Super Fibo

Fibonacci retracement levels—stemming from the Fibonacci sequence—are horizontal lines that indicate where support and resistance are likely to occur.

Each level is associated with a percentage. The percentage is how much of a prior move the price has retraced. The Fibonacci retracement levels are 23.6%, 38.2%, 61.8%, and 78.6%. While not officially a Fibonacci ratio, 50% is also used.

The indicator is useful because it can be drawn between any two significant price points, such as a high and a low. The indicator will then create the levels between those two points.

Suppose the price of a stock rises $10 and then drops $2.36. In that case, it has retraced 23.6%, which is a Fibonacci number. Fibonacci numbers are found throughout nature. Therefore, many traders believe that these numbers also have relevance in financial markets.

Fibonacci retracement levels were named after Italian mathematician Leonardo Pisano Bigollo, who was famously known as Leonardo Fibonacci.  However, Fibonacci did not create the Fibonacci sequence. Instead, Fibonacci introduced these numbers to western Europe after learning about them from Indian merchants.1 Fibonacci retracement levels were formulated in ancient India between 450 and 200 BCE.
