The swing

A clear swing you chose before looking at the lines.
To see how deep the pullback is.

The lines

An example with typical numbers. Change any box to use your own.

The pullback is 40.0% of the move: 4,040.00 sits between the 38.2% line at 4,042.70 and the 50% line at 4,025.00 (marked in the table).

Retracement lines of the move up from 3,950.00 to 4,100.00 (150.00 long).

Extension lines past the swing high: where the next leg would end at that multiple of the first.

Size a buy here with the stop at the 50% line (4,025.00). A stop just past a line can still sit inside normal movement: check the stop noise.

The 50% line is not a Fibonacci ratio; most platforms draw it anyway. Two traders who pick different swings get different lines.

Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

A rough map, not a rule

Fibonacci lines are fractions of a move. Many traders watch the same ones, so a pullback sometimes pauses near them, and often runs straight through. Their weak point is the swing: choose it before you look at what price did near the lines, and keep it, or the lines end up fitted to the past. How to draw them and what they can and cannot do: Fibonacci retracement on gold.

Not advice. The lines are arithmetic on the numbers you type, not a view on any market.
