This is a valid question but in its current form it is incredibly broad. Perhaps narrow it down and if necessary post parts as separate questions.

@denesp on the other hand, I'm afraid narrowing down the question would involve a bias on the answers.

@denesp I believe some concievable changes may hapen to unexpected aspect of trading, and spliting may cause us to miss one or the other

all this has historical context and a colonial construct has been replicated by nations all over the globe, in fact, the whole thing about market closing especially in Asian exchanges before 4 pm, too, is of sorts a colonial or more like a commonwealth thing. Nevertheless, it is an objective decision. Have found one podcast that is global as well as Indian stock market-centric, which has explained everything about this in detail, yet in under 15 minutes.

# What would happen if stock markets were open 24 hours?

(Asked by: username_0 on 2015-09-10)

Suppose you are a broker or a trader, and the stock markets will be open 24 hours a day.

What would be the implication for you as a broker in this scenario?
I mean:

* How will your strategies change?
* Will it be more difficult or easier to trade?
* What algorithms that you know that would have to be adjusted in this scenario?

You would have trading teams who work shifts like any other 24-hour business areas.

The power market is open 24-7; many companies have around-the-clock trading teams. A lot of analysis and other work that can be done in the daytime is still done in the daytime.

A major source of income during nighttime - in the power market - is just being there and executing trades - when other people are not there. I think that is the main change, that liquidity would shrink and give more arbitrage opportunities.
