Hi Strobeman,
I am happy to help you with any and all questions you have to get you going. Just fire away with your questions! I am not sure what email you are referring to but here is what you need to do. First of all it is recommended that you test the EAs in a demo account until you feel confident the EAs are profitable. Keep in mind that all EAs, just as manual trading, will go through a period of profits and a period of losses. The goal is that over the long term you will be profitable. I had to say that so that you don’t get the idea that EAs are always generating profits. Nothing is perfect!
Now lets talk about MT4. If you are going to have more than one demo account you need to have more than one MT4 platform installed on your computer. I have multiple MT4 platforms installed on my computer. I give each installation a unique name so I can tell them apart, such as, demo1 and demo2.
Now about VPS. You do not have to have a VPS. If you are going to install MT4 on your computer then you will need to keep it running during the trading week. If you decide to use a VPS the VPS I use I can run four MT4 platforms.
Hope I have answered your questions, and I am standing by to more questions when you have them.
Happy Trading,
Alan,
