Hi, Both following code examples plot Bollinger bands over the ticker main plot and William's Percent below the main plot.
1. chartSeries(YHOO,theme="white",TA = c(addBBands(200,2), addWPR(n=300))) 2. chartSeries(IB,theme="white",TA = c(addBBands(200,2))) addWPR(n=300) In general, if you like to plot indipendently a trading indicator computed by quantmod, you can do: wpr <- addWPR(n=300) plot(wpr@TA.values, type='l') -- or any other R plot library you like as in @TA.values are stored trading indicator values for any quantmod indicator.
