I was wanting to daytrade some DRL and to hold some longer term. The bid was 16.00 w/ 100 size; the ask was about 16.13 with shorts showing 1300 shares. I entered my order one cent below the ask, and the shorts matched me. When I saw that happening, I kept reentering my order one cent below the shorts who kept matching me. Along the way I sold a couple hundred shares at higher prices, but eventually bought was able to also pick up the 1,300 shares from the shorts at a reduced price of $15.98!
