I often violate the trading rule of "NEVER ADD TO A LOSING POSITION".
You with futures and I with spreads. I will add several and you will add several hands full.
In spite of violating this rule, I'm able to sleep well and the small pool that I am managing seems to keep growing and performing well for which I am grateful. It now has a 5-year track record of gaining about 2.5% per month - not particularly good in futures trading circles but when compared to the Dow 30 and the S&P 500, it has really done well since 1/30/11 when it was organized.
There are not many agricultural funds that are outperforming it on Barclay Hedge's list of agricultural funds and pools.
Best wishes,
