BankNifty- Worked twice as channel resistance

One channel & so many benefits- first it worked as resistance at 20264 & gave us a fall of 1000 + points to bounce from 19059 & look the beauty -same channel acted as resistance & BankNifty made a high of 19816 -which again got restricted by the same channel giving us again 1000+ points.

Will it bounce from the channel support? -Time will let us know.
