If you are speculating in foreign exchange to see the market, Huijin traders are really good. The data is faster, less stuck and more stable. I have been using it, mainly to earn euros and dollars. There is also a VIP version, which has been tried for a few days and is ok, but the VIP version is charged, so I have been using the free version and analyzing it myself.
