To those who trade for a living, day after day: what do you do when you are under the weather? Stay home (or if at home, turn off the computer) or brave it? What about during a volatile market, when there is much more potential? My feeling about it is that trading is like fighting, and I am not going to step between the proverbial ropes and risk my hard-earned capital unless I am at my best. If I cannot think clearly, I should not be trading. Rather, I should get better so I can get back in the ring as soon as possible.
