Once again, moving average crossovers work great when the trend is strong, but produce losses in the absence of a trend.

## What Is A Moving Average?

An exponential moving average has to start somewhere, so a simple moving average is used as the previous period’s EMA in the first calculation. Third, calculate the exponential moving average for each day between the initial EMA value and today, using the price, the multiplier, and the previous period’s EMA value. Exponential moving averages reduce the lag by applying more weight to recent prices. The weighting applied to the most recent price depends on the number of periods in the moving average. EMAs differ from simple moving averages in that a given day’s EMA calculation depends on the EMA calculations for all the days prior to that day.

### What is a monthly moving average?

A 12-month rolling average, or moving average, is simply a series of 12-month averages over multiple consecutive 12-month periods. This statistical tool can help you gauge the overall direction of a series of monthly data, because it smooths out the effects of month-to-month changes.
