Indicators

Indicators is a Julia package offering efficient implementations of many technical analysis indicators and algorithms. This work is inspired by the TTR package in R and the Python implementation of TA-Lib, and the ultimate goal is to implement all of the functionality of these offerings (and more) in Julia. This package has been written to be able to interface with both native Julia Array types, as well as the TS time series type from the Temporal package. Contributions are of course always welcome for wrapping any of these functions in methods for other types and/or packages out there, as are suggestions for other indicators to add to the lists below.

Implemented

Moving Averages

  • SMA (simple moving average)
  • WMA (weighted moving average)
  • EMA (exponential moving average)
  • TRIMA (triangular moving average)
  • KAMA (Kaufman adaptive moving average)
  • MAMA (MESA adaptive moving average, developed by John Ehlers)
  • HMA (Hull moving average)
  • ALMA (Arnaud-Legoux moving average)
  • SWMA (sine-weighted moving average)
  • DEMA (double exponential moving average)
  • TEMA (triple exponential moving average)
  • ZLEMA (zero-lag exponential moving average)
  • MMA (modified moving average)
  • MLR (moving linear regression)
    • Prediction
    • Slope
    • Intercept
    • Standard error
    • Upper & lower bound
    • R-squared

Momentum Indicators

  • Momentum (n-day price change)
  • ROC (rate of change)
  • MACD (moving average convergence-divergence)
  • RSI (relative strength index)
  • ADX (average directional index)
  • Parabolic SAR (stop and reverse)
  • Fast & slow stochastics
  • SMI (stochastic momentum indicator)
  • KST (Know Sure Thing)
  • Williams %R
  • CCI (commodity channel index)
  • Donchian channel
  • Aroon indicator + oscillator

Volatility Indicators

  • Bollinger Bands
  • Average True Range

    • Fast Stochastics
    • Stochastic Momentum Index
  • MMA (modified moving average)
  • ZLEMA (zero lag exponential moving average)
  • Hamming moving average
  • VWMA (volume-weighted moving average)
  • VWAP (volume-weighted average price)
  • EVWMA (elastic, volume-weighted moving average)
  • VMA (variable-length moving average)
