T-notes are still giving me a hard time

Lately, 10-year Treasury notes have been the black sheep in my herd of traded financial instruments. I have lost 80% of my trades on them since the beginning of 2012. Last year they were one of the most reliable and consistent profit making machine for me. What a difference a year make. Anyway, I am not going to give up on them yet but another couple of weeks like that and I might ditch them for good. Crude oil and natgas were my biggest winners today (not a huge day BTW). In the grains sector, I tried again today, for the 4th time since the start of 2012, to play the odds with a spread trade long wheat/short corn and had minimal success with it. This arbitrage will eventually pay off but it did not correct sufficiently today to make a big difference. I will keep watching it and will one day for sure succeed with it. Other than that, nothing special to report. Net result for today +$634 trading 2 contracts (commissions deducted). Details below. Have a great week-end!
