Re: Parabolic Question

>From "Computer Analysis of the Futures Market,"

SAR[t] = SAR[t-1] + (AF * (EP[prior] - SAR[t-1]))

where:
   SAR[t] = current SAR
   SAR[t-1] = prior SAR
   EP = extreme price
   AF = acceleration factor, which normally starts at 0.02 and steps up in
   increments of 0.02 to a maximum of 0.20

and where the first SAR point is the extreme prior of the prior Parabolic
trade; thus SAR[1] = EP[prior].
