Ibpy with Interactive Brokers API not working

Question

I feel there is something fundamentally wrong. I go from example code to example code trying each out and I have never had any success.

Below is a collection of scripts Ive run and the response. Most of these scripts come from example found here on StackOverflow for which the person seems to have success with (after some help). Alas I have no success and just feel there must be something really wrong with what Im doing.

Before I start with the scripts that dont seem to work here are my configs for Interactive brokers GUI, TWS.

API - Settings

checked: Enable ActiveX and Socket Clients. unchecked: Enable DDE clients. unchecked: Read-Only API. checked: Download open orders on connection. checked: Include FX posistions when sending portfolio. checked: Send status updates for EEP. Socket port = 7496. checked: Use negative numbers to bind automatic orders. unchecked: Create API message log file. unchecked: Include market data in API log file. unchecked: Let API account requests switch user-visable acc subscription. Logging Level = Error. Master API client ID = 100. Timeout to send bulk data to API is 30 seconds. Component Exch Separator = Blank (no entry here). checked: Allow connections from localhost only.

API - Precautions checked: Bypass Order Precautions for API Orders. everything else all unchecked in this tab.

Example 1.

#test_conn.py

from ib.opt import ibConnection
con = ibConnection(port=7496,clientId=100)
print(con.connect())

Running script and response

C:\Users\alex>python test_conn.py
Server Version: 76
TWS Time at connection:20160314 16:13:59 ICT
True
True

I think I can make a connection to TWS then?

Example 2.

#test_portfolio.py

from ib.opt import ibConnection, message

def acct_update(msg):
    print(msg)

con = ibConnection(port=7496,clientId=100)
con.register(acct_update,
             message.updateAccountValue,
             message.updateAccountTime,
             message.updatePortfolio)
con.connect()
con.reqAccountUpdates(True,'DU358588')

#don't forget to disconnect somehow when done
con.disconnect()

Running script and response

C:\Users\alex>python test_portfolio.py
Server Version: 76
TWS Time at connection:20160314 16:25:59 ICT

C:\Users\alex>

So nothing gets returned?

Example 3.

#test_mkt_data.py

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

def my_callback_handler(msg):
    inside_mkt_bid = ''
    inside_mkt_ask = ''

    if msg.field == 1:
        inside_mkt_bid = msg.price
        print 'bid', inside_mkt_bid
    elif msg.field == 2:
        inside_mkt_ask = msg.price
        print 'ask', inside_mkt_ask

tws = ibConnection()
tws.register(my_callback_handler, message.tickSize, message.tickPrice)
tws.connect()

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

tws.reqMktData(1,c,"",False)
sleep(25)

print 'All done'

tws.disconnect()

Running script and response

C:\Users\alex>python test_mkt_data.py
Server Version: 76
TWS Time at connection:20160314 16:31:54 ICT
All done
Exception in thread EReader (likely raised during interpreter shutdown):
C:\Users\alex>

Again, nothing gets returned?

Example 4.

#test_historical.py

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

def my_account_handler(msg):
    print(msg)

def my_tick_handler(msg):
    print(msg)

def my_hist_data_handler(msg):
    print(msg)


if __name__ == '__main__':

    con = ibConnection(port=7496,clientId=100)
    con.register(my_account_handler, 'UpdateAccountValue')
    con.register(my_tick_handler, message.tickSize, message.tickPrice)
    con.register(my_hist_data_handler, message.historicalData)
    con.connect()

    print(con.isConnected())

    def inner():

        qqqq = Contract()
        qqqq.m_secType = "STK" 
        qqqq.m_symbol = "GOOG"
        qqqq.m_currency = "USD"
        qqqq.m_exchange = "SMART"
        endtime = strftime('%Y%m%d %H:%M:%S')
    print(endtime)
        print(con.reqHistoricalData(1,qqqq,endtime,"5 D","1     hour","MIDPOINT",0,1))



        sleep(10)

    inner()
    sleep(5)
    print('disconnected', con.disconnect())
    print(con.isConnected())

Running script and response

C:\Users\alex>python test_historical.py
Server Version: 76
TWS Time at connection:20160314 16:38:03 ICT
True
20160314 16:38:04

There is no historical data? Take away the "print" in "print(con.req..." still make no difference.

running and response

Server Response: error, <error id=-1, errorCode=2104, errorMsg=Market data farm connection is OK:afarm>

So nothing seems to work and I feel like there is just something fundamental I have missed? I have got TWS logged in and running when I run the python scripts and the TWS API settings (see above) seem correct in regards to what everyone else is saying online.

Any help much appreciated.

Answer 1

I tried the codes you provided.

Example 2. Add sleep(1) before con.disconnect()

Example 3. tws = ibConnection() should be changed to tws = ibConnection(port=7496,clientId=100)

Example 4, "1 hour"--> too many spaces, leave only one space and delete extra ones.

Example 5. Be careful with the next valid order id. It should be greater than the order id in Ib system. you may use the following code to get the next valid order id from system.:

def save_order_id(msg):

    print('Next Valid ID is ' + str(msg.orderId))

con = ibConnection(port=7496,clientId=100)

con.register(save_order_id, 'NextValidId')

con.connect()

sleep(1)

con.disconnect()

You are good to go with the above changes.
