GoExchange

GoExchange is a Chrome extension that applies machine learning to currency forecasting. Instead of stopping at the live spot rate like a standard converter, it produces estimates of where the Euro is heading against other currencies, using real-time data published by the European Central Bank as its input.

The extension retrains on updated ECB data daily, which matters for a forecasting model: stale training data is one of the quickest ways for rate predictions to drift out of relevance. Coverage is currently focused on Euro-to-major-currency pairs — the listing names the US Dollar, Japanese Yen, Pound Sterling and Turkish Lira — with a fuller list available through the developer.

It is published by the owner of conversion.onesaas.de and is a compact install (about 40 KB), so it sits quietly in the browser rather than running as a full trading dashboard. The listing shows a 5.0 rating from a single review and a small user base, so it is best treated as a lightweight personal forecasting aid rather than an institutional-grade FX system.
