Quote from Duref Mudgins:
I suggest that you develop your own personalized boredom metric, because mine measures the mean boredom of the ensemble of bored traders. So far in my attempts to rationalize the utility of my new invention, I have found that there is a somewhat fuzzy maximum value of boredom attained during the midday doldrums. This indicates that soon nothing will not happen, often quite vigorously, taking the somnolent by surprise. The boredom metric also is useful for determining if la foule believes that the current direction of price is valid or not. I have also seen cases where boredom dramatically decreases with no change in price, indicating that the non-bored know something we don't. So you see, you are better off developing an idiosyncratic metric.
I have one such myself based on the following behaviors, which you may relate to:
the sudden urge to google "(insert your favorite actress's name here) squirrel shot"
inability to resist tapping the ET bookmark to verify for the nth time today that ET is a useless resource for trading
wondering if you can beat your own record and get off six times in an hour
making a random entry to see if money management really does work.
