Is it possible to plot an indicator with two different colors in quantmod?
 one for positive numbers, and another for negative numbers?
Just like the style of addCMF()?

>library(quantmod)
>getSymbols('SBUX')
>barChart(SBUX)
>addTA(OpCl(SBUX), col=4, type='h', lwd=2)

The last line plot the indicator in one color only.

Thanks.

Michael
