Transparency on the rise in Europe

What happens when some of the biggest institutions in Europe decide to redirect  their order flow from market centers that they feel are compromised?  Change happens.  In addition to some major European exchanges changing how they publish order id information, this morning we see the news from the FT that that six major investment banks in Europe have “voluntarily” decided to report volumes that trade on their dark pools .  They will only do this at the end of each trading day and not in real time.    It appears that this move was also in response to the demands of institutional investors.  Our European counterparts smell a rat and they are pressing for more transparency.  Now, maybe we could do the same here in the U.S.
