请教一下各位大佬，TickData部分字段的意思！ 有对应的说明文档吗？

@dataclass
class TickData(BaseData):
    """
    Tick data contains information about:
        * last trade in market
        * orderbook snapshot
        * intraday market statistics.
    """

    symbol: str
    exchange: Exchange
    datetime: datetime

    name: str = ""
    volume: float = 0      
    turnover: float = 0    
    open_interest: float = 0   
    last_price: float = 0    
    last_volume: float = 0 
    limit_up: float = 0
    limit_down: float = 0 

    open_price: float = 0
    high_price: float = 0
    low_price: float = 0
    pre_close: float = 0

没有，请问你哪个字段不清楚呢？

turnover和open_interest是期货中用的。
limit_up和limit_down是涨跌停。
