I take a minimum of stuff with me, but I always have my phone with me, and that's enough — I open https://play.google.com/store/apps/details?id=com.roboforex.webtrader&hl=en , do a quick market check, adjust my trade settings, and go back to relaxing. The app isn't overwhelming, and the interface is easy to understand even in sunny weather when the screen is glarey. This makes it easy to combine vacation and trading without any extra stress. I don't spend a lot of time on my phone, but I always know that the situation is under control.
