I agree on the volume of OLB. There seems to be two research reports out on them. One has a target price of $7.00 and the other is over $10.(if the CNBC site is accurate).
At around $4.00-- I am fine with seeing $6.00 in the next 6-12 months. Still, I would be more comfortable with a consistent 50K too 100k in average daily trading volume But the public float is VERY low. Like under 3 million.
