How to add it to your site
- Copy the code Use the copy button in the Embed code box so nothing is lost to line wrapping. It is a single iframe tag and it does not need anything else.
- Open the page you want it on In WordPress add a Custom HTML block, in Wix use the Embed HTML element, in Squarespace use a Code block, and on a hand-built site paste it straight into your HTML.
- Paste and publish The widget appears immediately. If you see an empty space instead, your editor has stripped the iframe tag, which the HTML embed guide explains how to work around.
- Adjust the look if you want to Add the parameters in the table below to the iframe URL to change the theme, the accent colour or the height. Nothing needs to be configured on our side.
Customisation options
| Parameter | Values | What it does |
|---|---|---|
theme | auto, light, dark | Default follows the reader's own system setting, so the widget looks right on a dark site and a light one without you choosing. |
accent | Six hex digits, e.g. accent=1A56DB | Recolours the header bar and the primary button to match your brand. |
header | 1 or 0 | Set to 0 to hide the title bar when your page already has a heading above the widget. |
breakdown | 1 or 0 | Set to 0 to hide the calculation breakdown for a more compact block. |
corners | 1 or 0 | Set to 0 for square corners if your design has no rounding anywhere else. |
width | full | Removes the 520px maximum so the widget stretches to its container. |
Parameters are added to the iframe URL as a normal query string, for example
/embed/fibonacci-retracement-calculator.html?theme=dark&accent=1A56DB&header=0. The
widget builder lets you set all of them visually and hands you the finished code.
Why embed the Fibonacci Retracement Calculator
Fibonacci levels are drawn on charts constantly and calculated by hand almost never. This widget takes a swing high and low and returns the standard retracement levels for both an uptrend and a downtrend. Technical analysis blogs and trading education pages can show readers the levels are arithmetic on two prices.
What the widget calculates
A Fibonacci retracement calculator works out the key retracement and extension price levels for a given price swing, based on the standard Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%) that traders commonly watch for potential support and resistance during a pullback.
Enter the swing high and swing low of the move you're analysing, select the trend direction, and the calculator produces the exact price at each retracement level, along with two common extension levels for projecting targets beyond the original swing.
The embedded version keeps the inputs and the result. The full Fibonacci Retracement Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.
