Fibonacci ratio is a technical trading system based on mathematical laws of nature. If you measure the spiral in say a conch shell, there are distances measured in specific ratios typically 23.6%, 38.2%, 50%, 61.8%, etc. With respect to it's use in investments, its like any other investment tool - in hindsight it seems to work very well, but our own penchant for confirmatory evidence causes us to ignore the times it doesn't work. By definition, if fibonacci analysis on Natural gas gave a risk-adjusted advantage, more than likely everyone would use it and it would cease to work because by using it, nat gas traders/speculators/users would change the price dynamics.

Rockman - stick to your fundamental knowledge of nat gas business -too late in game to learn some esoteric trading algorithm - but the universal nature of these numbers IS of interest (outside of financial markets). Just my 2cents.

Rockman, here is a link http://en.wikipedia.org/wiki/Fibonacci_number

there is also the elliot wave theory, which uses the fibonacci sequencing. there are terms like retracements etc, that people can use to predict markets. I have not thought of it before, but it could be used to help see where oil price goes, or even nat gas. thereagain hindsight is 20/20 regarding how well it did or does. Fibonacci is very fascinating, and i am sure it is used in the markets trading. not just day traders.
