I'd like to see proof of that if you have it. I don't believe that Novacoin has been to $20USD before. Am I missing something? How would you have seen those open orders to say such a thing?
Novacoin hasn't been to $20 before, this is correct. I didn't mean that those orders were in the book before today. What I meant is that somebody uses a trading bot to create those orders on the fly (they would be very tedious to enter manually). He's been doing it for a long time and I don't think anybody pays much attention to it, I certainly don't. It's the big orders that move the market.
In case you didn't know it, you can view a larger part of the order book here than on BTC-e itself:
