Sacha,
Me again. That 'drop-n-drag' thingie really does work. Much thanks for pointing out how to do it.
Just now, I plotted an oscillator (which generally plots as a single, wiggly line) and dragged a moving average onto it. NOW, da, dah, I've got an oscillator that generates crisp, Buy/Sell signals rather than just eye-ball guesses. So cool.
