They're trying to change it to suit their own agenda.
There appears to have been some frenzied action late yesterday as well but I wan't watching.
The opening price today as reported on the Clark Moody website is $68.49.
Earlier today we saw a series of unexpected huge purchases right off the order books raising the price in total by more than $20 to a high of $98.77799, then it stopped.
Next various ask walls popped up, the largest of which is on $70, right now someone wants to purchase 22529 Bitcoins at $70.xx
Why is that ? I suspect it's solely to protect the closing price, if it closes lower than the opening then it's a red candle.
So in conclusion I'd suggest that the madness today has been a battle between the people who want the candle to be red and those who want it to be green.
A forced green candle at this stage isn't going to be a good thing, whoever's doing this has spent a lot of money and I have no doubt that there's little atruism in their intent.
My prediction : this is a large scale bull trap being laid out before us.
Maybe I'm wrong but that's the way it looks to me.
So when the market goes down $40 in a day it is a "correction", but when it goes up $25 in a day it is inexplicable?
The real truth is easy: there are more people who want BTC and think the price will go up than those who think it will go down.
