Hello, Xard,
probably this isn't at all helpful for someone like you but I just compared your Stochastics to a somewhat smoothed one
(Stochastic filtered + alert etc. on forex-station.com): color changes on slope
I know that you don't need the Stoch at all to trade your system but if you want it for confirmation, say, the smoothed version - though somewhat lagging - produces fewer false signals and by doing so may help beginners etc.
Anyway just an idea...
