I had a complete 180 week. Last week I got smashed, this week complete reversal plus some. Pretty much sums up the market like others have said. Day trades may have its advantages in the current climate but I'm sticking to what I've learnt and also developing some strategy during these times.

On a different note, I wanted to ask some of the brains trust a question.
In the attached chart there was one day of super high volume with minimal price movement. What could be the reason for this? To me, one theory is that someone wants to mask the the TA of the stock. They buy and sell to themselves which shifts everything and possibly hides other moves after the event. Other theories welcome. Don't know enough as I haven't seen this before but happy if someones puts me in my place as this sometimes happens in an open forums. I'll take it all.

The only  funny that I think is appropriate in the current market. I don't condone violence though.
