Getting filled right away

[alanm]

Where was the order routed, and were there any other bids from that route at the time?

For example, if NYSE was the only venue at the inside bid, and your order was routed to ARCA, it's entirely possible that someone chose to hit you on ARCA for an instant fill instead of sending it to the NYSE, where they might not get filled.

It was TXN 100 shares going long at the bid.... I know 100 shares isn't a lot but I am just trying to figure out why I was filled ahead of all the other L2 quotes. My understanding is once you send the order you are put in the back of the line... All the other people sitting at that price must get filled before you before you get filled...

Hidden Island or hidden Brut perphaps.

the order was routed to brutdot and not sure if there were any others. The fill was as soon as I hit the enter button though
