以下是将给定代码的参数生成斐波那契数列的函数修改后的代码:

fibonacci_sequence.append(fibonacci_sequence[-1] + fibonacci_sequence[-2])
return fibonacci_sequence[start-1:-1]

```
在修改后的代码中,我们在 `return` 语句中添加了一些逻辑,如果参数的长度不在生成的斐波那契数列中,直接返回 `None`;如果参数的长度在生成的斐波那契数列中,返回 `0`。这样就可以实现将参数限制在斐波那契数列中。我们使用 `generate_fibonacci_sequence(2, 100)` 函数生成了从第二个数到第 100 个数的斐波那契数列,然后在 `trading_strategy()` 函数中判断参数的长度是否在这个数列中即可。
