Plot highest of last two high pivots

Since you are requesting a solution for a chart study I moved your question out of the Frequently Asked Questions topic and into the Chart Studies topic.

I'm not sure this solution is going to do what you expect. But I believe that it does continue to track the highest of the last two swing high pivots. The only thing lacking is some sort of a rule which would allow this to reset the plot to a lower value as prices trend lower.

I only get 15 minutes for each free solution I provide in this forum. And this is the most detailed solution I can provide within that time limit.

input Left = 3; # Number of bars to the left of the pivot
input Right = 3; # Number of bars to the right of the pivot
def isPivotHigh = high > Highest(high[1], Left) and high >= Highest(high[-Right], Right);
def pivotHigh = if isPivotHigh then high else Double.NaN;
rec lastPivotHigh1 = if !IsNaN(pivotHigh) then pivotHigh else lastPivotHigh1[1];
rec lastPivotHigh2 = if !IsNaN(pivotHigh) and !IsNaN(lastPivotHigh1[1]) and pivotHigh != lastPivotHigh1[1] then lastPivotHigh1[1] else lastPivotHigh2[1];
plot PivotHigh1 = lastPivotHigh1;
PivotHigh1.SetDefaultColor(Color.RED);
PivotHigh1.SetPaintingStrategy(PaintingStrategy.POINTS);
rec extendHighestPivot = if lastPivotHigh1 <> lastPivotHigh1[1] then Max(lastPivotHigh1, Max(lastPivotHigh1[1], extendHighestPivot[1])) else extendHighestPivot[1];
plot highestOfTwoPivots = extendHighestPivot;
highestOfTwoPivots.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
highestOfTwoPivots.SetDefaultColor(Color.MAGENTA);
