Ahr999 is a good parameter. Introduce it into your trading model. It may not be very useful for strategies such as high-frequency arbitrage, but it is still of great reference value for trend strategies. It is only when calculating the Ahr999 parameter that the position is held for 200 days. The cost can be adjusted. The short cycle should be shorter, and the long cycle should be longer. #BNB #ETH #Binance
