You shouldn't be hedging a 100k account trading futures anyway or were you spread trading(looks like your understanding of spread trading was backwards if you were). That is exactly how all the hedge funds that blew up the past couple years did themselves in. Secondly you need to better understand executions, price history, and fills. The Euro never traded to 1.60 so it looks like you have been screwed. It also looks like you may have gotten screwed on a couple of your long trades as well. That is a hellacious spread between those contract months and it just doesn't look right to me. You need to get on the phone ASAP...you should have some money coming back to you and possibly a legal recourse as well.
There are price differences in longer dated futures contracts vs the closer months. To see this for example, create an Oct chart of either CL or 6E and a Dec chart, the prices will be different.
