Calculation

//period = user defined, default = 25
//MOE = more or equal, LOE = less or equal
//index = current bar number

high_ind = 0;
low_ind = 0;
highest = NEGATIVE_INFINITY;
lowest = POSITIVE_INFINITY;
// Find the periods for the highest high and lowest low
n = period;
for(i = index-period+1; i LOE index; i++)
    bhigh = getHigh(i),
    blow = getLow(i);
    if (bhigh MOE highest)
        highest = bhigh;
        high_ind = n;
    endIf
    if (blow LOE lowest)
        lowest = blow;
        low_ind = n;
    endIf
    n--;
endFor
high_ind--;
low_ind--;
Plot1: up = ((period - high_ind)/period) * 100;
Plot2: down = ((period - low_ind)/period) * 100;
