1208 days it crossed the PDH. Among those 1208, 691 days it closed above the PDH.
But, in all 1208 days , the sum of close-PDH is 10921.

Nifty crossed the PDL.
1083 days it crossed the PD low. Among those, 605 days it closed low.
Sum of PD low-close is 14113. But, we should look for failure too. One day it was -416 points.
