A Simple Moving Average is an average price for a security over
a specified period of time. The chart tracks the change in the
average over time. You can select up to three time periods on
this chart, based on the intervals show in the chart. The
average smooths out the data to help investors more easily
identify trends. Traders tend to sell when a stock trades above
an average and buy when it falls below an average. Line 1 Period
Line 2 Period Line 3 Period An Exponential Moving Average is
similar to a simple moving average of a security’s prices over a
defined period of time, but it gives greater weight to more
recent data. You can select as many as three time periods. An
EMA chart allows investors to spot and respond more quickly to
recent trends that might take more time to appear in an SMA.
Standard Deviations Offset Bollinger Bands are used to compare
volatility and relative price levels over a period of time. The
chart shows two lines that define the upper and lower boundaries
of a stock’s normal price
