Download script
This script is a technical analysis tool designed for the MetaTrader platform. It automates the monitoring of market momentum by calculating specific Moving Average Convergence Divergence (MACD) values and identifying key trading moments based on how these values interact with each other.
Instead of requiring you to watch charts constantly, the script scans price data and generates visual signals (arrows) and audible alerts when specific conditions are met.
Core Logic Overview
The tool operates by comparing two different moving averages—a "Fast" one and a "Slow" one—to determine the overall trend of the market. By subtracting the slow average from the fast average, it creates a momentum line. The script then looks for three specific types of interactions:
1. Primary Trend Shifts (Zero-Line Crosses) The script monitors when the momentum line crosses above or below the zero level.
- Buy Signal: Triggered when the momentum moves from negative to positive.
- Sell Signal: Triggered when the momentum moves from positive to negative.
2. Momentum Strength Signals (Signal Line Crosses) The script also calculates a "Signal Line" (an average of the momentum itself). It looks for instances where the momentum line crosses this signal line while maintaining a specific position relative to zero.
- Enhanced Buy: Triggered when the momentum is positive and crosses above its signal line.
- Enhanced Sell: Triggered when the momentum is negative and crosses below its signal line.
3. Exit Opportunities The tool identifies points where the current trend might be losing steam, providing visual cues to consider closing an open position.
- Exit Long: Triggered when the momentum is positive but crosses under the signal line.
- Exit Short: Triggered when the momentum is negative but crosses over the signal line.
User Interface and Alerts
To make these signals actionable, the script provides the following features:
- Visual Indicators: It places different types of arrows on your chart to distinguish between primary entries, secondary momentum shifts, and exit points.
- Dynamic Alerting: You can enable "Alerts" (pop-up windows) and "Sounds" to notify you the moment a signal appears.
- Dual-State Monitoring: The script is designed to check for signals on two different states of a candle: the "Live" candle (currently forming) and the "Closed" candle (the most recently completed price action). You can choose to receive notifications for either or both.
- Customizable Smoothing: The logic allows for various types of moving average calculations (such as Simple, Exponential, Smoothed, or Linear Weighted), giving you the flexibility to tune the sensitivity of the signals to match different trading styles.
