以下是一个简单的量化合约Java编程代码教程：
代码语言：javascript复制javaCopy codeimport java.util.Scanner;
{
public class TradingBot {
private static double currentPrice;
private static double lastPrice;
private static boolean isBought;
private static double profit;
}
}
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the initial investment amount: ");
double initialInvestment = scanner.nextDouble();
{
}
while (true) {
// Get the current price from an API or exchange
currentPrice = getCurrentPrice();
if (lastPrice == 0) {
lastPrice = currentPrice;
}
}
if (currentPrice > lastPrice && !isBought) {
// Buy at the current price
double quantity = initialInvestment / currentPrice;
System.out.println("Buy " quantity " units at " currentPrice);
isBought = true;
} else if (currentPrice < lastPrice && isBought) {
// Sell at the current price
double quantity = initialInvestment / currentPrice;
{
profit = (currentPrice - lastPrice) * quantity;
System.out.println("Sell " quantity " units at " currentPrice " for a profit of " profit);
isBought = false;
}
lastPrice = currentPrice;
}
}
}
private static double getCurrentPrice() {
// Call an API or exchange to get the current price
// This is just a placeholder method
return 1000.0;
}
}这个量化会不断地检测当前价格，如果价格上涨并且尚未购买，则以当前价格购买。如果价格下降并且已经购买，则以当前价格出售，并计算利润。
这只是一个非常基本的例子，真实的量化会使用更复杂的策略和指标来做出选择。
