People working in financial institutions, trading houses, or brokerages used to trade in the past. With the advent of online trading, every commoner can now trade. The trading apps are easy to use, and some of them offer 0% commission which has made it easier than ever to invest in the stock market. Day trading is buying and selling stocks to earn a profit in a day due to the rapid fluctuation of the market. Day trading can be a lucrative career, but it can also be challenging for beginners who don't have a planned strategy.
