Sometimes, people just carry on trade without asking what commission is for? Last time b4 got online trading, brokers must do paper work & stuffs, but today with the technology available, nobody ask why still give commission to these brokers. They are not earning from useful services.
In fact, there is a serious flaw and impairment in this commission-based stock trading because whether stock value is positive or negative for the stock holders, a broker enjoy commission. A broker can encourage a negative and disastrous market and still reap commission from the stock meltdown. In principle, a online broker is handed a virtually risk-free business made in paradise with no duty, moral and culpability to give service.
Broker commission should be exterminated as it has become a meaningless give away of money.
