Banknifty support at 45785-45658 (Futures)Banknifty futures support lies at 45785 and fibo 61.8% level is at 45658. This fibo is 1 day candle level which ideally should not be broken and we should see a retracement back to 45459 or 46260. But if it s broken then we have support only at 43924. But as per the fibo concept we should take support . So ideally if we touch 45650-45750 it would be better to book profits on short side and wait and watch for a day to understand where will we close.
