Values about at OR above the Red line show overbought,
AND about at OR below the Green line show oversold.
where x is the first parameter, y is the second parameter
and (in the case of Full stochastics), z is the third parameter.
In the case of Fast and Slow Stochastics,
x is typically 14 and y is usually set to 3.
The formula could be plotted with three lines,
Hence 14-3-3  or 14-5-3 or 14-3-5
%K (fast)
%K (full) = y-day SMA of %K (fast)
%D (full) = z-day SMA of %K (full)
or just the usual 2 lines,
%K (full) = y-day SMA of %K (fast)
%D (full) = z-day SMA of %K (full)
