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/dxy-dollar-index-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 US Dollar Index (DXY) Calculator
The dollar index is quoted in every forex market report, yet few readers know that more than half of it is the euro. The widget calculates DXY from its six rates and splits any move by currency.
What the widget calculates
A DXY calculator applies ICE’s formula to EUR/USD, USD/JPY, GBP/USD, USD/CAD, USD/SEK and USD/CHF to produce the US Dollar Index.
Readers enter the six rates and their changes and see the index, its change in points and percent, and how much each currency contributed.
The embedded version keeps the inputs and the result. The full US Dollar Index (DXY) Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.
