I have studied long ago 9 year cycle of rotation, so take highest high minus lowest low of last 9 years, backtest best parameters of last 30 years to form zones, learn how to hedge. So when price hits high parameters, I am selling/hedged, I have certain patterns to wait for that 100% of time that develop at extremes, what I don't know if it is start of pullback or major trend change. I have spent years at making better, take thousand trades a year as many add ons appear. It is a matter of being ok with many small profits, few times with losses and one lovely huge profitable trade. Am short all indexes from highs, Treasuries, recently metals, grains, softs, meats, us dollar, energies, bitcoin. Long currencies. Am up already 50% for year. Took profit on 95% of stock bought mostly from 2009, switched stock monies to futures and options. Futures time-frames are yearly, monthly, weekly, daily, intraday. I have learned how to be creative on hedging. I most likely not return to stocks again as futures and options give better returns. Have greatly reduced scalping/day trading automation keeping only best of best.
