这是我用来请求市场数据的脚本。

我还没有订阅数据馈送,所以我虽然它会自动返回延迟的市场数据,但显然我必须启用它,但找不到在哪里这样做。
这是我得到的脚本和错误,我只需要接收延迟数据,这样我就可以测试我的算法了。

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

def fundamentalData_handler(msg):
    print(msg)

def error_handler(msg):
    print(msg)

tws = ibConnection(port=7496, clientId=100)
tws.register(error_handler, message.Error)
tws.register(fundamentalData_handler, message.fundamentalData)
tws.connect()

c = Contract()
c.m_symbol = 'AAPL'
c.m_secType = 'STK'
c.m_exchange = "SMART"
c.m_currency = "USD"

print "on it"

tws.reqMktData(897,c,"",False)
sleep(50)

tws.disconnect()

错误:

文档建议(添加了重点和格式)

API 可以通过切换市场数据类型从交易者工作站请求实时、冻结、延迟和延迟冻结市场数据IBApi.EClient.reqMarketDataType

# Switch to live (1) frozen (2) delayed (3) delayed frozen (4).

从 ibapi.client 导入 MarketDataTypeEnum .reqMarketDataType(MarketDataTypeEnum.DELAYED)

或者

.reqMarketDataType(3)

必须在使用发出市场数据请求之前.reqMktData()调用它。

使用该reqMktData功能时,有四种“市场数据模式”(市场数据类型)可用:

  1. 直播(默认)
  2. 冻结(通常用于收市后的买入/卖出价格)
  3. 延迟(如果用户名没有实时市场数据订阅)
  4. 延迟冷冻(类型 2 和 3 的组合)
