Teamviewer remote desktop, I don't know whether we can control computer at home using IPhone or ipad, I think as trader if having less time to forex monitoring they can trying as swing trader which making target for medium term, but if they have mobile device platform currenty some broker already use metatarder for android, they can making trades anyhwere and everyhwre as long as can login accountYeah I wanted to do this, and didn't find a mobile charting app that I was satisfied with, ended up using the Teamviewer app (I preferred it a bit over Remote Desktop). It's nice to access your old familiar charting, and the input is not very nimble but it's fine for placing a few trades. And I'm not a phone junkie so I just use ting.com for phone service, I am quite satisfied with this setup...
