I would cover on a back-test of the falling support line connecting the Dec. and Jan highs, which I estimate is around 18.80. However, that's just me.
TNX is just sitting there right now. I think it will explode up on Friday's GDP. It needs another high, and it's building a bull flag that measures to a test of the Dec. highs. That will drag some stocks up with it if that happens, and will probably Dow move up quite a bit also.
