Hey rs59, I had a question for you. If the build was lower than expected, why did NG price drop? I am a little confused about the difference between build and injection, I guess. I thought a build was the level of inventory and if the build increases there is more NG in storage, hence a lowering of prices. Could you clarify the terms build and injection for me? Thanks in advance!
