It seems like this change to trading 24 hrs. a day is coming later in this year.
I am finding it difficult to imagine how I would trade anything.
How come nobody has initiated any discussion on this coming change?
 
Hmmm... Back in 2000, I read of plans of the exchanges to have 24/7 trading. I did not follow the development, but obviously, it did not happen. I wonder if the dot-com/tech stock crash had anything to do with it.

Just now, researched the Web, and found out that they talked about it back in 1999. In fact, some were proposing it back in 1991. How many people even had an Internet connection in 1991? Amazing.
 
While not a tec person, I went to collage in 1991, it was basicly only news articals you could get over the internet that were allready in print in magazines. So a periodical database.
 
Market closure overnight acts as a sort of circuit breaker. I wonder if non-stop trading will lead to more volatility.

Netscape Web browser was released in 1994. In 1991, early Web search engines such as Webcrawler, Lycos, AltaVista, Northern Light also did not exist. People mostly used dial-up modem to log onto AOL forums.

I have never used pre-market and after-hours trading. I don't think the volume there is very high. I wonder if there's a real interest in 24-hour trading.

Will they treat mutual funds like ETFs and allow trading at any time?
There's currently no mechanism for mutual fund share holders to trade shares between themselves; the transactions are always settled through the mutual fund companies. If a mutual fund is restructured to be traded like an ETF, then it becomes an ETF and is no longer a mutual fund.
 
In the past, I've noticed stock prices sometimes radically changes during non-business hours.

This isn’t new. 24-hour trading already exists though not 100% implemented. But it’s been a thing for a while. I’m not a trader so it doesn’t affect me though.
 
I saw an interview with the head of the Nasdaq exchange last week, I think. She said it's only the Nasdaq exchange that will be open 24hrs so far. And, that will only be that way on weekdays. I believe she said the planned start date is 12 midnight, New Years eve 2026. That's about all I remember on it.

I would think not. Funds have always had the luxury of being the only thing on the system during the nightly process.

I'm concerned about the ability for maintenance and do the required backups. While the vendors have been working on save while active strategies there were windows of opportunity that could have missed backing up certain rows that were currently locked.

There's certain maintenance tasks that can't be done with activity on a system. I remember a very large provider who decided to do a maintenance task over a three-day weekend. It took four days to complete. They were not happy.

I guess because I don't plan to take the opportunity to trade 24 hours.

Yes, but the newspaper reporters and the collage news office I was at had acess to periodicals. So I cant remember if they had a browser, but yes it was dial up. We didnt have acess to AOL, at least not in school. I forgot, if you called the number of the place that had the information, or if you put that into the computer after you went on line. If could be you just dialed into one of the libraries. It was a long time ago.
 
I suspect this growth is a result of stockmarket ownership consolidation. Worldwide ETF's will likely trade during optimum liquidity time slots by convention. Lumpy at first and then patterns of activity will emerge.

That’s what I remember, 1999 2000. Didn’t happen.

in today's cloud world, this is no longer a thing.
blue/green and replicated systems real time. patching is done on the cold instance, a switch is flipped, all traffic goes there, over time the hot one becomes cold. patching is done again.
 
Traded some Microsoft this morning "pre-market" just to try it out at Schwab. I noticed MSFT took a big jump about 30 minutes before the market opened so I said why not give this pre-market "thing" a try. Put a sell order in of 100 shares with a limit of 430. It closed yesterday around 420 (IIRC) Sold within a few minutes. Missed the top of 433 pre-market but that's okay, its back down to ~418 now during regular trading.

Worked just like the regular session except you just check the box for extended hours trading. Not a bad deal if you like swing trading.

The first "world wide web" web site happened in 1991. The first public use was 1993. I was working on some Unix stuff and we started playing with it around then.

Thinking bact to it, it may have been just phoning over the modem to a library data base. I remember having a number to call. I think anyway. Was a while ago. We had acess only from the journalism computers to check facts and articals. It wasn't like the internet now. We linked in and they typed stuff in a bar and it gave a list of documents to choose from. So it was internet, but probably not like it is now.
 
Well the traditional stock exchanges are facing intense competition from two sides. The crypto market never sleeps and retail brokers offer 24/5.
The institutional world is quiet because they are terrified of the operational nightmare.
