There is no information available about a demo account being offered by MARK-E. Demo accounts are commonly used by brokers for forex, stocks, or CFD trading, allowing traders to practice without risking real money. However, since MARK-E focuses on energy trading, it is unlikely that they offer a traditional demo account for practice. If you're interested in testing out the platform, I suggest contacting MARK-E directly to see if they offer any simulation or trial services.
