One thing you can do to optimize it is to precompute the higuer highs and lower lows and then in the main loop simply use this code:
for (int iBar = iFirstBar; iBar < Bars; ++iBar)
{
double Hi1 = HH[iBar];
double Lo1 = LL[iBar];
double Hi2 = HH[iBar - PeriodFRAMA];
double Lo2 = LL[iBar - PeriodFRAMA];
double Hi3 = Math.Max(Hi1, Hi2);
double Lo3 = Math.Min(Lo1, Lo2);
double N1 = (Hi1 - Lo1) / PeriodFRAMA;
double N2 = (Hi2 - Lo2) / PeriodFRAMA;
double N3 = (Hi3 - Lo3) / PeriodFRAMA2;
double D = (Math.Log(N1 + N2) - Math.Log(N3)) / log2;
double ALFA = Math.Exp(-4.6 * (D - 1.0));
ExtMapBuffer1[iBar] = ALFA * adBasePrice[iBar] + (1 - ALFA) * ExtMapBuffer1[iBar - 1];
}
for (int iBar = iFirstBar; iBar < Bars; ++iBar)
{
double Hi1 = HH[iBar];
double Lo1 = LL[iBar];
double Hi2 = HH[iBar - PeriodFRAMA];
double Lo2 = LL[iBar - PeriodFRAMA];
double Hi3 = Math.Max(Hi1, Hi2);
double Lo3 = Math.Min(Lo1, Lo2);
double N1 = (Hi1 - Lo1) / PeriodFRAMA;
double N2 = (Hi2 - Lo2) / PeriodFRAMA;
double N3 = (Hi3 - Lo3) / PeriodFRAMA2;
double D = (Math.Log(N1 + N2) - Math.Log(N3)) / log2;
double ALFA = Math.Exp(-4.6 * (D - 1.0));
ExtMapBuffer1[iBar] = ALFA * adBasePrice[iBar] + (1 - ALFA) * ExtMapBuffer1[iBar - 1];
