Startup Idea: Forex Trading App for Chromebook and Android Devices

Startup idea to develop a forex trading software that can function on Chromebook or android devices, thus replacing the need for traditional Windows-based applications like ThinkorSwim by TD Ameritrade. The software should allow chart downloading right within the app, enhancing mobility for the user and eliminating the common issues faced with Windows computers.

I trade forex currency and have a need to get away from Windows computers. I need to work only on my Chromebook or android devices to be mobile. I need software to replace the streaming currency such ThinkorSwim by TD Ameritrade. These charts need to be downloaded to Windows. o see any apps that would do away with the need to use Windows and all of the problems with anti viruses large computers. I can't really be mobile as long as I have to rely on these applications. Thank you very much. Yes I would pay for this.
