bank nifty in a flag pattern (big fall or big up trend possible)

I did multiple time frame analysis in bank nifty. and I am trading bank nifty for roughly for 2.5 years now so i am really comfortable with this index, so I can predict graphs and movements easily so here is what I found in my bank nifty analysis, I saw that it is forming a very popular pattern know as FLAG which usually means that market is going to be on bulls side. but, in this patter there are multiple supports and resistance involved in it. so from my analysis if tomorrow it opens gap down we can short market for big selling target or it can give us a breakout retest the trendline and gives us big target to achieve. you can check the photo of my analysis from link below
