Dislikedthis is a great topic to debate
here is my take...
quant systems... there is NO universal system. however, the more universal the system, the better. its always a good sign to see a system work on the EUR/USD and the USD/JPY, as the pairs have very different characteristics so the system must be robust to be profitable in both. it would be even better to see the system work on a completely different market like crude oil. with this said, most of my quant systems are taking advantage of market inefficiencies that only exist in a very specific place. therefore, i trade very few universal-type systems. in quant trading i feel its more profitable to have a tight focus.
discretionary trading... YES, there are universal strategies that work. as i have pointed out many times, i usually trade the "human element" of the market (ie reading the order flow and guessing what the major players are thinking/doing). i use the same exact philosophy in the stock market, currencies, oil, bonds, you name it. and it works everywhere, in every timeframe from 5mins to 5years, because the human element remains the same everywhere. so while i dont believe in universal systems, i certainly believe there are universal strategies and approaches that are profitable in every market in every timeframe.Ignored
