Took me a year in 1990s to backtest and trade then automate eventually, then starting in 2010 few years to get it "down", thousands of hours, bought historical amount of option data on stocks and futures. I had developed turning patterns so learned how to hedge so lose less on pullbacks. Also learned how to profit options using directionally. Where most traders think I keep hedge on all the time is incorrect, beginnings of new trade has most risk, when instrument goes a percentage, I lift hedge, if underlying hits stop loss I keep hedge open till recovers loss plus more if chart reads continuation. There are times I lose, when one side is lifted and goes other way but even there I lose less then whatever full lose would have been if I not hedged at all. Man, I have been doing this a long time....amazing what you can do if you keep at it.
