Special subsets of day traders include scalpers and rebate traders, who earn money by taking advantage of market mechanics (or try to).
In day trading, your risk per trade is typically the least of the three, but compounding and margin make up for that. The difficulty of day trading, coupled with the risk of loss, is one of the reasons why this timeframe has such a notoriously high failure rate (less than 20% of day traders actually make money).
Swing Trading Strategy
While some sources relegate the "swing trade" definition to those taking less than a week, today's swing traders fit within a bigger window: typically holding for more than a day on average but less than a month.

That's not to say that you should limit yourself to a single strategy. While these monikers are useful ways of identifying similar types of traders, it's not uncommon for some traders to modify their timeframes of choice based on current market conditions -- hybrid strategies do exist.
