I see someone has posted the daily trades, see link above.
Biggest seller on the day - House 80: National Bank @ 25,400 shares sold
Biggest buyer on the day - House 44: Jones Gable @ 30,000 shares purchased
The national Bank dump @ 3:45 is what caused todays dip. Easy to drop when someon puts up a 30,000 block for sale when volume on the day up to that point was 28,000
