In the research and development of quantitative trading strategies, issues such as the complexity of the strategy and the setting of the number of parameters often require researchers to make subjective judgments based on the actual situation and past experience. There is no fixed optimal standard. Fortunately, for the backtesting process, there are some techniques that can be used to identify overfitting problems. Therefore, we can use these techniques to try to avoid overfitting of the strategy while appropriately increasing the complexity of the quantitative trading strategy. The push analysis introduced later is an effective analysis technique when dealing with overfitting problems. #ETH #crypto2023 #Binance #whycrypto #xiaoyiclub
