Hi Arijit,
If you are considering only these data points then I don’t think so you can conclude anything here. Unwinding in option chain doesn’t always indicate a buy signal, there are so many other data points to consider like volume, IV for overall analysis. Secondly, with volume you should also check delivery % and the price action.
For swing trading I will suggest to check the trading set up’s Nitin sir has suggested like divergence, trend lines, fibonacci, support resistance, Price action, Stochastic RSI and Heinkin ashi. According to me there is no buy signal at this point in time on any setup. May be this view will change tomorrow.
Hope it helps.
