Retracement
A Retracement is a temporary, partial reversal of a security's price movement within an established primary trend — typically characterized as a percentage pullback of a prior advance (in an uptrend) or a partial recovery from a prior decline (in a downtrend) — used by technical analysts to identify potential support or resistance zones where the primary trend is likely to resume. Fibonacci retracement levels (23.6%, 38.2%, 50%, 61.8%, and 78.6% of the prior move) are the most widely used reference points for anticipating where a retracement may find support or resistance.
Key takeaways
- A retracement differs from a reversal in that it is a temporary counter-trend move that eventually resolves back in the direction of the primary trend.
- Fibonacci retracement levels derive from the Golden Ratio (1.618) and its reciprocal; market technicians find these levels empirically useful as potential turning points, though their predictive power is debated.
- The 38.2% retracement of a prior move is considered a 'shallow' retracement consistent with a strong trend; the 61.8% level is a 'deep' retracement that tests the trend's integrity.
- Volume should decline during a retracement, suggesting that the counter-trend move lacks conviction and the primary trend is likely to reassert; heavy volume on the retracement may signal a more serious reversal.
- Candlestick reversal patterns (hammer, engulfing, doji) at Fibonacci retracement levels provide confirmation signals that the retracement may be ending and the primary trend resuming.
Explanation
Retracement analysis is one of the most widely applied tools in technical analysis, used by traders and analysts across asset classes to identify entry points in established trends, set stop-loss levels, and assess the health of ongoing moves. The underlying logic is simple: after a significant advance or decline, profit-taking, position adjustment, and counter-trend trading by short-term participants cause prices to pull back from their extremes, testing the conviction of trend participants before the primary trend reasserts.
Fibonacci retracement levels are the dominant framework for identifying specific price zones within a retracement. The levels — 23.6%, 38.2%, 50%, 61.8%, and 78.6% — are derived from the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21...) and the golden ratio (1.618...), which appears in geometry, biology, and human perception of proportion. In financial markets, the 38.2% and 61.8% levels are most closely watched, with 61.8% (the 'golden ratio' retracement) considered the deepest retracement that an intact uptrend should sustain before resuming. A pullback that penetrates the 61.8% level and continues to 78.6% or beyond raises the probability of a complete trend reversal rather than a healthy retracement.
The Average True Range (ATR) provides a complementary perspective on retracement analysis. By measuring the typical daily range of a security (accounting for gaps), ATR gives context to whether a retracement's magnitude is within normal volatility bounds or represents an unusual move. A stock that typically moves $2 per day (ATR = $2) and retraces $6 over three days is displaying a two-standard-deviation move — potentially more than a routine retracement. Bollinger Bands similarly provide dynamic support and resistance bands that adapt to current volatility, offering a probabilistic framework for evaluating whether a retracement has extended into an unusual range.
For trend-following hedge funds and systematic CTAs, retracement analysis informs position management rules. A common approach uses the retracement depth relative to the prior move to adjust position sizing: at a 38.2% retracement with bullish candlestick confirmation, the fund adds to its long position; at 61.8% retracement without confirmation, it maintains but does not add; below 61.8% without recovery, it begins reducing the position. This systematic use of retracement levels creates a disciplined risk management framework that avoids arbitrary position decisions while remaining responsive to price action.
Formula
Fibonacci Retracement Level = Trend High - (Trend Range × Fibonacci Ratio)
Example
The EUR/USD currency pair rallies from 1.0500 to 1.1200 over six months — a move of 700 pips. A pullback begins as the pair approaches 1.1200, a prior resistance level. Technical analysts calculate the key Fibonacci retracement levels: 23.6% retracement = 1.1200 − (700 × 0.236) = 1.1035; 38.2% retracement = 1.1200 − (700 × 0.382) = 1.0932; 61.8% retracement = 1.1200 − (700 × 0.618) = 1.0767. The pair pulls back to 1.0935 — just below the 38.2% level — and forms a hammer candlestick on declining volume. A trend-following trader treats this as a high-probability retracement continuation setup, entering long at 1.0960 with a stop at 1.0720 (below the 61.8% level). The target is a resumption of the primary uptrend toward 1.1500. The 38.2% Fibonacci level provided the expected support, consistent with its role as a key retracement reference in a strongly trending market.
