Couldn't agree more. But it's also a fact that DCA is for position traders (those who prefer long positions). Definitely not for scalpers, day traders, and swing traders. But ultimately, it's not the technique that would cause you to lose more but taking risks you can't manage and spending more than you can afford.
Well yea, DCA is for long-term investing and was never meant for trading in the first place. Not to mistaken DCA from doing TWAP (time-weighted average price).
