Dynamic DOM re-centres each tick on last price. Static stays centred until you hit a centre button. The latter is far superior other wise you are clicking a moving target to enter trades. Unworkable in my opinion. TT claim to have some sort of patent on the latter though I always thought it was complete hogwash. A search should reveal some of their outrageous demands and assertions.

I believe someone has finally challenged the patent in court. Hoorah.

cheers.
