Interactive Brokers管道Python斷開連接失敗

Question

我正在使用VM，Ubuntu 16.04，Python 2.7.12。 我從這里學到一個例子。 我正在使用模擬賬戶和交易平台。

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()

這是我的交易平台配置：

我可以連接到TWS，因為從日志中可以看到：

但是我無法下訂單，並且從日志中得到錯誤：

Broken pipe ，是什么意思？ 我該如何修復它並通過python API下訂單？ 非常感謝你。

Answer 1

您在程序結束時調用斷開連接。 我猜這就是為什么它斷開連接的原因；）

一些隨意的想法。

• IB提供了一個新的python API，因此，除非您想使用python 2.7，否則應使用較新的API，因為它具有更多功能，並且到目前為止可能還會有更多用戶。

• 這不是程序的問題，但是您可以調用connect，而不必等待以確保已連接。 請注意，下一個有效ID是建立連接時發送的第一件事，您應該將此信號用作開始與TWS / Gateway進行交互的信號。 通常，您實現nextValidId回調，然后在其中對啟動代碼進行調用，例如placeAllOrders()或類似的東西。

• 大多數人在他們的程序中放置一個sleep()來等待它完成，然后再斷開連接。 這是一個壞主意，因為您永遠不知道它什么時候完成。 根據您的情況，假設您想在收到訂單后斷開連接。 您可以實現orderStatus回調並在收到您的訂單后斷開連接。 但是，您可以在disconnect()調用之前放置sleep(5)或其他東西進行測試。

• 我不知道此行會print(tws_conn.placeOrder(order_id, goog_contract, goog_order))什么內容print(tws_conn.placeOrder(order_id, goog_contract, goog_order)) placeOrder不返回任何內容，在TWS收到訂單后，它將發送orderStatus回調。

• 說市場數據有效的“錯誤”並不是真正的錯誤，而只是信息。 如果顯示“連接斷開”，則說明您沒有從該特定服務器場獲取數據。

• 對於goog而言，這無關緊要，但是主交換絕不是SMART。 那是您主要使用的合約進行交易的實際交易所。 這僅用於歧義，以防其他國家的goog交易美元。
