DislikedAi-ya Gilmore's a good read, his take on Gann squaring is mainstay with many and written in an understandable text. Cowan will give you headaches, but a different approach as he looks at the markets along similar lines except on an elliptical 3D basis.
It was mentioned earlier, you can get as deep or shallow as you want when digging into these types of analysis. One of the best traders I ever met, used basic time/price and some simple geometric analysis mixed with good money management....Ignored
By the way, is there software that analyzes price action in 3-D or other dimensions? Do people trade that way, do you know?
Take care,
