SMA = Simple Moving Average (A simple, or arithmetic, moving average that is calculated by adding the closing price of the security for a number of time periods and then dividing this total by the number of time periods. Short-term averages respond quickly to changes in the price of the underlying, while long-term averages are slow to react.)

EMA = Exponential Moving Average (A type of moving average that is similar to a simple moving average, except that more weight is given to the latest data. Also known as "exponentially weighted moving average")

The number in parentheses represents the number of moving average lines that will be drawn….

• SMA represents single line using the period specified in the entry box next to the "Moving Averages" dropdown.
• SMA (2) represents 2 lines. The 2nd line will multiply the period by a factor of 2.
• SMA (3) represents 3 lines. The 2nd line will be the same as for SMA (2). The 3rd line will multiply the period by a factor of 3.

For example, if a period of 9 is indicated in the entry box, SMA (3) will show 3 lines; the 1st will be 9 periods, the 2nd will be 18 periods, the 3rd line will be 27 periods. EMA works similarly to the SMA illustrated above.

What constitutes a "Period"? When looking at charting that is greater than 10 days, then the "period" is in days. However, when looking at interval data (1day, 5day, 10day charts), then the period is in intervals. At this time, our system provides intervals in minutes for the 1d, 5d, and 10d charts.
