most recent live candle, ensuring you can react immediately to potential market turns.
