Frequently Asked Questions
How do I use a Fibonacci retracement calculator?
Enter the swing high and swing low prices of a recent price move. The calculator will automatically compute key retracement levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) where price may find support or resistance during a pullback.
What is the 61.8% Fibonacci level?
The 61.8% level is known as the 'Golden Ratio' and is considered the most important Fibonacci level. It's derived from the Fibonacci sequence where each number divided by the next approaches 0.618. Many traders consider this the ideal retracement level for trend continuation.
How do I identify swing high and swing low?
A swing high is a peak with lower highs on both sides. A swing low is a trough with higher lows on both sides. For uptrends, use the most recent swing low and swing high. For downtrends, reverse the order.
Should I use Fibonacci for entries or exits?
Both! Use retracement levels to find entry points during pullbacks, and use extension levels to set profit targets. The 61.8% retracement is popular for entries, while 161.8% extension is common for targets.
Do Fibonacci levels work for crypto and stocks?
Yes, Fibonacci levels work across all markets including stocks, forex, crypto, and commodities. They're based on mathematical relationships that reflect natural patterns in price movements driven by human psychology.
