Fibonacci Retracement Levels Explained

Fibonacci retracement levels mark where price is likely to pull back before continuing a trend. The key levels are 23.6%, 38.2%, 50%, 61.8% and 78.6%. In Smart Money Concepts, the Optimal Trade Entry (OTE) zone sits between the 62% and 79% retracement — the highest-probability area to enter with the trend.
