Fast Stochastic

Fast Stochastic

The Fast Stochastic is a kind of George C. Lane’s stochastic oscillator.

The Fast Stochastic is the indicator that shows ratio between the current close price and the maximum/minimum of the preset period of time. This means the indicator is calculated on the moving data window and shows the price change rate.

The Fast Stochastic is shown in a chart as two lines %K and %D.

Classical formula to compute the Fast Stochastic is the following:

%K(i) = 100*(Close(i) – MaxHigh(N)) / (MaxHigh(N) – MinLow(N));

%D(i) = MA(%K(i), P);

Close(i) – close price of the current bar;
MaxHigh(N) – maximum High for N preceding periods;
MinLow(N) – minimum Low for N preceding periods;
MA – moving average;
N – the range of High/Low computation;
P – smoothing period for %D(i).
