Navinder Singh Sarao, the British trader accused of contributing to the 2010 stock-market “flash crash,” won’t serve any more time in jail, a federal judge ruled Tuesday, capping a multiyear saga that gripped markets and traders after one of the most dramatic stock plunges in history.

Sarao was sentenced to time served as well as a year of home confinement by Judge Virginia Kendall of the US District Court for the Northern District of Illinois. He will be allowed to leave his house for medical appointments, work and church, among other preapproved reasons.
