Signal Strength Behind 10k Orders: Quantitative Analysis of Dongfeng Yipai M8

Anyone who trades knows that a thick limit order book is a source of confidence in market depth. But what's scariest isn't having few orders; it's someone using a large order to instantly eat up all the pending ones—that's called "slippage," where your actual execution price gets pushed away from expectations. The Dongfeng Yipai M8 breaking 10,000 orders within 4 hours of its launch looks to me like a massive market buy order suddenly appearing in the order book. The question is, how strong is the penetration power of this "market order," and will there be a reversal (closing positions) later?
