Is it possible to improve stock purchase with limit orders accounting for volatility?
There is no such thing as buying at the best price. That only exists in hindsight. If you could consistently predict the lower bound, then you would have no reason to waste your time investing. Quit your job and bet with all leverage in. What if the price never reaches your lower bound and the market keeps rallying? What if today is crash day and you catch a falling knife? I'd say the best strategy would be just buy at whatever the market price is the moment your investment money hits your account with the smallest possible commission.
