Technical analysis is an another form of manipulation.
Your point being?
TA ist hokum.
Trying to find patterns in random walks has the same, solid, evidence-based foundation as
- Astrology
- Homeopathy
- Dowsing
- Clairvoyance
etc., etc.
If anything, not TA itself is manipulation;
selling TA to others is.
