How does drawing a teacup on top of a chart incorporate "all currently known information" about anything whatsoever?

The collective knowledge and opinion is dynamically reflected in the price and volume chart.

Because you are not drawing a teacup, you are looking at price patterns. IF you believe in efficient markets, price should be an indicator of "all currently known information"

If you believe in efficient market and things being priced in then there is no past price information that can affect future price as future price is entirely martingale. You can’t both believe in technical analysis and in market efficiency.

Burgers' equation models traffic flow. Traffic comes from humans and humans behave in patterns. What difference does it make if it's a PDE or a teacup?
