How to use it

  1. Pick the last clear swing on your chart: in an uptrend from the swing low to the swing high, in a downtrend from the high to the low.
  2. Enter both prices. The table shows where a pullback may react (retracements) and where the move may run next (extensions).
  3. Press Copy levels and paste them into your notes or alerts.

The formulas

Uptrend: retracement = high − (high − low) × ratio; extension = low + (high − low) × ratio. Downtrend: the mirror. Example on gold: low 4,000, high 4,100, range 100. The 61.8 % retracement is 4,100 − 61.8 = 4,038.20, the 70.5 % OTE level is 4,029.50 and the 161.8 % extension is 4,000 + 161.8 = 4,161.80.

Fibonacci in ICT trading

ICT traders look for entries between 62 % and 79 % of a swing (the optimal trade entry), in the discount half for buys, ideally where a fair value gap or order block sits. A level alone is not a signal: wait for a reaction, and size the trade with the lot size calculator. Daily levels: pivot point calculator.

Questions

What are the main Fibonacci retracement levels?

23.6 %, 38.2 %, 50 %, 61.8 % and 78.6 %. 50 % is not a Fibonacci ratio but is widely watched as the middle of the range. ICT adds 70.5 % as the optimal trade entry.

Which swing should I measure?

The most recent clear swing on your trading time frame: from the low to the high for an uptrend, from the high to the low for a downtrend.

What are Fibonacci extensions used for?

Targets: 127.2 %, 161.8 % and 261.8 % show where a move may run after it breaks the swing high (or low).
