A doji at the top in Nifty. Reversal?

22nd April nifty daily candle formed a Doji at the top of the rally. It's a sign to be cautious. We can see a retracement of nifty back to 24121 (Spot) which is a fibo level. Once it touches that we can see what will happen next. Even a gapup today don't be bullish and be watchful of price action. With bad news coming through we can see a retracement happening.
