Is it permissible to continue working exclusively on translating and reading news related to global financial markets and the trading of currencies, metals, oil, and gas, which does not include information about usurious stocks or prohibited products?

There appears to be no Sharia-based impediment to your work in transmitting, reading, and translating news, unless it involves endorsing something forbidden or promoting an evil. It is also permissible to publish data regarding interest rate forecasts, due to their impact on permissible transactions such as currency trading and investment, even though interest itself is from the forbidden usury of loans.
