Bollinger Bands
Bollinger Bands are volatility bands placed above and below a moving average. Volatility is based on the standard deviation, which changes as volatility increases and decreases. The bands automatically widen when volatility increases and narrow when volatility decreases. (Note: Bollinger Bands™ is a registered trademark of John Bollinger)
Moving Average
Moving averages smooth the price data to form a trend following indicator. They do not predict price direction, but rather define the current direction with a lag. Moving averages lag because they are based on past prices.
Exponential Moving Average
Moving averages smooth the price data to form a trend following indicator. They do not predict price direction, but rather define the current direction with a lag. Moving averages lag because they are based on past prices. Exponential moving averages reduce the lag by applying more weight to recent prices.
MACD
The Moving Average Convergence Divergence (MACD) is a trend-following momentum indicator showing the relationship between two moving averages of prices. It shows positive momentum when it is above the zero line, and negative momentum when it is below the zero line.
Relative Strength Index
A technical momentum indicator that compares the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions of an asset. Uses an exponential moving average for the computation.
Momentum
The rate of acceleration of a security's price or volume. The idea of momentum in securities is that their price is more likely to keep moving in the same direction than to change directions.
