"With the increased integration of the global markets, information originating from different countries has a bearing on Indian securities market," said the Securities and Exchange Board of India (SEBI) in a statement.

While trading on the Asian bourses commences little ahead of the Indian markets, the European and American markets open much later, SEBI said asking various stakeholders for their views on determining optimum market timing, before April 10.

"Some of the exchanges in these countries have adopted longer trading hours, sometimes even extending up to 23 hours. This has facilitated market participants in these countries to hedge their risk that might arise due to global information flow," SEBI said.

Among the advantages noted by the regulator are incorporating information flowing from different time zones, markets becoming efficient with quick assimilation of data, attracting global trading interest and enabling participants to take longer positions.
