I'm incredibly dismayed that this tea-leaf reading practice is taught at major universities that are otherwise quite credible.
it's even taught at Cambridge university: https://www.mrao.cam.ac.uk/~mph/Technical_Analysis.pdf
This is giving credit to fortune telling, not science.
Yes, i agree with you, Prometheus, such definable time-period influences are valid (ergo: the christmas shopping season and toys, winter and salt sales for the roads)
however the teaching is that price and volume strictly from the chart tells you all that you need to know.
i find it highly suspect that 702,454 people sold their stocks in July just because 909,134 people bought stocks in January.
yet this is taught at every major university and business school.
disconcerting.
