The essence of the strategy described here is a dynamic balancing strategy, which always balances the value of the coin to the value of the coin. Although designed to be pre-listed, the strategy logic is very simple. The main purpose of writing this strategy is to show all aspects of the strategy design.
Strategic logical wrapping Wrapping together some data, mark variables, and strategy logic at run time ("wrapping into objects").
Code that handles initialization tasks Initial account information is recorded at the initial run to be used for earnings calculations and whether data is recovered at the initial run based on parameter selection.
The code for strategic interaction processing A simple pause, continuous interaction is designed.
Code for the Strategic Benefit Calculation The earnings are calculated using the coin-bit method.
Key data persistence mechanisms in the strategy Mechanisms for designing data recovery
The code that shows the policy processing information The status bar data is displayed.
