It is Interesting to Reflect, from Victor Niederhoffer
It is interesting to reflect that out of 37 open market meetings since the beginning of 2009, 11 have closed the day before at a 20 day high versus just 3 at a 20 day low. That might seem unusual without the knowledge that since 2009 there have been 292 separate 20 day highs and only 95 20 day lows. Thus 25% of all days have been at 20 day highs since 2009 but 30% of the open market day precedings have had that honor. A most insignificant but interesting difference and framework.

I had a long discussion about this with someone internally yesterday.
Writing and "doing" concurrently in a team is a very difficult organizational exercise, as ideas and implementation folks have different time frames frequently. I've seen similar dynamics with pilots and racing skippers with their navigators.
Steve Ellison adds:
I found that even talking about my trades introduced subtle motivations that I did not believe to be performance-enhancing.
