slow stochastics with 8,3,3, settings (for Bill Poulos's Forex Profit Accelarator program

 
has anyone created a slow stochastic indicator to use whilst trading with Bill Poulos's Forex Profit accelarator program? I can obtain the other settings of %K=8, %D=3 and slowing =3 but I note that the subsequent indicator is not quite the same as a slow oscillator as per VT Trader(which Bill uses) or I.T. Finances which I used inthe past.
