I have three automated systems that trade only non day sessions, day sessions often display too much information than other times. Have another that only trades just before reports and entries have to stop so many minutes after. I don't have just one way to trade or class of symbols or combination or timeframe. It been more of interest of doing an area and then making it work through much testing. I will keep at it even though others say it can't be done, might put it on back burner for a few months of gathering ideas, but I always work at it again.
But I literally have stacks of areas I want to explore more like order flow have developed a handful of repetitive patterns but know it just small amount to be learned.
I do good amount of reversion to the mean after defining trend and each system that requires trend have different definition of trend. Most entries are never on momentum, they are entering on down close bar in uptrend, for me the longer I stay doing this, anywhere you get in has a 50/50 chance, but where I can alter percentages is risk management.
I like the challenge a great deal more than money, which for me is the only way to accumulate money. I think those who only go for the money and two for the show, three to get ready cause they often blowup go go go.
Besides ES scalping/runners, do much of Bund over night, trends nicely and cheap entries.
Unlike Science and Math where 2+2=4, best to be very open minded in trading.
