In this paper, Hawkes process in point process is used for the fitting and forecast of the stock buying and selling strength and the trading strategies based on the effective forecast is provided. First, an introduction is given to Hawkes process, and its advantage in high-frequency financial data fitting is theoretically explained. Then the specific application of maximum likelihood in Hawkes model parameter estimation is described. Finally, combined with the practical case in inland stock market selected from wind database, Hawkes process is used for strength forecast, strategy construction and profitability analysis, which proves the effectiveness of the advantage and strategy of this model in actual fitting.
