Agree, mostly. The one advantage of being a small trader vs. the hedge funds is that your trade blocks are too small to swing prices, so you can get in and out of positions quite easily. I would definitely also not recommend day trading per say, a timeframe of 1-5 days per trade is IMO better as you can actually see a decent swing in price.

It is possible to win, but you need to be good, and most people who do it in their part time simply don't have the knowledge or experience required...
