Hi! I was bidsitting there last week, without success, so I guess should have paid the ask :-(
My attitude on NGMC right now is that, being up 350% on the day, I "missed it." I'll pass on it for now.
I do buy on technicals, looking for unusual trading activity, and buying if the chart looks and feels right. I specialize in "sleepers," finding companies where I've discovered changes in the works, and then buying and waiting, but only if it has a low share structure. I've been waiting on some for months. Sometimes your train never comes, though :-)
