Quote from shortorlong:
Ah, I posted the question to the NT guys and got a response (great service always over there).
orders that occur between the bid + ask do not get plotted on the buysellvolume histogram. That is what is happening there.
OK.
Firstly, how much volume can you squeeze between the bid and ask on ES rth.
Secondly, I have counted back similar volume bars on both Ensign and NT and they occupy the same time spans.
Finally, the NT volume histo is stable but the bid-ask is woobly so I do not think we have been offered an acceptable solution by NT.
So I am left to conclude that NT bars are OK for ES at least.
