I suddenly realized a problem yesterday after working hard on it. The plan I painstakingly created takes too much time to wait for the simulated real-time data to run. In fact, I should first conduct historical market data backtesting... No one told me the order... So these days I've been building a data backtesting system. Currently, I have obtained 5 years of historical data, which happens to cover the entire bull market and one additional year. Therefore, I will first conduct backtesting based on historical data to upgrade the strategy...
