Quote from PAPA ROACH:
I'm not saying you can't make any money with UNG, I guess I'm saying it is an inferior tool for a proxy to natural gas. If you want to trade the fixed price of natural gas, open a futures account and trade that, it's what UNG is doing except they are charging you a fee and they have layed out their roll for all the real traders to make money off of like vultures (front running).

Quote from Landis82:
And this is what is happening with the USO as well. Due to the contango configuration of the market, each time the Fund sells the front month and rolls into the next month, they wind-up losing another $3.00 on the spread.
Some of these ETF's like the USO are like a freaking Ponzi scheme... AND they even tell specs when they are going to roll too.
Just outrageous!
Quote from CET:
I was just thinking the same thing about the roll. They need to stop telling when they plan to roll. UNG is supposed to begin rolling tomorrow, but if they did not do it today into this volume they should be shot.

Probably a pretty simple question, but is there a convential formula for calculating the difference between CL - NG? Is there a way to calculate them on an energy equivelant basis?
