I used to play that way too. I'm no genius, but I do like Warren Buffet's methodology of buying and selling a specific holding over time and never all at once. Sure, sometimes you miss out on a potential gain but other times you save yourself from an ugly loss. And for me, there's nothing in this game more satisfying than when a stock takes a tumble (goes on sale) and I have the $$$ to average down or simply buy in cheap. GLTY
