ADF Information:

I was curious what the ADF exchange was so did a quick Google on it.

From what I could see in looking at Level II executions, the prices being executed are from the Bid and Sell side, yet I do not see those large volumes being listed at all in the Level II bid listing, hence maybe the reason for what I reflect below. Still not sure how to take the trade executions.

It was interesting to see this in the information: Three sided transactions as a single transaction report, while protecting the underlying clients' confidentiality.
