Technical analysts are never content to rest on those metric algorithms that have been established when each one thinks a better system can be devised. The derivative oscillator was created by and published by Constance Brown in her book, Technical Analysis for the Trading Professional. Essentially, the derivative oscillator takes two pre-existing metrics: the moving average convergence-divergence (MACD) chart and the Relative Strength Index (RSI) in combination to create a graph that can better signal for buy and sell signs going into relative strength or weakness trends.
Of course, all technical analysis always looks better in retrospect. Using it to predict the future is still more art than science for many.

fifty six bucks a share and your total value is now fifty eight bucks. well you
could turn around today and sell the bundle that moment, and you'll have
turned your dollar into two dollars of profit really fast. and obviously had the [equation on screen]
stock not skyrocketed so quickly well you would have lost everything. still you
lucked out and now you're sitting on some serious cash, courtesy of your call [two men in a tub of cash]
