I don't believe there is an "established" indicator for this. However, this is something that could be coded very easily in any of the platforms available. But I'm with tommcginnis on this one. It will likely not show you anything you can "use" to be profitable long term. In my experience, moving averages and their derivatives are simply too slow to respond, because everyone else uses them. The big boys (and those in the know) know this, so you'll notice turnarounds right as the moving averages give a signal to enter/exit. Sure, you'll catch some big moves from time to time using them, but you'll give the profits right back and then some on the smaller moves due to these turnarounds. And that's if you haven't already done serious damage to your account, which limits your buying power. Been there, done that.
Well, essentially, the closest thing to what you're describing is a particularly-tuned MACD histogram. It's not an oscillator in terms of cycling between 0-100, but it is (ostensibly) centered around 0. (That 0-centeredness is false, by the way, right? Yep.) And in the meantime, you have to decide what "-10" means, or "+0.33" or whether "+12.2" in one market is comparable to "+2.4" in another market -- or in the same market on Wednesday as opposed to Tuesday. If you can't put the numerical output of your indicator into a single sentence, DON'T trade it.
