I put in an order to buy 100k at .0014 and was filled at .0006. I put in a second order just now for 125k at .0014 and they filled 43k at .0005. I suggest if you change the order from 500k at .0007 to 200k at .0014 that you will be filled on the 200k at .0006 or .0007. Then you can enter the second order. It's another commission but it's the best way to do it if you don't want to risk paying .0014. But you will get filled.
