1st on the queue but not matched??

[giulio2010]

Hi, all
I had 200 waiting on the queue on the lay side at 5.7, I was 1st in the queue...1000 came after my money but seemed to get matched before me...Actually I can see 4K matched while I was waiting..does anyone know how to explain that...thank you in advance..
On the picture below you see where I was on the queue ( the red arrow) and from 10000 to 14000 while I was waiting on the right of the picture ( blue arrow)

Which market?

Ludl 15.15
I backed at 5.8 and layed at 5.7...my 200 got matched on the back side then I can see my 200 on the lay side as first in the queue, i see money getting matched on both side but not my 200....I managed to close with only 1 tick loss but I should have defenately been matched at 5.7..

On small fields you can be cross matched but I wouldn't have thought that would happen on a 15 runner.

Maybe the order was cancelled and not matched?
