just want to highlight, For Stochastics implementation on most trading platforms, besides apply moving on K to get a smooth K (aka Slow K) there is an option for internal smoothing of %K. Ths works by take a moving average of the differences (i.e. C-LowestL and HighestH-LowestL) before computing %K. TTR stoch function, smoothing is applied on final K values to obtain slow K (or fast D) and slow D. Implicitly, this means internal smoothing period = 1. not too sure if there will be an update to include the internal smoothing option for internal smoothing period > 1.
I wasn't planning on providing an update, but I will now that you've brought it to my attention. :-) How would you suggest it be implemented? Should I do more than add a slowK=1 argument and add slowK output? Just to make sure I understand, slowK and fastD should be equal when the slowK periods = 1, correct?
this might answer some doubts on why stochastics on TTR may differ from some trading platforms where the default internal smoothing period is 3. rgds Stanley ? ? ? ?[[alternative HTML version deleted]]
