AHR999 means reversal strategy AHR999, AHR999X, reconciliation mean, logarithmic price, net worth
####Overview This strategy is based on the AHR999 and AHR999X indicators. By comparing the current price with the harmonic mean price and logarithmic price, it determines whether Bitcoin is overbought or oversold, and accordingly conducts fixed investment and bottom-fishing operations. Meanwhile, the strategy also sets a take-profit condition to partially sell when the AHR999X indicator is below a certain threshold.
####Strategy Principle
####Advantage Analysis
####Risk Analysis
####Optimization Direction
####Summary The AHR999 Mean Reversion Strategy determines Bitcoin’s overbought and oversold status by comparing the current price with the historical equilibrium price and trend price, and conducts fixed investment, bottom-fishing, and take-profit operations. This strategy has a certain theoretical basis and interpretability. By combining two indicators, it can better capture the price fluctuation patterns of Bitcoin. However, the strategy also faces risks in terms of indicator failure, parameter selection, and fund management, requiring continuous optimization and improvement in practice. Overall, the AHR999 Mean Reversion Strategy provides a feasible idea for long-term value investment in Bitcoin.

* 感谢ahr999大神,后续完善可以加入一些理财,币和钱都闲着,收益会低一点,也可以放到bitfinex放借贷,年化也有十几的收益,还可以放大资金,买了币以后,就去交割合约做多,暂时想到这么多,希望大家多多交流
