Banknifty - Sideways to Up tomorrow

Banknifty today (13/7) formed a good bearish candle and broke the below trendline cutting the bullish trend. But it went till an important low (support) of 21982. HDFCBANK similarly took an important support near 1066. Kotakbank not yet seem to be bearish and in sideways direction. Axis bank took a good upward candle. Indusind, IDFCFIRST and Bandhanbank dint go much below yesterday's low. Taking these factors in consideration banknifty tomorrow my range till 22400. Even if it breaks todays low, i see 21700 as a support level. Please share your opinion.
