价差交易模块里的strategy定义了on_spread_tick方法，代码如下，策略启动后，并没有按照逻辑发出停止单，大佬们可以帮忙看一下问题在哪吗？

def on_spread_tick(self, tick: TickData):
    """
    Callback when new spread tick data is generated.
    """

    self.spread_pos = self.get_spread_pos()

    if self.spread_pos > 0:
        self.stop_open_algos()

        # Start sell close algo (profit taking)
        if (tick.last_price >= self.sell_price) and (not self.sell_algoid):
            self.sell_algoid = self.start_short_algo(
                self.sell_price, abs(
                    self.spread_pos), self.payup, self.interval
            )

        # Start stop close algo for long trading (stop loss)
        elif (tick.last_price <= self.buy_stop_price) and (not self.buy_stop_algoid):
            self.buy_stop_algoid = self.start_short_algo(
                self.buy_stop_price, self.spread_pos, self.payup, self.interval
            )

    elif self.spread_pos < 0:
        self.stop_open_algos()

        # Start cover close algo (profit taking)
        if (tick.last_price <= self.cover_price) and (not self.cover_algoid):
            self.cover_algoid = self.start_long_algo(
                self.cover_price, abs(
                    self.spread_pos), self.payup, self.interval
            )

        # Start stop close algo for short trading (stop loss)
        elif (tick.last_price >= self.short_stop_price) and (not self.short_stop_algoid):
            self.short_stop_algoid = self.start_long_algo(
                self.short_stop_price, abs(
                    self.spread_pos), self.payup, self.interval
            )

    self.put_event()

电脑前一天结束的时候hibernate的，第二天交易的时候需要重连CTP吗？

会问这个问题的原因是我在价差交易里用SpreadTaker下的单，log里能显示发出订单，但是没有成交的log。我每天没做重连CTP这个动作，因为新的trading session的时候，主页面日志显示是自动重连的。
