Wonderful, here I am in the middle of an index warrant trade and NAB's quote screen has gone down the toilet. All quote/depth requests are just returning "blahblah is not a valid code. Please try again"
This happens a bit when things are busy, but it's been down for the last 10 minutes or so now. Just as well I can see the index movement on the ASX website, and it's currently moving in the right direction!
No idea if the order system is still working or not, but how can I use it anyway when I can't even get a basic quote let alone market depth.
