Hi
I am new to this forum. I have not had experience with CMC options, however, I work for IFSCL USA, which has a streaming options trading platform. We offer "live" auto executable prices on spot
fx for fixed expirations. For any other dates, you can do an RFQ. The shortest time frame can be 1 week and all data is made completely available. These are two way prices, so as long as you have appropriate funds, you can sell options as well. We are an FCM located in NY. If you have any other questions, you can visit our website www.ifsclusa.com.
Thanks
