Good afternoon everybody (EST) . Waiting for the FED decision. I am currently using X-Trader as my trading platform and have a question? When you login to X-Trader there are numerous tabs at the top of the of the TT Exchange login box. For instance on the CME there are tabs for .... CME, CME-A, CME-F, CME-G, CME-C. Does anyone know why this is? Does X-Trader (or broker)assign traders that trade more contracts to different tabs (connections) that are faster or more secure? Just curious. Thanx. Have a great day everbody !!
