Long term Commodity trading "system" is 5-15% winning trades based on original entry trade as it seeks to get in first at tops/bottoms, so I just got use to losses, but just cause you lose in futures, does not me you are losing on position. I learned an idea from chatting with a trader that worked for a Commercial trader ADM, that few minutes of chat, had a rolling affect on me in 1992, I greatly improved it later in options and every few years it gets better, but it always stays no greater than 5-15%, and I am very happy with what I have developed.
Whereas in stocks/ETFs, I will take positions at extremes counter trend, but have rigid rules and they based on chart patterns or patterns I have discovered. But most of trading is trend. But I have learned great deal about hedging on my own, first in Commodities then others.
I wake up each morning extremely confident of what I am going to do, it be like anyone been doing same job for 39 years making widgets, the only complications that exist is boredom. This confidence means to me I WILL be right on any trade I take, now whether it is profitable or not is not my concern as I am just following a set of rules. You have to learn don't take losses personal, just take them and go onto next trade.
If you don't have desire to be right, shouldn't trade.
