秒合约交易规则比较简捷，简单来说，首先必须选择要交易的数字货币。交易时间区间短为1min、3min、5min，长为60min；然后风险控制，在我们可以控制的风险范围内设定交易金额，设定盈余止损，最重要的是进行货币方向走势的技术分析。也就是说，在我们设置的交易区间内的涨跌方向，根据分析下单。

当指定了trade_id时, 返回一个成交Trade对象引用，不填trade_id参数调用本函数, 将返回包含用户当前交易日所有成交记录的一个Entity对象引用, 使用方法与dict一致, 其中每个元素的key为成交号, value为Trade，Trade继承于Entity。推荐优先使用 Order对象的属性trade_records获取某个委托单的相应成交记录, 更简单易用，仅当确有需要时才使用本函数。

is_changing(obj: Any, key: Optional[Union[str, List[str]]] = None)：判定obj最近是否有更新。当业务数据更新导致 wait_update 返回后可以使用该函数判断本次业务数据更新是否包含特定obj或其中某个字段 。如果本次业务数据更新包含了待判定的数据则返回 True, 否则返回 False。关于判断K线更新的说明： 当生成新K线时，其所有字段都算作有更新，若此时执行 api.is_changing(klines.iloc[-1]) 则一定返回True。
