问题
I am trying to get news feed (Broad Tape) not specific to any equity but running into error after running this code
from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import *
class MyWrapper(EWrapper):
def nextValidId(self, orderId:int):
print("setting nextValidOrderId: %d", orderId)
self.nextValidOrderId = orderId
# start program here or use threading
app.reqContractDetails(4444, contract)
def newsProviders(self, newsProviders: ListOfNewsProviders):
print("NewsProviders: ")
for provider in newsProviders:
print("NewsProvider.", provider)
def contractDetails(self, reqId: int, contractDetails: ContractDetails):
super().contractDetails(reqId, contractDetails)
print(contractDetails)
def contractDetailsEnd(self, reqId: int):
super().contractDetailsEnd(reqId)
print("ContractDetailsEnd. ReqId:", reqId)
# this is the logical end of your program
app.disconnect() # delete if threading and you want to stay connected
def error(self, reqId, errorCode, errorString):
print("Error. Id: " , reqId, " Code: " , errorCode , " Msg: " , errorString)
wrapper = MyWrapper()
app = EClient(wrapper)
app.connect("127.0.0.1", 7496, clientId=123)
print("serverVersion:%s connectionTime:%s" % (app.serverVersion(), app.twsConnectionTime()))
from ibapi.contract import Contract
contract = Contract()
contract.symbol = ""`enter code here`
contract.secType = "NEWS"`enter code here`
contract.exchange = "BRFG"
contract.currency = ""
app.run()
And the output that is returned is
serverVersion:148 connectionTime:b'20190227 22:17:03 EST'
setting nextValidOrderId: %d 1

For broad tape news you use the function reqMktData with the Contract object defined for the news provider.
contract = Contract()
contract.symbol = "BRFG:BRFG_ALL"
contract.secType = "NEWS"
contract.exchange = "BRFG"
reqMktData(1, contract, "mdoff,292", False, False, [])
