Are you buying at each Dip?

Hi, I want to know if you are buying each dip (more than 0.5%). I have stopped doing SIP and buying at each dip, like when there is a fall of more than 0.5% - 0.6%. So is this a wise thing to do like will it make any difference? I have the capital and don't want to miss this opportunity. I am not thinking of returns now, just keep buying good stocks.
