Constructing Fibonacci retracement, projection, and range maps

Start from one swing

Fibonacci lines are constructed as retracements, extensions, and projections from a chosen high-low swing. The same geometry can then mark likely pause zones and later price targets.

The first construction choice is that swing. It sets the chart 0-100 scale that later retracement and projection lines will share.

Retracement inside the swing

A retracement construction places 61.8%, 50%, and 38.2% between the nearest high at 100% and the nearest low at 0%. Those interior levels locate areas where price may stop and resume the prior trend.

Projection beyond the swing

Levels drawn beyond 100% of that same swing are treated as extensions or projections. They identify likely continuation targets rather than pullback support.

One illustrated daily construction retraces a recent high-low swing to 50% and then projects the 127.2% and 161.9% levels as the next measured objectives.

Support and resistance maps

Horizontal lines are constructed across prior reaction points to mark support and resistance. The map can include recent and older levels, and the same lines also complete patterns such as triangles and rectangles.

Round-number levels are treated as effective horizontal construction points when mapping breakout reference prices.

Once a trading-range high and low are identified as resistance and support, the same measured height can be projected above or below the range after a breakout. That measured move forms an upside or downside target.

A hand-drawn hypothesis

Drawing tools are applied by hand on the chart rather than as purely automatic formulas. Fibonacci retracement, Fibonacci projection, and support and resistance constructions therefore remain discretionary even when the ratios themselves are fixed.

The same constructions are meant to work with other technical or fundamental confirmation. A mapped level then becomes a hypothesis about where price is likely to pause or travel after a trend is confirmed.
