I felt down at the beginning due to the limited markets available here in the US. I am frustrated with the available settings not working for me, then again I have smaller funds so I can wipe out easily. I am getting close to my working settings with all yhe backtesting I have done. OX securities is the only one to offer a broader option here in the US but their way of funding isn't very convenient. Use either wire transfer or I found moving bitcoin through my wallet was easier, cheaper and faster. I cannot agree with Customer service as I have emailed them as well as OX and have received quick response times within a couple hours. Best of luck!
