BankNifty is trading between support and resistance zone but it is still in bullish channel so trading on buy side has high probability.
We can go long when price starts reversing from 51850-51900.
Trade only when price comes to support zone for good risk to reward and high probability.
Note: Its just an analysis, wait for the price to confirm.
Disclaimer: Always follow risk to reward, this is the only key to success in market, no matter how much good a trade is looking we never know the future.
