Guys, make sure to enable the AutoTrading before placing the EAs on the chart. That is the most common mistake.
The EAs are the same, it does not matter if they trade on Demo or Live. As long as you are with a regulated broker (not a scam broker) and you place the EAs properly onto the MetaTrader platform, all must work fine.
Send me more pictures and details so I can help you out. Anyway, I am guessing most of the time.
