The idea of this chart, if we look at the price of the date 14-15th of August, BTC price should have gone lower at 5.4k, but stopped at around 5.9k! The opposite is the the last 7.4k BTC reached on 3rd of Sep. It touched the line! Wouldn't it be a very bearish sign if BTC stopped at 6.9k and turned down? The line drawn is an idea, that shows the bears can't push the price down as they may like! The bears should push the price to 5.2k if BTC is to move inside the bigger lines. Even that, it's a matter of time that BTC price will move out of these lines of 7 months now! My opinion is up, after MT-Gox coins are sold, i think BTC will slowly start to move up! Anyway, it's just my opinion! Good luck
