Still using Figure 3-1 to illustrate, the data we obtained during the backtest is the data of all surviving members at the end of phase B, but at the buying and selling point pointed by the arrow, the members that can be seen also include some members in B Members leaving in stages. In the backtesting, due to problems with the data set, these members who performed poorly in phase B were directly excluded, which was a misuse of the information that could only be obtained in phase B, thus falsely improving the backtesting results of the quantitative trading strategy. #whycrypto #Web3 #BNB #Binance #crypto2023
