Question

有很多例子说明如何从盈透证券获得特定资产的价格。但是，当我想获得一个资产的整个选项链时，我不知道列出了哪些特定的攻击。期货相同，我不知道目前有哪些到期日。因此，对于选项，我只是遍历所有可能的攻击并且每个reqMktData，每100条消息也会sleep(1)，以避免达到每秒请求数的限制。显然，其中许多消息都返回错误“没有找到请求的安全定义”。

这看起来是错误的方法，因为它浪费了很多时间在不存在的资产上。有没有更干净的方法来做这个，或者为此目的的特殊功能？

按照Donn Lee的建议实现contractDetailsEnd的处理程序。感谢shashkello和Donn Lee。

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

def watcher(msg):
    print msg

def contractDetailsHandler(msg):
    contracts.append(msg.contractDetails.m_summary)

def contractDetailsEndHandler(msg):
    global DataWait
    DataWait =  False

con = ibConnection()
con.registerAll(watcher)
con.register(contractDetailsHandler, 'ContractDetails')
con.register(contractDetailsEndHandler, 'ContractDetailsEnd')

con.connect()

contract = Contract()
contract.m_exchange     = "SMART"
contract.m_secType      =  "OPT"
contract.m_symbol       = "VTR"
#contract.m_multiplier   = "100"
contract.m_currency     = "USD"


con.reqContractDetails(1, contract)

contracts = [] # to store all the contracts

DataWait = True  ;  i = 0
while DataWait and i < 90:
    i += 1 ; print i,
    time.sleep(1)

con.disconnect()
con.close()

print contracts

我很久以前就开始与IbPy合作，并且在样本中看到datetime成语，现在在上面的答案中。因为time.sleep有一个在后台运行的线程，因此在该线程中调用接收方法/函数的消息，所以转向基于ibpy的方法似乎很自然。

这里是上面两个合同规范的代码和输出。

queue

输出：

from __future__ import (absolute_import, division, print_function,)
#                        unicode_literals)

import sys

if sys.version_info.major == 2:
    import Queue as queue
else:  # >= 3
    import queue


import ib.opt
import ib.ext.Contract


class IbManager(object):
    def __init__(self, timeout=20, **kwargs):
        self.q = queue.Queue()
        self.timeout = 20

        self.con = ib.opt.ibConnection(**kwargs)
        self.con.registerAll(self.watcher)

        self.msgs = {
            ib.opt.message.error: self.errors,
            ib.opt.message.contractDetails: self.contractDetailsHandler,
            ib.opt.message.contractDetailsEnd: self.contractDetailsHandler
        }

        self.skipmsgs = tuple(self.msgs.keys())

        for msgtype, handler in self.msgs.items():
            self.con.register(handler, msgtype)

        self.con.connect()

    def watcher(self, msg):
        if isinstance(msg, ib.opt.message.error):
            if msg.errorCode > 2000:  # informative message
                print('-' * 10, msg)

        elif not isinstance(msg, self.skipmsgs):
            print('-' * 10, msg)

    def errors(self, msg):
        if msg.id is None:  # something is very wrong in the connection to tws
            self.q.put((True, -1, 'Lost Connection to TWS'))
        elif msg.errorCode < 1000:
            self.q.put((True, msg.errorCode, msg.errorMsg))

    def contractDetailsHandler(self, msg):
        if isinstance(msg, ib.opt.message.contractDetailsEnd):
            self.q.put((False, msg.reqId, msg))
        else:
            self.q.put((False, msg.reqId, msg.contractDetails))

    def get_contract_details(self, symbol, sectype, exch='SMART', curr='USD'):
        contract = ib.ext.Contract.Contract()
        contract.m_symbol = symbol
        contract.m_exchange = exch
        contract.m_currency = curr
        contract.m_secType = sectype

        self.con.reqContractDetails(1, contract)

        cdetails = list()
        while True:
            try:
                err, mid, msg = self.q.get(block=True, timeout=self.timeout)

                break

            cdetails.append(msg)  # must be contractDetails

        # return list of contract details, followed by:
        #   last return code (False means no error / True Error)
        #   last error code or None if no error
        #   last error message or None if no error
        # last error message

        return cdetails, err, mid, msg


ibm = IbManager(clientId=5001)

cs = (
    ('VTR', 'OPT', 'SMART'),
    ('ES', 'FUT', 'GLOBEX'),
)

for c in cs:
    cdetails, err, errid, errmsg = ibm.get_contract_details(*c)

    if err:
        print('Last Error %d: %s' % (errid, errmsg))

    print('-' * 50)
    print('-- ', c)
    for cdetail in cdetails:
        # m_summary is the contract in details
        print('Expiry:', cdetail.m_summary.m_expiry)


sys.exit(0)  # Ensure ib thread is terminated

Answer 3

自己想出来。

有一项功能可以请求列出的证券的详细信息reqContractDetails。请求E-mini SPX期货（符号ES）的一些示例代码如下所示。

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

def watcher(msg):
    print msg

contracts = [] # to store all the contracts
def contractDetailsHandler(msg):
    contracts.append(msg.contractDetails.m_summary)

con = ibConnection()
con.registerAll(watcher)
con.register(contractDetailsHandler, 'ContractDetails')
con.connect()

contract = Contract()
contract.m_symbol = "ES"
contract.m_exchange = "GLOBEX"
contract.m_currency = "USD"
contract.m_secType = "FUT"

con.reqContractDetails(1, contract)

time.sleep(2)

con.disconnect()

现在合同已保存在contracts列表中，我们可以通过以下方式获得所有可用的到期日期：

for c in contracts:
    print c.m_expiry

输出：

显而易见，这也可以扩展到选项。
