Nifty has made a hammer on 25 October 2021 at its curial support line. Now, since the hammer at its support line, as per the technical analysis, its a sign of reversal of the trend and hence, I will be considering this as bullish pattern. The pattern will be invalid if the Nifty break lows of 25 October 2021.
