有好意思又开一个

更新数据时候

ib_gateway.py

Traceback (most recent call last):

TypeError: can't subtract offset-naive and offset-aware datetimes

换掉pytz的原因？
`@dataclass
class HistoryRequest:
"""
Request sending to specific gateway for querying history data.
"""

symbol: str
exchange: Exchange
start: datetime
end: datetime = None
interval: Interval = None

def __post_init__(self) -> None:
    """"""
    self.vt_symbol: str = f"{self.symbol}.{self.exchange.value}"`

寫給後人看
我遇到跟樓主一樣的問題 debug 後發現 end 和 req.start 的時區不同導致的
後來改了一段 code 就好了

delta: timedelta = end - req.start(tzinfo=LOCAL_TZ)
