Probably a very basic question It was recommended to me that instead trying to get an edge by fooling around with the setting on my indicators that I simply use the standard setting. This was mostly because it is best to see what the crowd is looking at. But! as an example: Stock charts sets the bollinger band based on 20 periods trade ninja defaulted to 14 when I was looking at the es. I've seen different stochastic settings on different sites. So how do I know what the "standard" settings are? or if there really are any.
