After the Nifty fall of 21st December, BankNifty is continuously progressing in the uptrend . I have drawn two trend lines and you can see that the BankNifty is taking support and progressing upwards. Currently, it is at the support and if everything is good then on 28th December, it will break 30500 mark and will proceed higher. First target is 30500 , second is 30800 and the third is 31000 which is indicated by Fibonacci Retracement
