**QCharts - Technical Studies Overview And Definitions**

**The AutoWave is a study that detects Fibonacci-ratio patterns in price swings. It can report existing patterns and patterns that would exist, if prices move to a new level. It can also show the swings themselves as a series of line segments.**

__AutoWave__

**The Accumulation/Distribution is a momentum indicator that associates changes in price and volume. The indicator is based on the premise that the more volume that accompanies a price move, the more significant the price move.**

__Accumulation/Distribution__

__Average True Range__The Average True Range ("ATR") is a measure of volatility.

__Bollinger Bands__The Bollinger Bands indicate previous market volatility by taking the standard deviation of the last period's closing prices and adding or subtracting a multiple (band width - usually 2) of that value to a simple moving average of the same number of closes.

The result is an upper band marking two standard deviations above the average and a lower band two standard deviations below the average. When the market has been volatile during the period, the bands get wider. The bands become narrower when the market has been less volatile.

Choppiness IndexChoppiness Index

The Choppiness Index measures the ratio of the average price range over a length of intervals to the price range over the entire length. A lower ratio indicates directionality or trendiness of a market, and a higher ratio indicates choppiness or lack of directionality.

**The Commodity Channel Index ("CCI") measures the variation of a security's price from its statistical means.**

__Commodity Channel Index__

__Directional Movement (ADX)__In Directional Movement, the +DI line (default blue) shows the average percentage of the range that is upward movement; -DI (default red) shows the percentage that is downward movement. The crossing of these lines indicates a change in trend. The ADXR line indicates how much the instrument is trending - below 20 indicates a non-trending environment.

__Donchian Channels__The Donchian Channels plot the highest high and lowest low over the last period. It indicates volatility and support/resistance levels. Offset shifts the channels left and right.

__Envelopes__*The Envelopes are calculated and plotted based on a fixed percentage above and below a moving average regardless of the volatility.*

__Float Turnover Channel__The Float Turnover Channel shows the number of bars required to trade a stock’s "float," or available shares.

__Keltner Channel__

The Keltner Channel is a moving average band indicator whose upper and lower bands adapt to changes in volatility by using the average true range. The Keltner Channel is used to signal price breakouts, show trend, and give overbought and oversold readings.

__MACD and the MACD Histogram__The MACD plots the difference between two exponential moving averages (MACD), and an average of that difference over time (Signal). The MACD Histogram plots the difference between the MACD and Signal lines.

**A Moving Average is an indicator that shows the average value of a security's price over a period of time. When calculating a moving average, a mathematical analysis of the security's average value over a predetermined time period is made. As the security's price changes, its average price moves up or down.**

__Moving Average__

__What is a Simple Moving Average?__

**A Simple Moving Average plots the average price of the last period's closing prices. If the period is set to 10 and the chart time interval is set to Daily, then the moving average is the average of the last 10 daily closing prices. If the current price is above the moving average, the stock is trending up in that time frame. Offset shifts the plot of the moving average left (negative offset) and right (positive offset) by the offset number of price intervals**

__What is an Exponential Moving Average?__

An Exponential Moving Average plots an average of the price series using exponential smoothing. Instead of taking the average price of the last period time intervals, this method takes a weighted average of the most recent price and the average price from yesterday. The weighting factor is determined from the period.

__Momentum__The Momentum indicator measures the amount that a security's price has changed over a given time span.

**The Money Flow Index ("MFI") is a momentum indicator that measures the strength of money flowing in and out of a security.**

__Money Flow Index__

__On Balance Volume__*On Balance Volume plots a running sum of volume in each interval. If an interval closes up from the previous interval, the volume during that interval is added to the running sum. If the close of an interval is down from the previous interval, the volume is subtracted from the running sum.*

__Open Interest__Open Interest is a calculation that is used primarily with options and futures contracts. Open Interest refers to the number of contracts remaining open at the end of the days trading.

**The Parabolic Time/Price System, developed by Welles Wilder, is used to set trailing price stops and is usually referred to as the "SAR" (stop-and-reversal).**

__Parabolic SAR__

**The Percentage Price Oscillator is a technical momentum indicator showing the relationship between two moving averages.**

__Percent Price Oscillator__

__Pivots__The Pivots are studies that display price levels based on recent time intervals. __Daily Pivot__The daily pivot considers yesterday’s open, close and price range when computing price pivot levels for today.

__Weekly Pivot__

The weekly pivot uses last week’s trading range to compute values for this week.

__Relative Strength Index (RSI)__Created by Welles Wilder, the RSI is an indicator of the strength of the direction of price closes over the period number of price intervals. It does so by taking a ratio of the closes in the up direction to the closes in the down direction

**The Price Rate-of-Change ("ROC") indicator displays the difference between the current price and the price x-time periods ago. The Momentum indicator displays the same information, but expresses it as a ratio.**

__Rate of Change (ROC)__**The Stochastic plots %K, the location of the current price relative to the highest high and lowest low over the last period, where the highest high over the last period is 100% and the lowest low is 0%. The primary %K line (default blue) is used to calculate a %D line, which is a moving average of %K over %D Smoothing length. You can affect a Slow Stochastic by first smoothing the %K line with a %K Smoothing value greater than one.**

__Stochastic__

__Slow Stochastic__

The function of the Slow Stochastic oscillator is to add additional smoothing to the Stochastic oscillator thereby improving signal accuracy and more defined interpretation.

__Stochastic RSI__The Stochastic RSI plots the Stochastic %D values of the Relative Strength Index.

**Volume is simply the number of shares (or contracts) traded during a specified time frame (e.g., hour, day, week, month, etc).**

__Volume__

**Volume At Price (VAP) creates a histogram of the prices at which trades occurred.**

__Volume at Price__

**The Williams %R (pronounced "percent R") is a momentum indicator that measures overbought/oversold levels.**
