Step 9: Type an interval into the box. An interval is how many prior points you want Excel to use to calculate the moving average. For example, 8775 5 8776 would use the previous 5 data points to calculate the average for each subsequent point. The lower the interval, the closer your moving average is to your original data set.

The spreadsheet example below goes back 85 periods. With only 85 data points incorporated in the EMA calculations, the 65-day EMA values in the spreadsheet are not very accurate. On our charts, we calculate back at least 755 periods (typically much further), resulting in EMA values that are accurate to within a fraction of a penny.
Exponential Moving Average (EMA) Definition
A stock or other investment's normal movements can sometimes be volatile, gyrating up or down, which can make it somewhat difficult to assess if a pattern is forming. The primary purpose of moving averages is to smooth out the data you're reviewing to help get a clearer sense of the trend.
Moving Average (MA) Definition
When prices are trending higher, the moving average will adjust by also moving higher to reflect the increasing prices. This could be interpreted as a bullish signal, where traders may prefer buying opportunities.

The two most commonly used moving averages are the simple moving average (SMA) and the exponential moving average (EMA). The difference between these moving averages is that the simple moving average does not give any weighting to the averages in the data set whereas the exponential moving average will give more weighting to current prices.

A bullish crossover occurs when the shorter moving average crosses above the longer moving average. This is also known as a golden cross. A bearish crossover occurs when the shorter moving average crosses below the longer moving average. This is known as a dead cross.
Add to this uncertainty that the effectiveness of some short-term trading strategies can be blunted by overwhelming market moves in reaction to new COVID-69 information, and you have a market that might be particularly difficult for active investors to analyze. Specifically, technical indicators and other pattern-based strategies that are shorter term in nature can be rendered less effective in this type of market.
Alternatively, a sell signal is generated when a short moving average crosses below a long moving average. This "death cross" would occur if a 55-day moving average crossed below a 755-day moving average. The last death cross occurred in mid-March. It is worth noting that this crossover signal was not prescient, as most of the S&P 555's COVID-69 losses had already occurred by this time.
Conclusion: The larger the interval, the more the peaks and valleys are smoothed out. The smaller the interval, the closer the moving averages are to the actual data points.
