Hi
I use bitcoinwisdom to keep an eye on price. Trouble is I dont fully undertand how it works. For example if I look at the MTGOX price it looks like its still trading.
Why isnt the line flat lined?
Is there somehwere I can go and learn what all the lines on the graph mean too

Like the ones to the far right that come off the end of the main graph line and split green going up and red going down plus a grey one in the middle .
Cheers
