I'm new to spread trading. I shorted RB, HO, and CL yesterday and have nice profits in them. I also sold some spreads on them. The RB spread was very profitable, (RB is the weakest of the three). HO was profitable and the CL spread was barely profitable (Crude is the strongest of the three)- it barely moved despite Crude dropping from 94 to about 93. I wanted to know if someone can explain why this is. I sold the RBH3-RBJ3, HOG3-HOH3 spreads. The Crude spread I sold was CLG3-CLZ3. But I looked at almost all the high volume, tight spread spreads and most of them are unchanged or up! I decided to sell CLG3-CLZ3 as opposed to CLG3-CLH3, or CLH3-CLJ3 because from my observations it seemed like CLG3-CLH3 was not moving much whereas RBH3-RBJ3 and HOG3-HOH3 were. Any advice/explanation here would be very useful. Thanks.
