His exasperated statement, that he was still looking for a one handed economist , rings as true today as it ever did then. Getting two economists to agree on anything is next to impossible. Hoover s antecedent followed, in the long run, we re all dead . Well this is my approach. One point is flexibility, whilst a rigorous approach is necessary, it also must be adaptive.
Nothing lasts forever and markets and their dynamics more so than most are changing constantly.
Even trusty benchmarks, on closer examination, are really twisting chameleons. For example, the Dow Jones is perhaps the most widely watched barometer of economic activity around. Most have ended up the same way as the dinosaurs. So, trading systems too must have an adaptive nature. Everything changes and so must a trading system.
