Here is a couple of more charts from my corrected data There is a lot of action happening mid-day (middle bars), it contains more range and volume than other periods. You just got to be very patient to capture. When someone says "there is no money to be made mid-day", its more a statement about that trader's patience rather than anything else. I will be the first to say that I suck at mid-day but now I have confidence that the problem is not the market, the problem is me
Here is the new data if someone wants to play around with it or to find a mistake https://1drv.ms/f/s!Agci7SoUSjUwwWsySkQX4uaM_gWg Barring someone finding something new it seems to me that the conclusion is that the Open and the Close are like trading on fast forward, things happen faster (in terms of range and volume), during mid-day there will be plenty of things happening in terms of range and volume, it just takes longer. So its like trading on slow motion. I used to take comfort in leaving the desk during the mid-day because I thought 'nothing will happen anyway, there is no range or vol'. Not so, if I expect a move to happen at some point, it might well happen mid-day, even if a tad more slowly. I still like the idea of leaving mid-day for lifestyle reasons but at least now I'm aware of all its cost and benefits
