The method of applying a moving average to a chart is the way you use it to analyze the price action. There are three main methods: crossover, trend-following, and mean-reversion. Crossover method involves using two moving averages with different periods and looking for the points where they cross each other. When a faster moving average crosses above a slower one, it indicates a bullish signal. When it crosses below, it indicates a bearish signal. Trend-following method involves using a single moving average and looking for the direction and slope of it. When the price is above the moving average and the moving average is rising, it indicates an uptrend. When the price is below the moving average and the moving average is falling, it indicates a downtrend. Mean-reversion method involves using a single moving average and looking for the deviations of the price from it. When the price is far above the moving average, it indicates an overbought condition. When the price is far below the moving average, it indicates an oversold condition.
