Hi, Does anybody out there know of or even better have experience using stochastic, non-deterministic trading algorithms? So just to be very clear about what I am looking for: A trading strategy that implements an element of probability/chance. So such a trading strategy if backtested on the same historical data over and over would yield different results every time. I know they exist but don't know how widespread their use is in the real world. I don't really care about how successful they might or might not be when run on actual markets. _ I would be really grateful for any knowledge of such trading algorithms._ _ Thanks in advance._
