Banknifty Fib Retracement Day View

As per my analysis, Banknifty has exactly retraced 50%.
Now for further bullish rally it must take support of 0.35 levels i.e 39600 in round figure.
We do see support at that level, but we also see a strong resistance at 40000 levels.
Moreover i feel market to go sideways in first half and then move in one direction.
