The system I am currently using is biased towards trends. The complete system includes the following points:
1. Determine the style you are good at, band, arbitrage, programmatic, or other?
2. What is your entry signal, when to open a position, and what is the period of the K-line for entry?
3. Fund management, how much position do you need for the first opening, and whether to increase the position?
4. If there is a loss, what is the loss amount and maximum loss amount for the day?
5. If there is a profit, how to leave?
6. What is the maximum retracement of funds?
Design your own system rules around the above points.
