Hi Mat, it happened that i read some of the posts in this thread and i think i can clear one of your point about the triggering of stop losses 'at the worst price after the triggering trade' that you experienced.
Suppose that your stop buy order was at 601$. This mean that when the last trade execute above that price your stop is executed.
Now, MrStopHunter (whoever he may be) place a market buy order, consuming all liquidity up to, let's say, 610$.
Every trade is 'atomic', meaning that no other trades can happen while another trade is happening (this is pretty basic stuff).
So, only after MrStopHunter order is executed your stop order is executed too (potentially with many others). This explain this particular behavior you noticed.
But what if, 'MrStopHunter' is also 'MrBitfinex', or at least a very good friend of MrBitfinex's?
It is corrupt, but they don't have anyone watching what they are doing on thier own unregulated exchange, so it is also a very easy way to increase the income stream from the exchange.
That is what I am getting at.
