India’s securities regulator plans to boost its surveillance systems to better detect complex trading strategies after taking action against high-speed trading giant Jane Street Group for alleged market manipulation.

India's market regulator said it had barred U.S. trading company Jane Street from accessing the local securities market, after an investigation into alleged market manipulation through positions taken in equities derivatives.

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.
