Hard to say...I usually go off the old adage that gaps will be filled. I mentioned something about that way back down near 840...that gap still hasn't been filled. They worry me even though I've seen gaps stay for years.
The ideal test of a line is one that will just touch the line, or get to within a penny or so, but not go below it and especially not close below it. Having said that, I've seen it do both and still continue up...touching it is just the ideal test.
The best place to buy, IMHO, is close to the line of nine. Thinking that's a good place to be proven wrong quickly and cheaply. How far under the nine line to put a stop loss is at each persons discretion.
Like I said earlier...I was expecting a totally different pattern that did not/has not developed. It's gone up quite a bit, already.
