The Nifty 50 nosedived sharply and erased all its previous day's gains, correcting by 1.4 percent on January 21 and forming a long Bearish Engulfing candlestick pattern on the daily charts, testing the downward-sloping support trendline intraday, indicating weakness. The index has broken its 23,400-23,050 range on the lower side and closed at 23,025. Hence, if the index fails to defend the 23,000 level in the upcoming sessions on a closing basis, the selling pressure may extend towards 22,800, the immediate support, followed by 22,600 as the next support. However, on the higher side, 23,200-23,300 is the hurdle zone, according to experts.
