**Technical Indicators** are the often squiggly lines found above, below and on-top-of the price information on a technical chart. Indicators that use the same scale as prices are typically plotted on top of the price bars and are therefore referred to as **“Overlays”**.

If you are new to stock charting and the use of technical indicators, the following article will help you get going:

**Introduction to Technical Indicators and Oscillators**– An in-depth introduction to the various kinds of technical indicators and oscillators out there. A “must read” article for StockCharts users.

Both Simple Moving Averages (SMAs) and Exponential Moving Averages (EMAs) are explained.**Moving Average Envelopes**A chart overlay consisting of a channel formed from simple moving averages.**Parabolic SAR**A chart overlay that shows reversal points below prices in an uptrend and above prices in a downtrend.**Pivot Points**A chart overlay that shows reversal points below prices in an uptrend and above prices in a downtrend.**Price Channels**A chart overlay that shows a channel made from the highest high and lowest low for a given period of time.**Volume By Price**A chart overlay with a horizontal histogram showing the amount of activity at various price levels.**Volume-Weighted Average Price (VWAP)**An intraday indicator based on total dollar value of all trades for the current day divided by the total trading volume for the current day.**ZigZag**A chart overlay that shows filtered price movements that are greater than a given percentage.

**Accumulation/Distribution Line**Combines price and volume to show how money may be flowing into or out of a stock.**Aroon**Uses Aroon Up and Aroon Down to determine whether a stock is trending or not.**Aroon Oscillator**Measures the difference between Aroon Up and Aroon Down.**Average Directional Index (ADX)**Shows whether a stock is trending or oscillating.**Average True Range (ATR)**Measures a stock's volatility.**BandWidth**Shows the percentage difference between the upper and lower Bollinger Band.**%B Indicator**Shows the relationship between price and standard deviation Bollinger Bands.**Chaikin Money Flow (CMF)**Combines price and volume to show how money may be flowing into or out of a stock Alternative to Accumulation/Distribution Line.**Chaikin Oscillator**Combines price and volume to show how money may be flowing into or out of a stock. Based on Accumulation/Distribution Line.**Chande Trend Meter (CTM)**Scores the strength of a stock's trend, based on several technical indicators over six different timeframes.**Commodity Channel Index (CCI)**Shows a stock's variation from its “typical” price.**Coppock Curve**An oscillator that uses rate-of-change and a weighted moving average to measure momentum.**Correlation Coefficient**Shows the degree of correlation between two securities over a given timeframe.**DecisionPoint Price Momentum Oscillator (PMO)**An advanced momentum indicator that tracks a stock's rate of change.**Detrended Price Oscillator (DPO)**A price oscillator that uses a displaced moving average to identify cycles.**Ease of Movement (EMV)**An indicator that compares volume and price to identify significant moves.**Force Index**A simple price-and-volume oscillator.**Mass Index**An indicator that identifies reversals when the price range widens.**MACD (Moving Average Convergence/Divergence Oscillator)**A momentum oscillator based on the difference between two EMAs.**MACD Histogram**A momentum oscillator that shows the difference between MACD and its signal line.**Money Flow Index (MFI)**A volume-weighted version of RSI that shows shifts is buying and selling pressure.**Negative Volume Index (NVI)**A cumulative volume-based indicator used to identify trend reversals.**On Balance Volume (OBV)**Combines price and volume in a very simple way to show how money may be flowing into or out of a stock.**Percentage Price Oscillator (PPO)**A percentage-based version of the MACD indicator.**Percentage Volume Oscillator (PVO)**The PPO indicator applied to volume instead of price.**Price Relative / Relative Strength**Technical indicator that compares the performance of two stocks to each other by dividing their price data.**Pring's Know Sure Thing (KST)**A momentum oscillator from Martin Pring based on the smoothed rate-of-change for four different timeframes.**Pring's Special K**A momentum indicator from Martin Pring that combines short-term, intermediate and long-term velocity.**Rate of Change (ROC) and Momentum**Shows the speed at which a stock's price is changing.**Relative Strength Index (RSI)**Shows how strongly a stock is moving in its current direction.**RRG Relative Strength**Uses RS-Ratio to measure relative performance and RS-Momentum to measure the momentum of relative performance.**StockCharts Technical Rank (SCTR)**Our relative ranking system based on a stock's technical strength.**Slope**Measures the rise-over-run for a linear regression.**Standard Deviation (Volatility)**A statistical measure of a stock's volatility.**Stochastic Oscillator (Fast, Slow, and Full)**Shows how a stock's price is doing relative to past movements. Fast, Slow and Full Stochastics are explained.**StochRSI**Combines Stochastics with the RSI indicator to help you see RSI changes more clearly.**TRIX**A triple-smoothed moving average of price movements.**True Strength Index**An indicator that measures trend direction and identifies overbought/oversold levels.**Ulcer Index**An indicator designed to measure market risk or volatility.**Ultimate Oscillator**Combines long-term, mid-term and short-term moving averages into one number.**Vortex Indicator**An indicator designed to identify the start of a new trend and define the current trend.**Williams %R**Uses Stochastics to determine overbought and oversold levels.
