Thanks for the advice. I'm watching the 50% intraday retrench @29.14 (it just failed at the 61.8 retrench). If that's taken out, I'd probably cover for a small gain; but if not, I think it may slide further.
Note COMP has not/cannot bring itself above the 61.8% intraday resistance @1542, yet.
Although SNDK is still trading relatively weaker than the indexes, I just scalped it for 70 cents gain. Don't like the fact that COMP broke above its 38.2% intraday retrench.
