Globex hiding trade size?

[andy2001]

I read that sometime back globex changed the way they send data which they claim gives more information. I’ve also heard the change make it harder to track large trades. Looking at the time and sales after hours I often see a bunch of order at x price hit at the exact same time. Would I be correct in concluding that they are often a single order broken down for each bidder that filled them if they hit the bid for example?

Might be something like an iceberg getting filled...

AFAIK they switched from reporting the aggressors size to the breakdown of limit orders that filled it.

eg - sweeping the offer of 10 lots would show up as the 2, 6, 1, 1 that comprised it.

Well this sucks for software trying to find big trades.
