How do you program your algo to stop you out? Can it tell the difference between fake out spike vs. a real move? Are you telling me that flash crashes are unemotional responses? Can someone give me an example of an algo specifically designed to compete with a manual day trader?
You program your system to stop you out, that's it. Either by way of each individual trade within a system or a system itself or a basket of systems, either by time, by contracts traded or by adverse price movement. Alternatively you can be always in the market with a basket of systems and one will hedge another.
One system can fade fake out spikes another can trade a real move/trend. Some can do both and you accept the beating when there is a momentum shift in direction.
The image below is an example of a system that is designed to do what I can't do manually.
