No the license is not for 2 people, it is meant for 1 person on 2 different computers, like home and work. HEM also gives you a license for use on 2 computers. I like HEM better, but they are pretty much the same. Try out both of their free trials and see which one you like better, it is really just personal preference. But, the HEM small stakes version goes up to higher limits than the PT3 small stakes version.
* The PT3 trial is better, though, being 90 days compared to 15 days for the HEM free trial.
