FastStoch & FullStoch
FastStoch and FullStoch in Amibroker AFL are stochastic oscillators used to measure momentum. FastStoch reacts quickly to price changes, while FullStoch is smoother as it considers a more extended period. Traders use these indicators to identify overbought or oversold conditions in the market. When coupled with other analysis tools, they offer insights into potential trend shifts or continuation points.

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)
