Three practical forex widgets for your own website
Add a position-size estimator, a reward-to-risk helper and a drawdown-recovery calculator to any ordinary HTML site. The package is dependency-free, responsive and performs all calculations in the visitor’s browser.

Useful calculations—not decorative tickers
Position size
Uses account balance, chosen risk percentage, stop distance and pip value per standard lot to estimate trade size.
Reward-to-risk
Compares target with stop distance and adds an optional expectancy estimate expressed in R.
Drawdown recovery
Shows the asymmetric percentage gain required to recover from a selected account drawdown.
Embed one or all three
Upload the included CSS and JavaScript files, then add the widget container where the calculator should appear.
<link rel="stylesheet" href="/assets/trade-forex-widgets.css">
<div data-tf-widget="position-size"></div>
<script src="/assets/trade-forex-widgets.js" defer></script>Change the data attribute to reward-risk or drawdown-recovery for the other tools. The included example.html demonstrates all three together.
Implementation details
No dependencies: plain HTML, CSS and JavaScript with no framework or build process.
Responsive: the controls adapt to narrow columns and mobile screens.
Privacy-friendly: values stay in the browser; nothing is sent to Trade-Forex.info.
Accessible output: results use an ARIA live region and update as inputs change.
What to tell your visitors
- State the account currency and assumptions used in the input values.
- Explain that pip value varies by pair, account currency and position size.
- Do not present calculator output as personalised advice or a profit forecast.
- Keep the source link visible so visitors can find the methodology and larger calculator suite.
