How to Use Fibonacci Levels in Trading
Fibonacci retracement levels mark where price may find support or resistance during a pullback. The most commonly watched levels are 38.2%, 50%, and 61.8% — often called the “golden zone.”
Extension levels (127.2%, 161.8%, 200%) project where price may move after completing a retracement, making them ideal for setting take-profit targets.
Combine Fibonacci levels with GrandAlgo's smart money indicators to confirm entries at key retracement zones. Our Session Fib Fan indicator automatically plots these levels on your TradingView charts.
