Trading is the buying and selling securities, such as stocks, bonds, currencies, and commodities, to make a profit. And success depends on a trader’s ability to be profitable over time.
Investors try to forecast market price movements and profit from buying or selling an asset at a higher or lower price. You can ‘go long’ and buy a security, hoping it will go up in value and give you a profit, or you can ‘go short’ and sell in the belief that it will go down in value.
