hi xgcsmith
Well the settings come down to what sort of time frame you wish to use, how you wish to use the stochastic (ie crossover, divergence etc) and the no of trades you are trying to generate.
There are no general settings as such, but 14,3,3 tends to be a bog standard setting that online historical charts may adopt.
A word of warning though.......I'd advise you to incorporate price action into your strategy and not relay on the stochastic alone to signal entry as you'll end up getting whipped about.
In addition, don't try and optimise the settings. You're better off sticking to one or two settings and learning it's quirks with price action.
Having said that, for me it's the only indicator I've found to be of any use!
Cheers
