Fibonacci Retracement Calculator

The core of Fibonacci analysis relies on the relationship between numbers in the Fibonacci sequence. The calculation begins by determining the total price range, or the difference between a swing high and a swing low. For an uptrend, the price differential is calculated as Rise/Fall = High - Low. Once the range is established, standard Fibonacci percentages—such as 23.6%, 38.2%, 50%, 61.8%, and 76.4%—are subtracted from the high to determine retracement support levels (Ur levels). Conversely, Fibonacci extensions (Ue and De levels) project where a trend might continue or exhaust itself by multiplying the price range by ratios like 1.618 and 2.618 and adding or subtracting them from the baseline prices.

Consider an asset experiencing a strong bullish wave with a recorded swing low of $50 and a swing high of $100. First, we compute the total price range: Rise/Fall = $100 - $50 = $50. Next, we determine the 50% retracement level by multiplying the range by 0.5 and subtracting it from the high price: Ur_3 = $100 - ($50 * 0.5) = $75. Similarly, to find the 61.8% retracement level, we calculate Ur_4 = $100 - ($50 * 0.618) = $69.10. Traders monitoring this asset would watch these specific price zones ($75.00 and $69.10) for signs of a bullish bounce before the primary uptrend resumes.

Always apply Fibonacci tools to major swing highs and lows on higher timeframe charts, such as the daily or weekly, for more reliable signals. Avoid relying on Fibonacci levels in isolation; instead, combine them with volume indicators, moving averages, or candlestick patterns for confluence. Keep in mind that markets do not always reverse precisely at a Fibonacci ratio, so utilizing proper risk management and stop-loss orders is paramount.
