Getting Error in Interactive Broker while connectiong through API 'error id=-1, errorCode=2104, errorMsg=Market data farm connection is OK:hfarm

Question

I keep getting the below errors while testing the below code. I've a paper trading account with IB.

Not sure what exactly these errors are. Tried searching online but could not get any hint.

 from ib.opt import Connection, message
from ib.ext.Contract import Contract as C
from ib.ext.Order import Order  
import time
def make_contract(symbol,sec_type,exch,prim_exch,curr):
    C.m_symbol=symbol
    C.m_secType=sec_type
    C.m_exch=exch
    C.m_primaryExch=prim_exch
    C.m_currency=curr
    return C

def make_order(action,quantity,price=None): 
    if price is not None:
        order=Order()
        order.m_orderType = 'LMT'
        order.m_totalQuantity = quantity
        order.m_action = action
        order.m_lmtprice = price
        print(price)

    else:
        order=Order()
        order.m_orderType = 'MKT'
        order.m_totalQuantity = quantity
        order.m_action = action
        print('hi')

    return order    

def handleAll(msg):
    print(msg)

cid = 103

conn = Connection.create(port=7497) #clietnID=888)  
conn.connect()
conn.registerAll(handleAll)
oid = cid
cont = make_contract('AAPL','STK', 'SMART','SMART', 'USD')
offer = make_order('BUY', 1, 157)

    conn.placeOrder(oid,cont,offer)

while 1:
        time.sleep(1)

Answer 1

That's not really an error, just information saying you're connected to market data. However, the conn.disconnect() disconnects before you can do anything.

Also the primary exchange for AAPL is not SMART. You don't need to put one except in rare cases where the symbol is ambiguous and it's never SMART.

Answer 2

Please add if __name__ == "__main__": in order to run order placing smoothly. By the way, the primary exchange for AAPL is not SMART, you may leave it empty as '' for the most of US stocks.
