From the above list, I see, many Europian exchanges running much longer hour like 8-4:30 or 9-5:30 without a lunch break =>
8 HR 30 MIN. We Indians are hard working; if Europeans can do why we can't?
So there is further scope to increase the time up to at least 5:30 PM.
It is possible to extend up to 6:30 with 1 hr lunch break. Or up to 7:30 with start time @10am and 1 hr lunch break.
I like the market time for
BRAZIL, It's 10AM to 5:30PM. I m missing old 10 AM times. Extra 1hr before everyday exam is always good for preparation/planning
& also good for 10 am lunch/heavy breakfast if there is no lunch break.
3:30 PM is too much early to finish a job for a country like India where Average Sun Set time is 6 PM+.
We are not that much lazy, still lots of energy left after market close @3:30PM. IMO.
And trading Currency or MCX is not a replacement of trading Stock Market for most of the traders.
