I have read somewhere that market makers at times will take out stops first before making the move to the other direction. For example, before a stock moves up, the sell stops just below resistance are first taken out before going up. I am thinking this could be the reason why sometimes after I bought a stock near support, the stock goes down, takes out my stop which I thought was placed at a safe distance, and then moves up leaving me behind. Can anyone explain the logic of this strategy by market makers? I think it is important to know how market makers and professionals behave to be able to play decently in this field. Thanks.
