IMO either up to the NYSE to provide a new clear tick indicator, your data provider, or given enough bandwith, computer power, some good ideas and the right software you can pretty much do it yourself. Also depends on how many symbols your data provider allows you to view simultaniously.

MetaServer has got a trial period btw and i am in no way affiliated with the company which sells it nor getting any money from them(unfortunately).
Maybe there's some other software which can do it, or it can be done inside TS.

If you think it's worth the effort, give it a shot.
