Hi Robby,
Thanks for the encouragement!
FTMO only allows one FREE FTMO demo account at a time for each trader.
If you are using your own broker you can open two demo accounts. Then install 2 different MT4 terminals. During the installation process you can give each MT4 terminal a unique name, like Demo V5 and Demo V5.1, so you can tell them apart.
Hope I have answered your question!
Alan,
