Hey Zeev...I've had my share of those also...once when I went in to change a limit order to buy 2000 shares of an oil stock around $10, I put in the 1 but in error never took out the 2, thereby changing the order to 12000 shares! And I fillled all 12k, though managed to make out okay over the next few days on it, but surely scared me in a big way! HA!! tuna
