New N-Day HiLo

This indicator displays the N-day high-low channel as lines and marks any new highs/lows. It recognizes and plots only the first new highs/lows of the day.
For example, If NumDays = 21, NewQualDays = 5 and OldQualDays = 3, the indicator will show the first new 21-day high (low) in at least 5 days, where the previous 21-day high (low) was also the highest high (lowest low) in at least 3 days when it occurred.

Default Inputs

NumDays (7) sets the number of preceding days to calculate the N-Day High and Low.
NewQualDays (0) sets the number of days the new N-Day High is at the highest high and N-Day Low is at the lowest low.
OldQualDays (0) sets the number of days the previous N-Day High was at the highest High and N-Day Low was at the lowest low.
