The first two years of the NASCAR Chicago Street Race were accented by rain, but maybe the third edition will be a charm for fans and drivers.

Before the street race, there's the race behind the scenes to get the track, grandstands, cars, and other preparations ready for the main event.

India has barred one of the world's largest quant trading firms, Jane Street, from accessing its securities market after an investigation found it made "unlawful gains", taking the most stringent action ever against a foreign trading firm.

India has barred Jane Street from the country’s financial markets and said it would seize around $570 million that the U.S. securities firm made from allegedly fraudulent trades.

India’s stock market regulator has banned Jane Street from dealing securities in the country, accusing the New York-based trading firm of a “sinister scheme” to manipulate derivatives markets. The Securities and Exchange Board of India said its decision to limit Jane Street’s access to India’s securities markets stemmed from a months-long investigation.
