Fast Stochastics (FStoch)

Fast %K (FSTOCH) - The system identifies the highest high, lowest low, and the current Price for a specified Period.

It subtracts the lowest low from the current PRICE, and then divides the difference by the range, (where the range is the highest high - lowest low). The result becomes the first Fast %K value.

The system continues to calculate Fast %K values by excluding the oldest bar and including the next more recent bar before repeating the above calculation.

Fast %D (F STO %D) - Is a Moving Average of Fast %K values. The default for Fast %D is a Smoothed 3 Period Moving Average.

Users can choose between the Original and the Simple Algorithms. Generally, the simplified will be more responsive to price changes. The formulas for each are:

Original

K:= ((Close(@)- LoLevel(@,10))/ (HiLevel(@,10)- LoLevel(@,10)))*100;

D:= (MA( (Close(@)- LoLevel(@,10)),Smo,3)/ MA(( HiLevel(@,10)- LoLevel(@,10)),Smo,3))*100;

Simplified

K:= ((Close(@)- LoLevel(@,10))/ (HiLevel(@,10)- LoLevel(@,10)))*100;

D:= MA((Close(@)- LoLevel(@,10))/ ( HiLevel(@,10)- LoLevel(@,10)),Smo,3)*100;

Original Algorithm = [Moving Average (Closing Range)]/[Moving Average (Total Range)]

Simplified Algorithm = Moving Average [(Closing Range/Total Range)]

Closing Range = Close – Range Minimum

Total Range = Range Maximum – Range Minimum

Fast Stochastics Parameters

Parameter	Description
Display	Opens sub-window to set parameters • Color = Line color. • Weight = Line thickness. • MarkIt = Opens Specify Conditions window. • Display = Line style: line or histogram base 0 or base 50. • ShareScale = Determines whether sharing of the vertical scales between studies is accepted. Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. ShareScale must be On if study is overlaid on a study with multiple outputs.
Period	Number of bars in the lookback range.
Price	Price used to calculate study values.
HiLevel	Price used for the high level in the range.
LoLevel	Price used for the low level in the range.
Algorithm	Values: • Original = smoothing prior to dividing (close - range minimum/range) • Simplified = dividing prior to smoothing
Type	Moving average calculation. Values: • Simple • Smoothed • Exponential • Weighted • Centered • Median • Trix • Exponential Hull
OB/OS	Opens sub-window with overbought and oversold parameters: • Color = Select a color for the line. • Weight = Choose a thickness for the indicator. • Type = Choose fixed or dynamic. Fixed = uses Level as a fixed OB/OS value. Dynamic = uses Standard Deviation and Lookback for a dynamic OB/OS value:. OB: MA(@,Sim,lookback) + factor * STDDEV(@,lookback) OS: MA(@,Sim,lookback) - factor * STDDEV(@,lookback) where @ is the study • Std Dev = Multiplier used to calculate high and low. • Lookback = Number of bars to compare to the current bar. • Level = Percentage of average OB/OS used to calculate predictor Ob/OS levels. • Display = Click this check box to display the component. • Style = Choose a line style.
