Interactive Brokers Broken pipe python 连接失败

Question

我正在使用 VM，Ubuntu 16.04，Python 2.7.12。我从 here 学习了一个例子。我正在使用模拟账户和交易平台。

from ib.ext.Contract import Contract
from ib.ext.Order import Order
from ib.opt import Connection, message

def error_handler(msg):
    """Handles the capturing of error messages"""
    print "Server Error: %s" % msg

def reply_handler(msg):
    """Handles of server replies"""
    print "Server Response: %s, %s" % (msg.typeName, msg)

def create_contract(symbol, sec_type, exch, prim_exch, curr):
    """Create a Contract object defining what will
    be purchased, at which exchange and in which currency.

    symbol - The ticker symbol for the contract
    sec_type - The security type for the contract ('STK' is 'stock')
    exch - The exchange to carry out the contract on
    prim_exch - The primary exchange to carry out the contract on
    curr - The currency in which to purchase the contract"""
    contract = Contract()
    contract.m_symbol = symbol
    contract.m_secType = sec_type
    contract.m_exchange = exch
    contract.m_primaryExch = prim_exch
    contract.m_currency = curr
    return contract

def create_order(order_type, quantity, action):
    """Create an Order object (Market/Limit) to go long/short.

    order_type - 'MKT', 'LMT' for Market or Limit orders
    quantity - Integral number of assets to order
    action - 'BUY' or 'SELL'"""
    order = Order()
    order.m_orderType = order_type
    order.m_totalQuantity = quantity
    order.m_action = action
    return order

if __name__ == "__main__":
    # Connect to the Trader Workstation (TWS) running on the
    # usual port of 7496, with a clientId of 100
    # (The clientId is chosen by us and we will need
    # separate IDs for both the execution connection and
    # market data connection)
    tws_conn = Connection.create("127.0.0.1", port=7496, clientId=100)
    tws_conn.connect()

    # Assign the error handling function defined above
    # to the TWS connection
    tws_conn.register(error_handler, 'Error')

    # Assign all of the server reply messages to the
    # reply_handler function defined above
    tws_conn.registerAll(reply_handler)

    # Create an order ID which is 'global' for this session. This
    # will need incrementing once new orders are submitted.
    order_id = 1

    # Create a contract in GOOG stock via SMART order routing
    goog_contract = create_contract('GOOG', 'STK', 'SMART', 'SMART', 'USD')

    # Go long 100 shares of Google
    goog_order = create_order('MKT', 100, 'BUY')

    # Use the connection to the send the order to IB
    print(tws_conn.placeOrder(order_id, goog_contract, goog_order))

    # Disconnect from TWS
    tws_conn.disconnect()

这是我的交易平台配置：

我可以连接到 TWS，因为从日志中我可以看到：

但是我不能下订单，而且我从日志中得到错误：

Broken pipe，什么意思？我该如何修复它并通过 python API 下订单？非常感谢。

Answer 1

您在程序结束时调用断开连接。我猜这就是它断开连接的原因；）

一些随意的想法。

IB 提供了一个新的 python API，所以除非您想使用 python 2.7，否则您应该使用较新的 API 作为它有更多的功能，现在可能还有更多的用户。
这不是您的程序的问题，但您调用了 connect 并且不要等待以确保您已连接。请注意，下一个有效 ID 是建立连接时发送的第一件事，您应该将其用作开始与 TWS/Gateway 交互的信号。通常你实现 nextValidId 回调并在那里调用你的启动代码，比如 placeAllOrders() 或其他东西。
大多数人在他们的程序中放置一个 sleep() 以等待它完成后再断开连接。这是个坏主意，因为你永远不知道它什么时候完成。在您的情况下，假设您想在收到订单后断开连接。您可以实现 orderStatus 回调并在它表示收到您的订单后断开连接。但是您可以在 disconnect() 调用测试之前放置一个 sleep(5) 或其他内容。
我不知道这条线是干什么的print(tws_conn.placeOrder(order_id, goog_contract, goog_order)) placeOrder 没有return任何东西，在TWS收到订单后它会发送一个orderStatus回调.
'errors' 说市场数据有效并不是真正的错误，只是信息。如果显示 'connection is broken'，那么您就知道您没有从该特定农场获取数据。
这对 goog 来说无关紧要，但主要交换从来都不是 SMART。这是您使用的合约主要进行交易的实际交易所。这仅用于消除歧义，以防 goog 在其他国家/地区以美元进行交易。
