Right, the trader cant see if it is an AON specifically.
What they can see, is if they are trying to buy 500k of those 1.3Mil...and the order goes unfilled for 30 mins.
...and then I moved my buy down to 100K to see if it would fill and didn't.
Good indication that it is an AON to me.
It's possible that it couldn't be, orders could be slow to fill, or the way that multiple orders are waiting, my order might not have been fillable.
Lots of possibilities, but more likely that a Trader wanted to sell all and couldn't in one order.
Especially when the previous ETRF order for the exact same amount of shares went off at once.
