Simple Moving Average Formula To calculate a 5 day simple moving average ("SMA"), take the sum of the last 5 days prices and divide by 5. 从上面的表格我们可以看到,在第9天,简单移动平均结果是17.2,与第8天的简单移动平均15.8相比有一个较大的跳跃,而第8、9两天的实际数据为17、17并没有变化。
Exponential moving average slope is also easier to determine: the slope is always down when price closes below the moving average and always up when price is above.Exponential Moving Average FormulaTo calculate an exponential moving average (EMA):...

FormulaThe classic EMA formula is: <math> \operatorname{EMA}(price, N)_i = \alpha \times price_{i} + (1 - \alpha) \times \operatorname{EMA}(price, N)_{i-1} </math> where <math> \alpha = \dfrac {2} {N + 1} </math> Unlike Simple Moving Average, where the weight...
When generating the SMA, traders must first calculate this average by adding prices over a given period and dividing the total by the total number of periods. The information is then plotted on a graph. The formula for Simple Moving Average is written as follows: ...

Calculating the Exponential Moving Average The formula for calculating the EMA is as follows: As exemplified in the chart above, EMAs calculated over a fewer number of periods (i.e., based on more recent prices) show a higher weightage than those calculated over longer periods. It ...
Common parameters include eight or more moving averages and intervals that range from a two-day moving average to a 200- or 400-day moving average. For ease of analysis, keep the type of moving average consistent across the ribbon—for example, use only exponential moving averag...
An exponential moving average (EMA) is a type ofmoving average (MA)that places a greater weight and significance on the most recent data points.1The exponential moving average is also referred to as the exponentiallyweightedmoving average. An exponentially weighted moving average reacts more signifi...
