Quote from Ol' Yella:
In my opinion--- NO.
Even if you can get into the 1% who are profitable, you will have to make a LOT of money to compensate yourself for all the stress, uncertainty, lack of benefits, lack of access to credit, years of unprofitability before you "made it", etc. Not to mention all the continued effort to stay in that 1% year after year after year.
I think this idea of an average person daytrading from home for a living is an internet urban legend.
If you're already wealthy, or if you have sources of passive income, or if you work a job outside of market hours, or if you have a wife who earns well and provides you with benefits from her job--- maybe then you could realistically look at having some of your income come from trading.
Otherwise stay in your job or look into starting a business, ditch the videogamer stuff and trade longer term while earning a living elsewhere. If really interested in daytrading then at least get affiliated with a firm, or learn programming and get into HFT, just stay away from the retail education side of things, nothing but snake oil there.
