kapla: doesn;t wash what i should have said was that i had been setting with an offer at or above the the ask for several minutes and so my bid to buy should have shown up and it didn,t but trades were going off below the bid and i was not using aon and my order was for considerably more than the minimum to show of 5000 shares.it has happened to me to many times to say there is no manipulation of trading. mrmoe3
