I'm trying to add to my DSS position, and I'm gett

I'm trying to add to my DSS position, and I'm getting a taste the big players with their algos that can front-run a retail order. With the bid at .27 I put in an order to buy at .2701, but then the bid suddenly jumps to .2702. Then I up my order to .02704 and the bid becomes .2705. The system as they have it rigged won't let me be on the bid. Darn algos!
