Python 试图从TWS API请求基本数据

一般来说，我对这个api和python非常陌生，我正试图通过交互式代理从TWSAPI导入基础数据

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract

wrapper = EWrapper()
app = EClient(wrapper)
app.connect('127.0.0.1', 7497, clientId=123)

print("serverVersion:%s connectionTime:%s" % (app.serverVersion(), app.twsConnectionTime()))

contract = Contract()
contract.symbol = 'SQ'
contract.secType = 'STK'
contract.currency = 'USD'

app.reqFundamentalData(8001, contract, 'RESC', [])

以下是文档：

我无法找到此请求的数据是否已导入以及导入到何处

非常感谢任何能提供帮助的人。

请尝试以下“ReportsInstances”代码：

交互式代理API中有两个主要类处理客户端和服务器之间的消息，它们是：

1。EClient：负责向IB服务器发送请求

2。EWrapper：负责接收IB服务器返回的消息。

reqFundamentalData（）函数位于EClient类中，它负责向IB的服务器发送基本数据请求

IB服务器收到请求后，会将文本数据发送回EWrapper类，供其处理。调用EWrapper类中的另一个函数fundamentalData（），以处理返回的数据

在向IB的服务器发送任何请求之前，必须初始化EWrapper和EClient类，并覆盖相关的接收函数以实现其他个性化功能。例如打印接收到的数据，或将返回的数据保存到任何数据库等

# Import EWrapper and EClient   
from ibapi.Contract import Contract    
from ibapi.wrapper import EWrapper    
from ibapi.client import EClient    
    
    # Initilizing
    class IBapi(EWrapper, EClient):
        def __init__(self):
            EClient.__init__(self, self)
        
        # Error handling function
        def error(self, reqId, errorCode, errorString):
            print("error: ", reqId, " ", errorCode, " ", errorString)
    
        # Inherite and overwrite fundamentalData() function in EWrapper
        def fundamentalData(self, reqId: int, data: str):
            super().fundamentalData(reqId, data)
            print("FundamentalData Returned. ReqId: {}, Symbol: {},  XML Data: {}".format(
                reqId, contr.symbol, data))
            # Implement other personalized functions here
    
    tws = IBapi()                       
    tws.connect("127.0.0.1",port=7496, clientId=997)
    time.sleep(2)
    
    c = Contract()
    c.m_symbol = 'MMM'
    c.m_secType = 'STK'
    c.m_exchange = "SMART"
    c.m_currency = "USD"
    
    tws.reqFundamentalData(1, c, 'RESC', [])
    time.sleep(4)
    # Implement other requests
    
    tws.disconnect()

希望能有帮助
