市场数据：IbPy

Question

我无法获得市场数据，我一直收到同样的错误，我不知道为什么。这是我的代码：

from ib.ext.Contract import Contract
from ib.opt import ibConnection, message
from time import sleep

# print all messages from TWS
def watcher(msg):
    print msg

# show Bid and Ask quotes
def my_BidAsk(msg):
    if msg.field == 1:
        print ('%s:%s: bid: %s' % (contractTuple[0],
                       contractTuple[6], msg.price))

elif msg.field == 2:
    print ('%s:%s: ask: %s' % (contractTuple[0], contractTuple[6],msg.price))

))

def makeStkContract(contractTuple):
    newContract = Contract()
    newContract.m_symbol = contractTuple[0]
    newContract.m_secType = contractTuple[1]
    newContract.m_exchange = contractTuple[2]
    newContract.m_currency = contractTuple[3]
    newContract.m_expiry = contractTuple[4]
    newContract.m_strike = contractTuple[5]
    newContract.m_right = contractTuple[6]
print ('Contract Values:%s,%s,%s,%s,%s,%s,%s:' % contractTuple)
return newContract

if __name__ == '__main__':
con = ibConnection(port = 7497, clientId = 9615)
con.registerAll(watcher)
showBidAskOnly = True  # set False to see the raw messages
if showBidAskOnly:
    con.unregister(watcher, message.tickSize, message.tickPrice,
                   message.tickString, message.tickOptionComputation)
    con.register(my_BidAsk, message.tickPrice)
con.connect()
sleep(1)
tickId = 321

# Note: Option quotes will give an error if they aren't shown in TWS
contractTuple = ('AAPL', 'STK', 'SMART', 'USD', '', 0.0, 'False')
#contractTuple = ('QQQQ', 'OPT', 'SMART', 'USD', '20070921', 47.0, 'CALL')
#contractTuple = ('ES', 'FUT', 'GLOBEX', 'USD', '200709', 0.0, '')
#contractTuple = ('ES', 'FOP', 'GLOBEX', 'USD', '20070920', 1460.0, 'CALL')
#contractTuple = ('EUR', 'CASH', 'IDEALPRO', 'USD', '', 0.0, '')
stkContract = makeStkContract(contractTuple)
print ('* * * * REQUESTING MARKET DATA * * * *')
con.reqMktData(tickId, stkContract, 'con', False)
sleep(15)
print ('* * * * CANCELING MARKET DATA * * * *')
con.cancelMktData(tickId)
sleep(1)
con.disconnect()
sleep(1)

它返回此错误：

我认为这与刻度ID有关，我需要为它附加一个不同的数字。关于我出错的地方的任何帮助都会很棒。感谢。
