I've tried day trading several times, and swing trading (this is holding a trade from say a day up to about a week), either broke even or lost a bit every time I tried. Trading short term is extremely difficult, very few people (maybe 1%) succeed over the long term.Years ago, I tried day trading for about 4 months on CMC, mostly on currencies and market indexes. I did OK for a while until I got fleeced.
I eventually realized that investing over the long term using global indexes and professional managers such as Terry Smith of Fundsmith Equity was the way forward for me. If you can put money away and not draw on it for at least 10 years then the chances are you are going to do a lot better than having it in a bank account where due to the low interest rates you are probably going to lose out to inflation.
