Third, calculate the exponential moving average for each day between the initial EMA value and today, using the price, the multiplier, and the previous Exponential Moving Average (EMA) Honestly, EMA’s provide little difference from their cousin, the SMA.

The EMA starts with the SMA data but adds a multiplier to the more recent price data points than the past ones. The primary difference between an EMA and an SMA is the sensitivity each one shows to changes in the data used in its calculation. SMA calculates the average of price data, while EMA gives more

Bollinger suggests increasing the standard deviation multiplier to 2.1 for a 50-period SMA and decreasing the standard deviation multiplier to 1.9 for a 10-period SMA. Bollinger Bands reflect direction with the 20-period SMA and volatility with the upper/lower bands. As such, they can be used to determine if prices are relatively high or low.
