Fibonacci retracement
A tool that draws levels at 38.2%, 50% and 61.8% of a move between a swing low and a swing high. They show where a pullback may stop.
What it is
The Fibonacci retracement tool splits a clear price move into parts. The most used levels are 38.2%, 50% and 61.8%, less often 23.6% and 78.6%. Most come from ratios in the Fibonacci sequence. The 50% level is not a Fibonacci ratio; traders use it out of habit. The levels are not magic: they help you mark in advance the zones where a pullback often slows down.
How to draw it
- Find a clear move: an obvious swing low and an obvious swing high on the same timeframe.
- In a rising move drag the tool from the low to the high, in a falling move the other way round.
- In a rising move each level is the high minus the size of the move multiplied by 0.382, 0.5 or 0.618. In a falling move the same amount is added to the low.
- Read the levels as zones, not exact lines, and check whether they line up with support or resistance.
Real example: BTC in 2024 and 2025
On the weekly chart BTC/USDT rose from 49,000 (week of 5 August 2024) to 109,588 (week of 20 January 2025). The move was 60,588, so the 38.2% level sits at 86,443, 50% at 79,294 and 61.8% at 72,145. From late February to early April 2025, weekly candles dipped into the zone between 50% and 61.8% four times and stopped there. The lowest point, 74,508, was a retracement of about 57.9%. Price did not stop exactly on a line, so the levels work better as zones. This case does not prove the levels always work: in another move price can slice straight through.
Common mistakes
- Picking points so the levels "fit". The low and the high must be obvious, not chosen to match the answer you want.
- Drawing levels on small, noisy moves. The smaller the move, the less its levels mean.
- Treating 61.8% as guaranteed support. If price closes well below it, the structure of the move has already changed.
- Using Fibonacci on its own. The levels carry more weight when they line up with an earlier level or another tool, which is called confluence.
How to practise
On a daily or weekly chart, find ten clear moves and draw the levels on each. Note where the pullback stopped: before 38.2%, between 38.2% and 61.8%, or deeper. After ten cases you will see how the results scatter and why the levels are used together with support and resistance levels.
