I created these using onchain data from March 2021 to November 2022. There are 3 models i used together. The first uses eth data, the second btc data, and the third is a momentum/strength model using both eth and btc. For whatever reason eth data is more accurate for trading btc than btc data. Here they are:
If it's working for you in trading BTC and ETH and the results fine then good. but I would suggest you develop a strategy not only base on onchain data from march 2021 to 2022 , What about if you try getting or comparing data from precious years, maybe you could get more complete and accurate results from the overall years other than basing your data on this two recent years.
