My experience is mostly with automated systems. The best
of my systems are called grid trade. They are market neutral and don't care where the market is actually going. They can be used to any market, currency pairs, cfd , indices, commodities. There are many options for the grid trade, to choose only one side, or the other, only buy or only sell. But in the end all that things dont change the way the grid works. There are expanding grids , fixed grids, and two by two grids. While all the three major type have differences they have many things in common.
