Stockwatch has a 30-day trial subscription that would allow someone to look at house positions over a period of one day to 6 months.

I've already used up my trial, is there anyone else who can register and give us the information? Ideally we could have someone for each month rather than everyone try just for March. It would be great if we could get people to pick a month from March through to the fall and then have someone report every month.

It would help with these volumes to know if, for instance Anonymous is selling, but then RBC or TD is doing all the buying. Then we might conclude they are trading with themselves.

You need to go to the StockWatch page and select the Free Trial on the upper right and then you can run analytics that include house positions.
