I've been trying to learn more about oil rather than just trading it blindly & had a few questions: 1. If trading CL on NYMEX/CME is there any reason to monitor the WTI Crude trading on ICE? 2. Does WTI trade on any other exchanges? 3. Is there any reason to trade Brent Crude instead of WTI? 4. Is monitoring the Brent/WTI spread helpful to daytrading CL? Thanks.
