Simple Moving Averages (20, 50, 200)

The Simple Moving Averages (20, 50, 200) indicator plots three essential trend-following lines on a single chart to help traders identify short, medium, and long-term market trends and potential reversal points.

Usage

The Usage section describes how the script can be used to interpret market momentum and trend direction. Traders typically use these specific moving average lengths to categorize market cycles:

• SMA 20 (Short-term): Used to gauge immediate momentum and short-term price fluctuations.
• SMA 50 (Medium-term): Serves as a standard benchmark for intermediate trend direction.
• SMA 200 (Long-term): Widely regarded by institutional traders to determine the overall primary trend of an asset.

Examples of Interpretation:

• Trend Confirmation: When the price is consistently above all three averages, the asset is considered to be in a strong bullish trend. Conversely, price action below these averages suggests a bearish trend.
• Crossover Signals: The indicator includes built-in logic for "Golden Crosses" and "Death Crosses." For example, when the 50-period SMA crosses above the 200-period SMA, it is often interpreted as a long-term bullish signal.
• Dynamic Support and Resistance: These averages often act as floors or ceilings where price may bounce or face rejection during a trend.

Details

The script calculates the simple moving average (SMA) by taking the sum of the closing prices over the specified periods (20, 50, and 200) and dividing that sum by the number of time periods.

The implementation features optimized alert conditions for crossover events. This includes alerts for the 20 SMA crossing the 50 SMA, and the 50 SMA crossing the 200 SMA. These alerts are set to trigger once per bar close to ensure signal validity. This tool was originally developed by @ayejay_ and has been refactored for performance and visual clarity.
