heres the thing, when you buy more, to average dow

heres the thing, when you buy more, to average down, you should sell your higher lotts for a write off, trade you worst buys, for your best buys, and do it every 31 days, why? this way you lock in your losses, the 13k you are down, could be used for taxes when you are 13k up, see its like playing both sides, when you make money 40% goes to taxes, right now you must take advantage of the red, so you dont pay capitol gains, i used to just watch the red numbers in my account, never sold while down, only to go up, and have to give 40% back, so every 31 days i am shifting my money around, curious what you think of my trading ideas
