No all the nifty 100 stocks are not liquid , better you can find the stocks with latest good turnover from nse site in options segment . Even if the liquidity is less than normal then prefer having a max slippage or 1-2% or you will be missing out some of your profits . If you're getting more slippage than that , it is better to avoid the stock because low liquidity may lead to making the exit hard too . Hope it helps
