The Tuesday Problem

The Calculator is working really well. Except for Tuesdays. Actually, it was Wednesday last week, which was the second trading day of the week. I looked back at previous results, Tuesday predictions were the most common day for me to state in my notes that the calculator was just wrong.

I often focused on Mondays as an issue day of concern because it’s days after the day the prediction is made. However, when I run the prediction for Tuesday, I’m using Monday/Friday data. Monday still uses consecutive day data from the previous week. That gap seems to be a big issue for accurate Tuesday results.

I’m testing, I’ve taken the first data set from early morning rather than end of day Friday. So far it seems to be a good solution. I’ll know more in the coming weeks.
