Fibonacci Retracement

Indicators · Levels

Seven Fib levels between the rolling HH and LL.

Fibonacci Retracement draws the classic Fib levels across a price swing — the horizontal lines at 23.6%, 38.2%, 50%, 61.8%, and 78.6% between a high and a low — that traders worldwide watch for pullback support and resistance. The idea is that after a move, price tends to retrace a predictable fraction of it before continuing, and the 61.8% "golden ratio" level in particular is one of the most-watched prices in all of technical analysis.

How it works

Over the Lookback window (default 100) the block finds the rolling highest high (the 0% level) and lowest low (the 100% level), then plots the seven Fib levels between them: 23.6%, 38.2%, 50%, 61.8% (golden), 78.6%, plus the 0% and 100% extremes. Each is a line on the price pane, colour-grouped (extremes, mid levels, the 50%, and the golden 61.8% each get their own colour). As the rolling high/low updates, the levels recompute.

When to use it

Use Fibonacci Retracement to find pullback entry zones in a trend. The workflow: in an uptrend, wait for price to retrace into the 38.2%–61.8% zone (the "discount" area) and look for a bounce to rejoin the trend; the 61.8% golden level and the 50% are the most respected. It pairs beautifully with structure — a Fib level lining up with a Supply/Demand Zone or prior Swing is high-confluence. It's a location tool: it tells you where to look for entries, not when — combine with a trigger.

Example

Fibonacci Retracement on EURUSD · H1

A golden-ratio pullback: wire bars into Fibonacci Retracement, and in an uptrend look for price tapping the 61.8% level — combine that level touch with a bullish Crosses Above trigger through an And gate into a Buy Signal. Place the Fixed Stop-Loss below the 78.6% level and backtest in the Tester.

Tips & gotchas

• The 61.8% golden level and 50% are the most-watched — confluence there is strongest.
• Location, not timing — pair a level with a trigger for the entry.
• Confluence multiplies it — a Fib level on a Supply/Demand Zone or swing is far stronger.
• The 38.2–61.8% zone is the classic trend-pullback "discount" area.
