A price is nothing but sentiment that represents a balance between what people are willing to pay to buy, and what they are willing to receive to sell.
You say 'a crapload of coins', while I see your list of 0.02 orders in between the real ones of 100+ coins, that's not a crapload. If you put a load of trades in between blocks at 173 and 174, all it does is go from 174 to 173 smoothly, if they weren't there a sale of one coin would just go straight from 174 to 173.
