ARIA Live and values that updates very quickly

Dear All,

A client has a page that presents Buy and Sell values for certain currency
or investment transactions. Not surprisingly these values are dynamic and
so an ARIA live region would seem to be the obvious choice.

However, I'm told that the values can be updated up to 5 times per second.

Even if we used aria-live="polite" I still think there would be a lot of
verbiage. The last thing we'd want to create is an endless commentary since
there are other things on the page a site visitor might wish to interact
with and read.

Has anyone got any suggestions as to how we could address this? Are there
ways of dynamically switching on and off an aria-live region - with
javascript say? Does that work with screen readers?

Once again, thanks in advance.
