There are also mathematical chart patterns where precise measurements of parameters are possible for any group of securities. Here is a tool that finds those and determines their statistical parameters.
HFT which dominates the market knows nothing about chart patterns.
Incorrect. An algorithm will operate within a finite framework.
The main man for DSP in trading is John Ehlers:

Easy edges is a loaded question. I have found an edge that is very easy to trade. It took significant time to identify this edge. I'm sure there are many more similar to my setup.
I've trade it since 1998, average 2 trades per year, average 41% return per year.
When one identifies a real edge, the emotional part of trading fades away.
Best of luck to all.
Have you some evidence that a "double bottom" is an edge?
There are no real studies that have been made on such patterns , when i say real study , i mean a study over a huge sample of charts that give you all the statistics for trading such patterns , i'm afraid giving 10 or even 1000 examples isnt really enough ...
