Value Area

Can somebody please explain what "Value Area" is and how to trade this area.

Thanks for that, why I ask, I was in Larry levin room secrettraders and they use the VA but they base theirs on Volume....He seem to think the floor looks at VA but based on the Voulme one....I don think theres much between the two though

The Market Profile TPO structure was created to proxy volume back in the days when volume data was difficult to come by and difficult to chart in this manner. Theoretically a volume profile should be superior but if more traders are using a Market Profile then that could swing the balance.
