I'm not a day trader, except that on rare occasions I will buy once and sell once a specific stock on the same day. [My account doesn't even allow me to do any more day trading than that, or even "pattern day trading" - my account has no margin.] What I want to do is reduce the cost basis of my shares (to below 10 cents/share) and that can only be accomplished by selling some and then buying more at a lower cost, and then holding the lower cost shares.
