Every trader probably knows the rule "Trend is your friend", here we see we have a downtrend for quite some time and a lot of rebounds down .. but every trend ends, this one has already taken advantage of quite a few "jokers" :)
This is just a simple trend line analysis.
If the price starts to go down it can go down 20-30% without a hitch. Looks like we're on the border, up or down.
Good luck all!
