Momentum Indicators

Momentum indicators measure the speed of movement.

Awesome Oscillator

The AwesomeOscillator function calculates the awesome oscillator based on low and high daily prices for a given stock. It is an indicator used to measure market momentum.

Median Price = ((Low + High) / 2)
AO = 5-Period SMA - 34-Period SMA.

result := indicator.AwesomeOscillator(low, high)

Chaikin Oscillator

The ChaikinOscillator function measures the momentum of the Accumulation/Distribution (A/D) using the Moving Average Convergence Divergence (MACD) formula. It takes the difference between fast and slow periods EMA of the A/D. Cross above the A/D line indicates bullish.

CO = Ema(fastPeriod, AD) - Ema(slowPeriod, AD)

co, ad := indicator.ChaikinOscillator(fastPeriod, slowPeriod, high, low, closing)

Most frequently used fast and short periods are 3 and 10. The DefaultChaikinOscillator function calculates Chaikin Oscillator with those periods.

Ichimoku Cloud

The IchimokuCloud, also known as Ichimoku Kinko Hyo, calculates a versatile indicator that defines support and resistence, identifies tred direction, gauges momentum, and provides trading signals.

Tenkan-sen (Conversion Line) = (9-Period High + 9-Period Low) / 2
Kijun-sen (Base Line) = (26-Period High + 26-Period Low) / 2
Senkou Span A (Leading Span A) = (Conversion Line + Base Line) / 2
Senkou Span B (Leading Span B) = (52-Period High + 52-Period Low) / 2
Chikou Span (Lagging Span) = Closing plotted 26 days in the past.

conversionLine, baseLine, leadingSpanA, leadingSpanB, laggingLine := indicator.IchimokuCloud(high, low, closing)

Percentage Price Oscillator (PPO)

The PercentagePriceOscillator function calculates a momentum oscillator for the price It is used to indicate the ups and downs based on the price. A breakout is confirmed when PPO is positive.

PPO = ((EMA(fastPeriod, prices) - EMA(slowPeriod, prices)) / EMA(longPeriod, prices)) * 100
Signal = EMA(9, PPO)
Histogram = PPO - Signal

ppo, signal, histogram := indicator.PercentagePriceOscillator(
    fastPeriod, 
    slowPeriod, 
    signalPeriod, 
    price
)

The DefaultPercentagePriceOscillator function calculates it with the default periods of 12, 26, 9.

ppo, signal, histogram := indicator.DefaultPercentagePriceOscillator(price)

Percentage Volume Oscillator (PVO)

The PercentageVolumeOscillator function calculates a momentum oscillator for the volume It is used to indicate the ups and downs based on the volume. A breakout is confirmed when PVO is positive.

PVO = ((EMA(fastPeriod, volumes) - EMA(slowPeriod, volumes)) / EMA(longPeriod, volumes)) * 100
Signal = EMA(9, PVO)
Histogram = PVO - Signal

pvo, signal, histogram := indicator.PercentageVolumeOscillator(
    fastPeriod, 
    slowPeriod, 
    signalPeriod, 
    volume
)

The DefaultPercentageVolumeOscillator function calculates it with the default periods of 12, 26, 9.

pvo, signal, histogram := indicator.DefaultPercentageVolumeOscillator(volume)

Relative Strength Index (RSI)

The Rsi function calculates a momentum indicator that measures the magnitude of recent price changes to evaluate overbought and oversold conditions.

RS = Average Gain / Average Loss
RSI = 100 - (100 / (1 + RS))

rs, rsi := indicator.Rsi(closing)

RSI 2

The Rsi2 function calculates a calculates a RSI with 2 period that provides a mean-reversion trading strategy. It is developed by Larry Connors.

rs, rsi := indicator.Rsi2(closing)

RSI Period

The RsiPeriod allows to calculate the RSI indicator with a non-standard period.

rs, rsi := indicator.RsiPeriod(period, closing)

Stochastic Oscillator

The StochasticOscillator function calculates a momentum indicator that shows the location of the closing relative to high-low range over a set number of periods.

K = (Closing - Lowest Low) / (Highest High - Lowest Low) * 100
D = 3-Period SMA of K

k, d := indicator.StochasticOscillator(high, low, closing)

Williams R

The WilliamsR function calculates the Williams R based on low, high, and closing prices. It is a type of momentum indicator that moves between 0 and -100 and measures overbought and oversold levels.

WR = (Highest High - Closing) / (Highest High - Lowest Low)

result := indicator.WilliamsR(low, high, closing)
