I don't day trade. However I am an investor, and I think that it would be wise to consider that if you attempt to day trade you will be competing with entity's with deeper pockets than you have who have spent fortunes on computer infrastructure and programming, and they are intent on taking your money.

On another point, I think tax advantaged plans are great,however I prefer to use them for low risk assets because capital loss's can not be harvested, and even the most successful investors have loss's.

It is very hard to beat the market consistently. People who are much more clever than I would say that to attempt to do so would be a fools errand.
