Just for information purposes. I decided I wanted to buy another 3M shares in my retirement account on E*Trade. I put in for .0001 and it filled the order, but it was at .00005. I decided to go ahead and try again for another 3M, but it filled that order at .0001.
When it filled the order at .00005 it showed a red 0 and the 3M beside it. Not sure how, but I will take it and hope that I did not make a mistake by going on and getting another 3M.
