Only thing safe to say, all humans will died one day.
I been going short/hedged Indexes for over 2.5 years, couple times they have hit first targets and then eventually get stopped out at breakeven and the rest get equaled out cause losses in Indexes and hedges kick in to equal out. I am still very long and few short in stocks.
I am often way too early in trading long term commodities, I have back tested enough to know my account would be wiped out if not for hedges. So you going against the major trend of Indexes without insurance, well.....
Automation averages per year 5-15% being correct on long term signals, once new trend starts, dance options around position, but deeper into trend, that becomes too dicey.
Granted, if you do find the top, it will be incredible ride, but it been 4 dozen plus attempts for me already and zero for 48+, so win/loss percentage not very good, ROFLMAO
HAPPY NEW YEAR ALL
