I have re-activated this thread, in the hope that poster "downside" will provide us with the broker names and volume details of October 24, October 25th and yesterday November 2nd, being the three high volume days with the huge price swings in both directions. His info is very good, just take a look at the MNC thread and his post on October 31st.
