actually this kind of attack can be executed now, for example:
now the price is 0.015 USD,
there are about 10,000,000 BTS ask order at price 0.016 USD
there are about 10,000,000 BTS short order with price limit at 0.02USD(much short order without limit in fact)
currently these order can't match, because bid price is 0.015.
but I think about 3,000,000 BTS buy at btc38 will control price up to 0.018,
So I buy 10,000,000 BTS at inside market with price 0.016 USD first
then control price to 0.018, or to 0.02
sell 10,000,000 BTS to the short at price 0.018 or 0.02.
