| - | ===== Introduction ===== | + | ===== What are Fibonacci Arcs? ===== |
| - | Fibonacci Arcs are half circles that extend out from a trend line. The first and third arcs are based on the Fibonacci ratios .382 (38.2%) and .618 (61.8%), respectively, which are often rounded to 38% and 62%. The middle arc is set at .50 or 50%. After an advance, Fibonacci Arcs are measured using a **Base Line** that extends from trough to peak. Arcs are drawn along this line with radii that measure .382, .50 and .618 of the Base Line. These arcs mark potential support or reversal zones to watch as prices pull back after the advance. After a decline, Fibonacci Arcs are used to anticipate resistance or reversal zones for the counter-trend bounce. This article will explain the Fibonacci ratios and provide examples using Fibonacci Arcs to project support and resistance. | + | Fibonacci Arcs are versatile tools that help identify support and resistance levels in a changing market. It does this by incorporating a time component, which gives you a more comprehensive and adaptable view of price barriers. |

| The first step is to pick the peak and trough for the Base Line. Draw the line from trough to peak for an advance or from peak to trough for a decline. The example above shows Home Depot with a Base Line from trough to peak. The radius for the first Fibonacci Arc measures 38.2% of the Base Line. The radius for the second Fibonacci Arc is in the middle of the Base Line (50%). The radius for the third Fibonacci Arc measures 61.8% of the Base Line. Three half circles are drawn based on these radii. Notice how HD reversed near the third Fibonacci Arc (61.8%). | The first step is to pick the peak and trough for the Base Line.

| - | ===== Interpretation ===== | + | ===== How Do You Interpret Fibonacci Arcs? ===== |
| - | Fibonacci Arcs add a time element to Fibonacci retracements. The Fibonacci Retracements Tool is based on a vertical line from trough to peak or from peak to trough. It is only concerned with the change in price. In contrast, a Base Line after an advance extends from trough to peak at an angle that is dependent on elapsed time (positive slope). A Base Line after a decline extends from peak to trough at an angle that is also dependent on elapsed time (negative slope). The slope and length of the line depend on changes in both price and time. A big price movement over a long period of time produces a long Base Line with wide arcs. Conversely, a small price change over a short period of time produces a short Base Line with narrow arcs. | + | Fibonacci Arcs add a time element to Fibonacci retracements.

| - | Chart 2 shows Home Depot with the Fibonacci Retracements Tool and the Fibonacci Arcs. Both indicators extend from the July low to the September high. Notice how the Base Line slopes up and is longer than the vertical line in the Fibonacci Retracements Tool. Whereas the Fibonacci Retracements Tool shows static retracement levels, the Fibonacci Arcs show dynamic retracements that evolve over time. Fibonacci Arcs drawn after a decline slowly work their way lower, which denotes falling resistance zones. Fibonacci Arcs drawn after an advance slowly work their way higher, which denotes rising support zones. Despite these differences, both tools are used to anticipate support, resistance and reversals. | + | Chart 2 shows Home Depot with the Fibonacci Retracements Tool and the Fibonacci Arcs.

| - | ===== Conclusion ===== | + | ===== The Bottom Line ===== |
| - | Fibonacci Arcs are used to identify potential support, resistance or reversal points. As with the Fibonacci Retracements Tool, these reversal points assume that the move is corrective in nature. A pullback after an advance is deemed a correction that will find support above the beginning of the advance. A bounce after a decline is deemed a counter-trend rally that will hit resistance below the beginning of the decline. Fibonacci Arcs allow users to anticipate the ending points for these counter-trend moves. Like all annotation tools, Fibonacci Arcs are not meant as a standalone system. **Just because prices approach an arc does not mean they will reverse.** Prices move right through these arcs in many cases. **No indicator is perfect.** This is why chartists must use other tools to confirm support, resistance, bullish reversals and bearish reversals. | + | Fibonacci Arcs are used to identify potential support, resistance or reversal points.

| + | ===== Fibonacci Arcs FAQs ===== | ||
| + | ==== How do Fibonacci Arcs differ from the Fibonacci Retracements? ==== | ||
| + | While Fibonacci Retracements focus solely on price changes, Fibonacci Arcs incorporate a time element. Arcs are based on an angled Base Line, considering price and time changes. | ||
| + | |||
| + | ==== How can you use Fibonacci Arcs for support? ==== | ||
| + | After an upward movement, consider where prices may find support as they pull back. If prices reverse near an arc, it could indicate a potential support zone. | ||
| - | {{:chart_analysis:fibonacci_arcs:farc-9-shch.png|Chart 8 - Fibonacci Arcs}} | + | ==== How can you use Fibonacci Arcs for resistance? ==== |
| + | After a decline, Fibonacci Arcs can help anticipate potential resistance zones for a bounce in prices. A halt or reversal of the bounce near an arc might indicate resistance. | ||

| + | Yes, to see future potential support or resistance levels, chartists can add extra bars or periods to their charts, thus extending the "dateline." | ||
| + | ==== Are Fibonacci Arcs a standalone trading system? ==== | ||
| + | No, while Fibonacci Arcs provide valuable insights, they should be used with other tools to confirm support, resistance, and potential reversals. | ||
