another indicator chasing the holy grail?

wasn't going to spend another dime on so-called revolutionary tools, but couldn't resist the free demo of this VWAP Stdev Bands indicator the other night. yeah, i know, it's like believing in unicorns at this point. it's basically VWAP with a sprinkle of standard deviation to pretend it'll outsmart the market. to its credit, i did see it align with some support/resistance levels, but haven't we heard this story before? so far it's not the messiah of indicators, but then again, what is? if anyone's expecting a miracle for their $29, best to look elsewhere. thoughts?
