Basics of Stock market

Hi,
Your Question 1 :: Equity has any time limit to buy and sell ?
Intraday trading is typically completed within a day – this means that you have to sell the shares that you have purchased on that day before the closing of markets. Even if you don’t sell the shares by yourself, they are automatically squared off before the closing. On the other hand, in delivery based investments, you are not required to buy and sell shares within a day and you can hold them for as long as you want.
