Fibonacci Retracements & Arcs
The Fibonacci sequence, named for its discoverer Leonardo Fibonacci, forms the basis for Elliott Wave theory used in trading financial markets. Out of Elliott Wave theory comes Fibonacci retrenchments and Fibonacci arcs discussed below. The Fibonacci sequence is 1,1,2,3,5,8,13,21,,34,55,89¦ to infinity. The sum of two consecutive numbers equals the next number. The ratio of any number to its next highest number approaches .618. The ratio of alternating numbers approaches .382. Also, 1 .618 = .382. The midpoint of .382 and .618 is .50. This is why .382, .50, and .618 are used. Retrenchments In technical analysis, Fibonacci retrenchments approximate support and resistance (and potential turning points) following a trend. Calculate the distance from the low to the high of the trend and calculate 38.2%, 50%, and 61.8% of the distance of the trend. Subtract those values from the top of the trend. Those are the potential reversal points. Charting packages perform the calculations for you all you have to do is connect the low of the trend with the high of the trend using the Fibonacci retrenchment tool. Arcs Following an uptrend, Fibonacci arcs use a line that connects the low and high of the trend but the line is drawn from high to low (not low to high as in retrenchments). Three curves that intersect the trend line (drawn from high to low) at the retrenchment levels of 38.2%, 50% and 61.8% are the Fibonacci arcs. The arcs are also estimations for support.
