Calculate key Fibonacci levels for your trading analysis — including ICT's Optimal Trade Entry (OTE) zones
Enter your swing high and low prices, then click "Calculate Levels" to see Fibonacci retracement and extension levels.
Fibonacci levels are horizontal lines derived from the Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, 21...). In trading, the ratios between consecutive Fibonacci numbers (23.6%, 38.2%, 50%, 61.8%, 78.6%) are used to identify potential support and resistance zones where price may reverse.
The 61.8% level, also known as the Golden Ratio or Phi, is the most powerful Fibonacci retracement level. It appears throughout nature and mathematics. In trading, price respects this level more consistently than other Fibonacci ratios. Many traders consider a retracement to the 61.8% level as a strong confirmation of trend continuation.
Inner Circle Trader (ICT) methodology defines the Optimal Trade Entry zone as the 62%-79% retracement range (highlighted in this calculator). This zone offers:
Combine Fibonacci levels with order blocks for maximum trading precision. When price retraces to a Fibonacci level AND creates an order block at that level, you have a high-probability reversal setup. The OTE zone (62%-79%) is especially powerful when it coincides with an order block on a lower timeframe.
Retracements: Price pulls back within the original move (0%-100% of the swing). Extensions: Price breaks beyond the original high/low and continues (-127.2%, -161.8%, -200%, etc.). Extensions help identify potential profit-taking levels.
1. Identify a significant swing high and swing low on your chart. 2. Enter both prices. 3. Select the trend direction (uptrend = from low to high, downtrend = from high to low). 4. View retracement and extension levels. 5. Look for confluence with other support/resistance areas and order blocks.
