The Moving Average is one
of the classical and most reliable tool for technical analysis.A Moving
Average is an indicator that shows the average value of a security's
price over a period of time. When calculating a moving average, a
mathematical analysis of the security's average value over a
predetermined time period is made. As the security's price changes, its
average price moves up or down. Moving averages can be calculated on any
data series including a security's open, high, low, close, volume, or
another indicator. The critical element in a moving average is the
number of time periods used in calculating the average. The key is to
find a moving average that will be consistently profitable.
There are two popular types of moving averages:
- Simple Moving Average (SMA)
- Exponential Moving Average (EMA)
The only significant difference between the EMA and SMA is the weight assigned to the most recent data.
- Simple moving averages apply equal weight to the prices.
- Exponential moving averages apply more weight to recent prices.
