Quote from Surdo:
QM is 1/2 the size of CL, not as liquid as CL, if you are even asking this question, trade QM, you'll only lose 1/2 your money!
CL does tick in .01 increments, while QM ticks in .025 increments, making it a little bit less attractive.
QM = 500bbls
CL = 1000bbls.
All off this info is on NYMEX website which is where you need to go.
Thats cause it less liquid. Thus its easier to get your stops hit when it would not have gotten hit in cl. Chart them side by side and you will see the difference, when stops are run qm runs further down or upQuote from MoreYummy:
After watching the DOM for a while, it seems the when /CL's spread is 0.02, compare to /QM 0.025, the bid/ask size 'waiting' on /QM is larger than /CL's bid/ask size at same time.
