There is no reason for me to understand it if the math has no basis in engineering. I don't care about it so how would that hurt my psyche ? It doesn't, I am Instrumentalist.
Not necessarily true. My methodology right now is fully systematic (but not fully automated) and the result is reproducible by other traders if I share it. For me, the problem with automation is reduction of trade frequency. The patterns/behaviors may not fulfill 100% of code thus not detected but when my eyes see it, the price play like my assumption. The great thing is I am not glued to screen and I still can attain the normal trade frequency per month by adding other symbols.
