Todays market is 20% retail traders. These types of days with high volume come from HFT activity. The mathimatical formulas search out cluster orders and take hold, Automated computer trades is the driver on these days along wihe retail traders jumping in. I sold Friday because of Thurdays high volume and I didn't see price rise in harmony with the high volume. Usually not much happens the following day, but I stand waiting because also with the follow days high volume it could have shot up. Will it Monday? I am unsure. If you have high volume in the morning, it is very possible that this can shoot right up to $10. It is just too hard to tell, so I took those profits.
