sometimes markets close for brief periods of time, if happened quick you wouldn’t have time to let people know. I think the “trading suspended” message is possibly the best option to give and resort back to here to ask, why?
Yes, if there are no new quotes (trades being placed) then the instrument will automatically get closed until new quotes are added and then it will resume
If by quotes you mean buy\sell orders, the price increased, and I then tried to sell, the price decreases and I tried to sell, and it decreased again. All of this happened within 5 minutes.
With regards to trading212, displaying a notification of the trading status. The system already has the functionality of this to extent.
If conditions equals true, then do something.
If no quotes within xyz time range, then disable trading.
This could be, if no quotes within xyz time range, then disable trading and set “market open” to “Market Open - (TS)”.
As for latency testing, a basic ping test would determine this, and I’m only using ping test, to get the idea across, and depending on the results Red, Amber or Green could be displayed as a notification next to “Market Open” but maybe trading212 wouldn’t want customers seeing this as this should be fixed behind the scenes to ensure this doesn’t happen (some kind of failover procedure to another server\network or what ever the case maybe).
Just my 2 pence
But when referring to quotes what exactly are you referring to? A trading platform should allow you to trade???
This denotes the prevailing buy and sell prices for a particular financial instrument. Quotes are displayed as: sell price – buy price. For example, if 125.7 – 125.9 is the quote: 125.7 is the sell price and 125.9 is the buy price.
