Banknifty..trend changed?

Last two weeks have been quite bullish..was this unexpected? No price action was very evident

Now coming to today, bank nifty is stuck in a range as marked in the yellow box..
One thing to note is the channel has been broken and makes me stay aside and asses this bull trend..
As you can see..bank is making lower low from last days….waiting for the lower level to get broken…and will short on any pullback on lower time frame
