Hi sid4spd, VPS is safe if you have a verified provider for it. Also you can access MT4 on your computer, phone , tablet, iPhone, at home, at work, outside – everywhere 😄 All you need is a device and good internet connection. Regarding the EAs – MT4 allows all kinds of EAs, even if they are self-developed. But here I must mention that for EAs it is also important that your broker gives you permission to use them, because some brokers have different restrictions.
I see that you are new here – welcome, good luck and be patient! Cheers 😄
