Quote from Humpy:
Some pretty deep stuff in this thread. For my tuppence worth:-
You have your relevent inputs and think of them as charts probably, in 2D.
If you can expand this to 3D you will have made a quantum jump.
During trading, it has been helpful to visualize an auction market where floor traders are going about their business. Sometimes, a scene or two from 'Trading Places' also slips in. Is this the 3rd D?
