A technical indicator is a mathematical calculation based on historical price, volume, or open interest information that aims to forecast financial market direction.

Stock Chart supports 10 types of technical indicators: Accumulation Distribution, ATR, EMA, SMA, TMA, Momentum, MACD, RSI, Stochastic, and Bollinger Band. Use the indicator dropdown to add or remove the required indicator types.

Accumulation Distribution

Accumulation Distribution combines price and volume to show potential money flow into or out of a stock. To render an Accumulation Distribution indicator, set the indicator Type to AccumulationDistribution. To calculate the signal line, the Volume field must be included in the DataSource.

Average True Range (ATR)

ATR measures stock volatility by comparing the current value with the previous value. To render an Average True Range (ATR) indicator, set the indicator Type to Atr.

Exponential Moving Average (EMA)

Moving average indicators are used to define the direction of the trend. To render an EMA indicator, set the indicator Type to Ema.

Momentum

Momentum shows the speed at which the stock price is changing. To render a Momentum indicator, set the indicator Type to Momentum. The Momentum indicator is represented by two lines (upperLine, signalLine). In the Momentum indicator, the upperBand value is always rendered at 100.

Moving Average Convergence Divergence (MACD)

MACD is based on the difference between two EMAs. To render a MACD indicator, set the indicator Type to Macd. The MACD indicator is represented by the MACD line, signal line, and MACD histogram. The histogram highlights the difference between the MACD line and the signal line.

Relative Strength Index (RSI)

RSI shows how strongly a stock is moving in its current direction. To render an RSI indicator, set the indicator Type to Rsi. The RSI indicator is represented by three lines (upperBand, lowerBand, signalLine). The upperBand and lowerBand values are customized by the OverBought and OverSold properties, and the signalLine is calculated using the RSI formula.

Simple Moving Average (SMA)

Moving average indicators are used to define the direction of the trend. To render an SMA indicator, set the indicator Type to Sma.

Stochastic

Stochastic indicates how a stock compares to its previous state. To render a Stochastic indicator, set the indicator Type to Stochastic. The Stochastic indicator is represented by four lines (upperLine, lowerLine, periodLine, signalLine). The upperBand and lowerBand values are customized by the OverBought and OverSold properties, and the periodLine and signalLine are rendered based on the stochastic formula.

Triangular Moving Average (TMA)

Moving average indicators are used to define the direction of the trend. To render a TMA indicator, set the indicator Type to Tma.

Bollinger Band

A Stock Chart overlay that shows the upper and lower limits of normal price movements based on the standard deviation of prices. To render a Bollinger Band, set the indicator Type to BollingerBand. The Bollinger Band is represented by three lines (upperLine, lowerLine, signalLine), and the default StandardDeviations value is 2.
