In actual work, we need to reduce the degree of overfitting of quantitative trading strategies and the degree of underfitting of strategies at the same time. The way to solve under-fitting is relatively clear, which is to constantly try various strategies, explore the inherent characteristics of trading assets based on more and better strategy models, and obtain corresponding profitability.

Most literature focuses more on the issue of overfitting, and there are many Related discussions. #whycrypto #xiaoyiclub #ETH #crypto2023 #Binance
