Trading of shares in a stock exchange takes place through Registered Stockbrokers, Transfer Agents, etc. Investing in the share market gives you an opportunity to earn potentially higher returns on your investment. We invest money in share trading expecting to get profits. When something is done in investing and if it gives a profit, it obviously becomes a business. So, share trading is a business and not gambling. Stock prices are largely determined by the forces of demand and supply. Intraday trading refers to entering and exiting positions on the same day before the market closes. On the other hand, positional trading involves entering a position on one day and exiting it a few days or weeks later. To place an order we need to have a DEMAT account with the details on the share price, quantity, and buy-sell order.
