Former commodity trader Martin Armstrong’s two-decade legal battle with federal regulators appeared to be coming to a close in 2017.

The self-taught economic forecaster (whose computer model was built on the number pi) was incarcerated for 11 years over financial fraud and contempt of court. He was allowed to review the contents of storage lockers in New Jersey and Pennsylvania for personal items the government has been holding on to since it first began seizing items from Armstrong’s home and office in 1999.
