我在他们的API中使用了IB提供的样本，但我得到了绝对(至少从我所看到的(随机结果，这里有一些日志：

请注意，尽管Error，我仍然收到了延迟的价格。 现在(28 秒后(我在不接触任何东西的情况下重新启动完全相同的样本：

现在我没有收到任何价格！以下是调用本身的外观：
client().reqMarketDataType(3); //delayed prices
client().reqMktData(1,contract,"",true, null);
有什么想法吗？
这使用Ib_insync sdk 对我有用：
ib = IB()
ib.connect('127.0.0.1', 7497, clientId=1)
c = Contract(conId=292579214)
ib.qualifyContracts(c)
ib.reqMarketDataType(3)
ticker = ib.reqTickers(c)
print(ticker)
for obj in ticker:
print("--->{}<------".format(obj.ask))```
也许这会帮助其他人...
