This is what I learned the last several months. Please add your suggestions to the discussion. 1. Get enough sleep & rest - tiredness lead to mis-perception of risk. 2. Eat right - don't trade w/o some breakfast. 3. Exercise & meditate regularly to maintain fit body with calm mind. 4. Get a life outside of trading. I grade my physical & emotional well-being as well mental preparedness before each trading sessions. If I am not up to snuff, I go on sim or simply take the time off. There had been previous occasions that I forced myself out of bed for the Nonfarm Payroll jobs report only to take insane trades. Once, I even mistook a live DOM for sim. So no more trading tired or sleepy for me. I am in Pacific Time Zone, getting up in the pre-dawn hours is quite a challenge for me. I am still trying to be a morning person - I am not there yet. Trading has forced me to put in the effort to maintain personal fitness more than any time in my life.
