there are some semi automated systems that let you take advantage of market conditions without being biased.
when price volatility increases and it has a directional bias, people tend to be more biased in that direction which has drawbacks and advantages. The advantage is you will be trend based in your directional trades, the disadvantage is when a huge wave goes against you and your trading without stops, you can freeze up based on psychological state,(ie mental fatigue).
the automated system basically keeps you on the right side of a price swing and its done without input from the trader. The trader just asseses market conditions at that time, and decides whether to turn the system on or not. Some would call it a grey box instead of black box.
I know some people who are using computers to take advantage of slower systems and humans, in volatile situations. Mainly in FX. If I talked too much about it, others would be doing it too. There is a certain niche for these types of systems, and liquidity ceilings are high enough for the systems to work.
