While I totally agree with much you have posted and am thankful for the detailed description of your thought processes, I don't believe in the "I don't like Mondays"-myth so much.
Sometimes it will make sense, sometimes it won't.
If you look at the chart (I simulated the weekly average via MA on M30).
You can see quite well when price comes close to this MA and turns (daily open - im my time zone - for reference) again: there are many entries (on Mondays as on other days) once directional bias is clear...
