[ProfitTrailer:Feeder] Stochastics

Just like RSI the Stochastics Indicator is very often used in ProfitTrailer:Feeder and therefore I decides to create this script so people can easily test/tryout there specific inputs.

Note: Because there's a difference (in outcome) between the calculation function from TV and the traditional calculation (used by ProfitTrailer) I created an option to select the kind of calculation you prefer.

Enjoy!
