I believe that the code below is what you are looking for. Looking at a chart you should see identical plots over top of each other. My apologies to any with color blindness.

//Resline.afl
//
>H;
TwoHigh = Ref(H,-1);
ThreeHigh = Ref(H,-2);
ResLine = ValueWhen( ThreeHigh < TwoHigh AND TwoHigh > OneHigh,TwoHigh,1);
Plot(ResLine,"ResLineArray", colorBlue, styleLine | styleLine);
ResLine = NULL;
for (i = 2; i < BarCount; i++) {
if (ThreeHigh[i] < TwoHigh[i] && TwoHigh[i] > OneHigh[i]) {
ResLine[i] = TwoHigh[i];
} else {
ResLine[i] = ResLine[i - 1];
}
}
Plot(ResLine,"ResLineLoop",colorYellow, styleDashed, null, null, null, 1);
