Oh and, if the price is at 110 euro, and i sell 400 BTC right away, howmuch will the price drop? Or is it relevant.

And another question: on the BITCOINITY.ORG char you see updates in the format -X.XX -X minutes ago - BTC PRICE - Green/Red arrow (up/down)

The first cypher (for example 4.02) with a green arrow. Does that mean that 4.02 btc got bought? And for example 1.72 with a red down arrow, does that mean 1.72 btc got sold, with the matching 'new market price' before the arrow?

In other words, if i sell 400btc on Gox, then will it appear on there in the format "400.00 1 minute ago 100.00 *red arrow down* meaning that my sell-off brought the price down to 100.00 euro? So then i know howmuch my sell-off brought down the price .. ?
