"This issue will take a while," SEBI Chairman C B Bhave told PTI while giving details of how the issue is being discussed at a high level committee of the regulator.
There has been demand for extending the trading hours beyond 0955 hours to 1535 hours as part of efforts to align business with the markets in Asian region to guard against the lagged effect on Indian scrips.
"Actually this issue (extending market hours) got discussed in our secondary market advisory committee but there the participants pointed out that there are lot of practical nitty-gritty that needs to be sorted out before the decision is taken," he said.
Citing some of the issues, he said, "If you are having trading between 5 in the evening till 11 at night then how do people do the banking transactions during that time. If somebody has to bring in additional margin where is the mechanism to bring that."
The second, Bhave said, "If you close the trading window at 11 o'clock at night then you would be still be doing T+2 (Trading plus 2 trading session) or would be declaring this session as part of the next day session.
