Getting Started
Here are a few examples of some of the more well-known indicators:
# "TTR Composite" (simulated data)
data(ttrc)
# Bollinger Bands
bbands <- BBands( ttrc[,c("High","Low","Close")] )
# Directional Movement Index
adx <- ADX(ttrc[,c("High","Low","Close")])
# Moving Averages
ema <- EMA(ttrc[,"Close"], n=20)
sma <- SMA(ttrc[,"Close"], n=20)
# MACD
macd <- MACD( ttrc[,"Close"] )
# RSI
rsi <- RSI(ttrc[,"Close"])
# Stochastics
stochOsc <- stoch(ttrc[,c("High","Low","Close")])
TTR works with the chartSeries() function in quantmod. Here’s an example that uses chartSeries() and adds TTR-calculated indicators and overlays to the chart.
# "TTR Composite" (simulated data)
data(ttrc)
# Use quantmod's OHLCV extractor function to help create an xts object
xttrc <- xts(OHLCV(ttrc), ttrc[["Date"]])
chartSeries(xttrc, subset = "2006-09/", theme = "white")
addBBands()
addRSI()
