I translated 3 websites (10-23,000 words each) and also parts/updates of other websites. A big part of these websites are explaining how to trade, what terms are used (MACD, anyone?), and manuals on either webbased programs or mobile apps to trade.
During 5 years, I translated weekly and daily (sometimes twice daily) newsletters with updates on the financial markets. Eventhough the client stopped these newsletters for the Dutch market, of course I still keep up-to-date with financial news.
Facebook banners, Google Ads, all kinds of texts for landing pages, for various clients in this field.
I translated a few apps (partly).
