I was a technical trader (using charts and hard data exclusively) as opossed to a fundamental trader (using news that that sort of thing). The only importance in that tidbit of information is that a technical trader uses charts & graphs extensively. I also used various pieces of software. One of the primary means of predicting the ebb and flow of markets was using the Fibonacci Numbers. Here's a link to the detailed description but honestly it's waaaaaay too complex for the layperson: Fibonacci number - Wikipedia, the free encyclopedia In a nutshell, there are some observable patterns in the physical universe and some of these patterns are considered to be "perfect" or "beautiful". The coil of a snails shell goes in a perfect spiral. Note the little boxes, which also follow these patterns or ratios.  If you look at the florets spiraling here you can see these ratios in play as well.  So the number that is most relevant when I've brought it up is called the "Reciprocal Fibonacci Constant" or 3.359885666243... Let's just call it 3.36, which is just slightly more than a third. The other number would be the opossite piece of the puzzle at 6.64. So you'll find very fine artists are well versed in these numbers and you'll see these ratios expressed in their art. It's about the most scientific system to denote what is considered "pretty" or "right" within the subjective world of beauty. Here's an image showing placement of things all within the Fibonacci numbers:  We used these numbers in looking at the up and down motion of charts. Noting the swing up and "predicting" the amount of swing the other way. In a perfect world you could predict the ebb and flow of the market with great regularity and it would work out short as well as long term. I then ran into them again when working with an artist. We were friends and he mentioned Fibonacci and how you'd find it in his art. We spoke about it off and on for some time and since then I've tried to notice it more and more. You'll see it in the arch of a swans neck, the ripple in water from a stone being thrown in, etc. and these ratios/equations help an artist paint something "correctly". Anyway, Eric asked me what the heck I was talking about so I thought I'd explain myself. Yes, he knew the sequence but it was probably in math/history, not in an art class where he learned of it... |

 We like curvy things cause of boobs. Then someone had to go make a mathematical equation about it. This is why we call them "mad" scientists  | |

| Junior Member  | I always associate Fibonacci numbers with Mandelbrodt Fractals...so cool. Fractal - Wikipedia, the free encyclopedia   See the spiral...? |
