Red, the earlier post by Tommo is similar to what I do. Basically, when a spike is the result of an attack, the price is temporarily not in equilibrium and should eventually return. So, you see if you can fade it. The trick is, to learn which spikes are, and are not, predatory attacks (some markets have heavy trading on certain clock rhythms, for instance) and, importantly, if you try to fade the spike the market-making machines will "spike again" to take you out if they have nothing better to do. In a very thin market, the mere act of making a trade will cause the market to gap a bit against you, so it's about experience and feel, as Tommo suggests.
