Hi, you will need access to a computer in some form to be able to trade EAs. As a minimum you would need a cheap VPS such as the one from contabo which starts at 5.36 Euros a month and a cheap laptop that can login. Powerful expensive computers would not be required to run the EAs from the app. Even a chromebook would do so you can login to your vps. And minimum deposit depends on your broker but typical 200 dollars would be the minimum
