wajdyss_MA_indicator_v2

This tool is designed as a visual trading indicator for the MetaTrader platform. It primary functions by identifying specific momentum shifts in the market through "Moving Average" crossovers and provides automated alerts to help traders identify potential entry or exit points.

Core Technical Logic

1. Moving Average Crossings The logic centers on the relationship between two different moving averages: a "Fast" one (which reacts quickly to price changes) and a "Slow" one (which represents the broader trend).

  • Buy Signal: When the Fast Moving Average crosses above the Slow Moving Average, it suggests upward momentum. The script places a visual marker on the chart below the candle.
  • Sell Signal: When the Fast Moving Average crosses below the Slow Moving Average, it suggests downward momentum. The script places a visual marker on the chart above the candle.

2. Historical Signal Analysis Beyond just showing current signals, the script performs a comprehensive back-scan of historical data. It calculates:

  • The total number of "Up" and "Down" signals over a specific period.
  • A "Good Signal" percentage, which evaluates whether the price action following a crossover was successful (based on whether the subsequent candle closed in the expected direction).
  • This helps provide a statistical overview of how reliable the moving average crossovers have been on that specific asset.

3. Automated Alerts and Notifications The script is equipped with an active notification system. When a new crossover occurs in real-time:

  • It triggers a visual alert message on your screen.
  • It plays an audible sound file (e.g., "alert.wav").
  • The alerts are designed to tell the user to close opposite positions and enter a new trade at the current price.

User Interface & Safety Features

  • On-Screen Labels: The script automatically generates text labels on your chart. These display the name of the indicator, contact information, and specific trading status messages.
  • Expiration System: The tool includes a built-in "time lock." It checks the current date against a hardcoded deadline. If the current date passes the set limit, the indicator will display an expiration notice and stop performing its calculations until contacted by the author.
  • Customizable Parameters: Users can adjust the periods (how many bars are used to calculate averages), the type of moving average (Simple, Exponential, Smoothed, or Linear Weighted), and which price data (Close, Open, High, Low, etc.) should be used for the calculations.
