number of buy orders, market participants may believe a price drop is imminent and trade accordingly.
However, what one means when there are more buyers than sellers is that the
quantity of buy orders is more than the quantity of sell orders.
When the amount of shares (the supply) is smaller than the
number of buy orders (the demand) the price rapidly increases.
Watching MtGoxLive over the last few weeks and months I've seen a large
stack of buy orders and fewer sell orders.
That is why when there are
alot of buy orders and few sell orders the price can rise very fast, and vise versa when there are many sell orders and few buy orders then prices can fall very quickly.

size of your buy order is larger than the size available at the ask, you should expect that some of your order might execute at a price higher than the ask.

If a market moves up one tick, it is because there are not enough sellers at the current price to fill
