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 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 range as determined by recent volatility, measured by standard deviation, and a moving average of the security’s price. Bollinger bands are often used to identify a period of low volatility and to prepare for a move above or below a trading range.
Moving Average Convergence-Divergence charts show how two moving averages move together and apart over time. They are used in similar fashion to other momentum indicators to help identify overbought and oversold conditions. The MACD is calculated by taking the difference of the two averages and plotting it as a line, known as the MACD line. A moving average of that difference is also plotted to serve as a buy/sell signal and is called the signal line. In a rally, rally will cause the difference between the two lines will increase until some extreme value is reached, signaling an overbought condition. Conversely, in a down market, the difference will become large but in the negative direction until an extreme is reached, signaling an oversold condition.
The relative-strength index (RSI) is a widely used momentum indicator that measures the price of a security against past performance. Typically, stock traders use a 14-day RSI, which focuses on how fast prices have been moving over a 14-day period. The RSI value ranges from 0 to 100; values above 75 indicate a possible overbought situation and values below 25 indicates a possible oversold condition. Many traders use it to determine if a stock is overbought or oversold.
ROC (Rate of Change) shows the difference between the closing price of that day and the close N days ago.
