I know I should have picked this up before, but I guess I haven't.....Other than the fact the transactions were above the bid, what does level 2 (or whatever)show you that indicates the transactions are purchases.
In asking that, I am very aware that each transaction is both a buy and a sell, so I assume that by stating it was a buy, you feel that it has been a purchase out of a MM's inventory.
If it's not time for a lesson, just tell me to bug off. Rich
