Avoid Sunday bars...

Hi, the attached indicator plots previous day high and low (with other indicators).

Is there the possibility to avoid Sunday bars?
If Monday, the indicator should look to Friday values, not to Sunday evening values...

Thank you!

Finally I seem to solve this problem with the attached indicator.
I add this condition:

( TimeDayOfWeek(Time[i+1])==2 || TimeDayOfWeek(Time[i+1])==3 || TimeDayOfWeek(Time[i+1])==4 || TimeDayOfWeek(Time[i+1])==5) )

in the initial IF condition.
