Tech View: Nifty forms a Doji candle. What should traders do on Wednesday

​The immediate resistance for Nifty is at 22,500, and a break above this on a closing basis would signal a resumption of the upward movement. Conversely, the immediate support is positioned at 22,200-22,150, and sustaining above this level could witness some recovery in the index, said Kunal Shah of LKP Securities.
