In actual work, only part of the strategy or model selected for research may be adapted to the intrinsic attributes of trading assets, and the consistent intrinsic attributes only account for a part of the overall attributes of trading assets, so the strategy model is under-fitted. Fortunately, quantitative trading strategy development is not a subject that requires absolute accuracy. Even if the strategy model is not consistent with the intrinsic characteristics of the data, as long as this adaptability exists, it may bring us considerable profits. At the same time, another part of the settings of the strategy model obtained by research may have no correlation with the intrinsic properties of the trading assets. After optimization and other work, they only fit the noise in asset trading, thus causing the problem of over-fitting. . #whycrypto #ETH #Web3 #crypto2023 #xiaoyiclub
