As promised in my previous posting here the ZeroVersion 2,01 of my ExcelTicker.

OK,
I am seeing a couple of things on DAX with IB that concern me. DAX is pretty thin so should have no problem keeping up. Every now and then I get a tick with 100's if not 1000+ contracts. This is like getting 1000 on ER are YM it hapens a few times a day. I guess it must be due to aggreagating (Does Eurex aggregate ? I believe so).
The wierd thing is that this often leaves the bid and ask unchanged. It's like a block trade.
Strange.
