Overview
The momentum oscillator calculates the change of price over a specified length of time as a ratio.

Interpretation Increasingly high values of the momentum oscillator may indicate that prices are trending strongly upwards. The momentum oscillator is closely related to MACD and Price Rate of Change (ROC).

Overview
The Chande Momentum Oscillator (CMO), developed by Tushar Chande, is an advanced momentum oscillator derived from linear regression. This indicator was published in his book titled "New Concepts in Technical Trading" in the mid 90's.

Interpretation
The CMO enters into overbought territory at +50, and oversold territory at -50. You can also create buy/sell triggers based on a moving average of the CMO. Also, increasingly high values of CMO may indicate that prices are trending strongly upwards. Conversely, increasingly low values of CMO may indicate that prices are trending strongly downwards.

Overview
The Volume Oscillator shows a spread of two different moving averages of volume over a specified period of time.

Interpretation
Offers a clear view of whether or not volume is increasing or decreasing.

Overview
Similar to the Volume Oscillator, the Price Oscillator is calculated based on a spread of two moving averages.

Interpretation
The Price Oscillator is basically a moving average spread. Buying usually occurs when the oscillator rises, and selling usually occurs when the oscillator falls.

Overview
Similar to the Price Oscillator except DPO is used when long-term trends or outliers make the underlying price difficult to analyze.

Interpretation
Buying occurs when the oscillator rises. Selling occurs when the oscillator falls.

Overview
Finds the nearest prime number from either the top or bottom of the series, and plots the difference between that prime number and the series itself.

Interpretation
This indicator can be used to spot market turning points. When the oscillator remains at the same high point for two consecutive periods in the positive range, consider selling. Conversely, when the oscillator remains at a low point for two consecutive periods in the negative range, consider buying.

Overview
The chaotic nature of stock market movements explains why it is sometimes difficult to distinguish daily charts from monthly charts if the time scale is not given. The patterns are similar regardless of the time resolution. Like the chambers of the nautilus, each level is like the one before it, but the size is different. To determine what is happening in the current level of resolution, the fractal chaos oscillator can be used to examine these patterns.

Interpretation
A buy signal is generated when the oscillator tops, and a sell signal is generated when the oscillator bottoms.

Overview
The rainbow oscillator is calculated based upon multiple time frames of a moving average.

Interpretation
The trend may reverse suddenly when values stay above 0.80 or below 0.20 for two consecutive days.

Overview
TRIX is a momentum oscillator that shows the rate of change of an exponentially averaged closing price.

Interpretation
The most common usage of the TRIX oscillator is to buy when the oscillator rises and sell when the oscillator falls.

Overview
The Vertical Horizontal Filter (VHF) identifies whether a market is in a trending or a choppy movement phase.

Interpretation
The VHF indicator is most commonly used as an indicator of market volatility. It is also frequently used as a component to other technical indicators.

Overview
The Ease of Movement oscillator displays a unique relationship between price change and volume.

Interpretation
The Ease of Movement oscillator rises when prices are trending upwards under low volume, and likewise, the Ease of Movement oscillator falls when prices are trending downwards under low volume.

Overview
The Welles Wilder's Directional Movement System contains five indicators; ADX, DI+, DI-, DX, and ADXR.

The ADX (Average Directional Movement Index) is an indicator of how much the market is trending, either up or down: the higher the ADX line, the more the market is trending and the more suitable it becomes for a trend-following system. This indicator consists of two lines: DI+ and DI-, the first one being a measure of uptrend and the second one a measure of downtrend.

Detailed information about this indicator and formulas can be found in Welles Wilder's book, "New Concepts in Technical Trading Systems". The standard Directional Movement System draws a 14 period DI+ and a 14 period DI- in the same chart panel. ADX is also sometimes shown in the same chart panel.

Interpretation
A buy signal is given when DI+ crosses over DI-, a sell signal is given when DI- crosses over DI+.

Overview
The True Range is a component of Wilder's Directional Movement System.

Overview
Developed by trader Larry Williams, the Williams' %R indicator measures overbought/oversold levels. This indicator is similar to the Stochastic Oscillator. The outputs range from 0 to -100.

Interpretation
The market is considered overbought when the %R is in a range of 0 to -20, and oversold when %R is in a range of -80 to -100.

Overview
Another indicator developed by trader Larry Williams, the Accumulation / Distribution indicator shows a relationship of price and volume.

Interpretation
When the indicator is rising, the security is said to be accumulating. Conversely, when the indicator is falling, the security is said to being distributing. Prices may reverse when the indicator converges with price.

Overview
The Chaikin Volatility Oscillator is a moving average derivative of the Accumulation / Distribution index. This indicator quantifies volatility as a widening of the range between the high and the low price.

Interpretation
The Chaikin Volatility Oscillator adjusts with respect to volatility, independent of long-term price action. The most popular interpretation is to sell when the indicator tops out, and to buy when the indicator bottoms out.

Overview
The Aroon indicator was developed by Tushar Chande in the mid 1990's. This indicator is often used to determine whether a stock is trending or not and how stable the trend is.

Interpretation
Trends are determined by extreme values (above 80) of both lines (Aroon up and Aroon down), whereas unstable prices are determined when both lines are low (less than 20).

Overview
The MACD is a moving average oscillator that shows potential overbought/oversold phases of market fluctuation. The MACD is a calculation of two moving averages of the underlying price/indicator.

Interpretation
Buy and sell interpretations may be derived from crossovers (calculated by the MACDSignal function), overbought / oversold levels of the MACD and divergences between MACD and underlying price.

Overview
This function returns the high price minus the low price for each bar.

Interpretation
This indicator is often used as a component for other technical indicators but can be used with a moving average to show the change in price action over time.

Overview
The Stochastic Oscillator is a popular indicator that shows where a security's price has closed in proportion to its closing price range over a specified period of time.

Interpretation
The Stochastic Oscillator has two components: %K (the SOPK function) and %D (the SOPD function). %K is most often displayed on a stock chart as a solid line and %D is often shown as a dotted line. The most widely used method for interpreting the Stochastic Oscillator is to buy when either component rises above 80 or sell when either component falls below 20. Another way to interpret the Stochastic Oscillator is to buy when %K rises above %D, and conversely, sell when %K falls below %D.
