Nifty Bank Nifty approaching crucial levels

NIFTY after breaking out from 17,200 last week gave us a good rally and now approaching key levels of 17,450 . If Nifty manages to cross this resistance , then we can expect a swift move to 17,600 where there is a small gap . And the market might try to fill the open gap.
Similar move can be expected from Bank nifty if it closes above 41,800 , we can see a move of 400-500 pts till 41,200 to fill the open gap.
