Fast And Slow Kurtosis

Fast And Slow Kurtosis (FSK) was authored by U. Jenson for Omega Research. The FSK uses Momentum, previous Momentum and previous FSK (feedback) along with a percentage factor to plot its value. A signal line, which is an weighted moving average of itself, is also given. The user may change the input (close), method (WMA) and period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.

How To Trade Using Fast And Slow Kurtosis

If the FSK crosses below the signal line a sell signal will be generated. Conversely, if the FSK crosses above the signal line a buy signal will be given.

Plot2: sig = ma(method, index, period, fsk);
highSell = fsk for last sell signal, reset to max_negative at each  buy signal;
lowBuy = fsk for last buy signal, reset to max_positive at each sell signal;
buy = crossedAbove(FSK, SIG);
sell = crossedBelow(FSK, SIG);
