Sounds like you just bought 3000 shares instead of 1000, and more often when you DON'T want them.
Never saw this post back in Feb. but I should have clarified that I do this when I am closing a position and closeout orders are OCA orders so if one fills the other live ones are automatically ded at that instant.
