They are big market cap stocks. JP Associates, adani, suzlon , rcom are stocks which see huge turnover volumes. They are not penny stocks. They are highly liquid stocks.
I have accounts with other brokerage companies like aastha which provide very high margin too. I dont trade much on zerodha these days because many times Pi crashes up in the middle unable to handle high data traffic.
I have 16GB ram , core i7 . And my trading size is not big. I want to trade atleast 10 lots at a time. And no I am not satisfied from my profits. I want a big move in price.
