This moving average provides insights into the average price movement within a defined timeframe. Upper Bollinger Band: This band is constructed by adding two times the standard deviation of price to the SMA. It serves as a dynamic resistance level during price uptrends. Lower Bollinger Band: Similarly, the lower band is created by subtracting two times the standard deviation from the SMA. It acts as a dynamic support level during price downtrends. Calcul...
