Re: Cannot transmit order (main order and stop loss orders)

 

I don't really know, but from docs: parent order should be submitted with transmit = False and child order (stop loss) with transmit = True. This way system ensures that both orders submitted simultaneously.

On related note, my logging is 10 minutes behind. It makes hard to troubleshoot.?

Do you think that could be because it saw a transmit on an individual order that wasn't part of a parent order?

Do what you think is best.
Re: Cannot transmit order (main order and stop loss orders)

 

Thank you, I saw it. I can make it look the way they showed, but I do not think it matters. They simply have two functions. One creates three orders and puts them into list. The other routine simply loops through the list and places orders.?

Ok, so I'm a polyglot :-P If you go to the docs and click the Python button at the top it will translate for you...

   38         bracketOrder = [parent, takeProfit, stopLoss]
   39         return bracketOrder

Let us know if this helps :-)

Re: Cannot transmit order (main order and stop loss orders)

 

How come the code you posted is missing this stuff that's mentioned in the docs?

            List<Order> bracketOrder = new List<Order>();
            bracketOrder.Add(parent);
            bracketOrder.Add(takeProfit);
            bracketOrder.Add(stopLoss);
            return bracketOrder;

I do not know what precautions I can check. Everything worked find a day ago.
Re: Cannot transmit order (main order and stop loss orders)

 

IDK... no errors? You check precautions?

TWS precautions can be bypassed by navigating to File/Edit ¡ú Global Configuration ¡ú API ¡ú Precautions, and check the box "Bypass Order Precautions for API Orders". Once this is done, API orders placed from a third party software will not be checked by TWS precautions.
Cannot transmit order (main order and stop loss orders)

 

I am trying to submit two orders, one main order (parent order) and the other is stop loss order. I am following TWS API documentation?
But for some reason my main order does not show in TWS as submitted. It only show us with "Transmit" option. I am expecting both order to be transmitted without any problems. Here is my Python code:

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.ticktype import TickTypeEnum
import time
import datetime
import threading
from ibapi.contract import Contract
from ibapi.order import Order
?
class TestApp(EWrapper, EClient):
? ? def __init__(self):
? ? ? ? EClient.__init__(self, self)
? ? ? ? self.nextValidOrderId = None
? ? ? ??
? ? # this is getting called upon establishing connection? ??
? ? def nextValidId(self, orderId: int):
? ? ? ? super().nextValidId(orderId)
? ? ? ? self.nextValidOrderId = orderId
? ? ? ? print("NextValidId:", orderId)
? ? ? ??
? ? def error(self, reqId, errorCode, errorString, advancedOrderRejectJson):
? ? ? ? print("Error: ", reqId, " ", errorCode, " ", errorString, "", advancedOrderRejectJson)

contract = Contract()
contract.symbol = "SPY"
contract.secType = "STK"
contract.exchange = "SMART"
contract.currency = "USD"
contract.primaryExchange = "ARCA"
?
order = Order()
order.OrderType = "LMT";
order.action = 'BUY'
order.totalQuantity = 3
order.orderType = 'LMT'
order.lmtPrice = '21'
order.transmit = False
?
stopLossOrder = Order()
stopLossOrder.OrderType = 'STP'
stopLossOrder.action = 'SELL'
stopLossOrder.totalQuantity = 3
stopLossOrder.auxPrice = 18
stopLossOrder.transmit = True

app = TestApp()
app.connect("127.0.0.1", 7497, 1)
?
api_thread = threading.Thread(target=app.run)
api_thread.start()
time.sleep(2)
?
order.orderId = app.nextValidOrderId
stopLossOrder.orderId = app.nextValidOrderId + 1
stopLossOrder.parentId = app.nextValidOrderId
?
app.placeOrder(app.nextValidOrderId, contract, order)
app.placeOrder(app.nextValidOrderId+1, contract, stopLossOrder)
?
?
app.disconnect()

What am I doing wrong?

Re: TWS API Linux - Segmentation fault - __bid64_to_string

 

I won't directly blame the machine, look very similar to same issue on Mac and Windows if using the wrong Decimal lib.
I guesstimate it around the selection of method (or a lack of)? used by linker on Decimal type. 2 mode exists: by reference/by value.

It's an old story for me now but I think I remember that libbidgcc000.a is by reference while libbidgcc100.a is by value. I use By value
Try linking with libbidgcc100.a

dangerous relocation: collect2: fatal error

Ok, I just managed to recreate this problem and (I think this may have been mentioned) but it seems to be a platform issue. The library provided by IB is built for x86_64, not i686. You can determine what your system is based on by running uname -m. If it says i686 you're going to have to go through whatever extra machinations to get things working (i.e. rebuild libbid.a, change makefile, etc).

I'm not sure why anyone would need to run their trading software on an i686 in this day and age. But, I'll freely admit I have a very old thinkpad I still like to use sometimes (just not for trading).

Anyway, that's my story and I'm sticking to it until conflicting information comes to light.

Hopefully it doesn't hurt them either though... because I just built the Cpp sample from api ver. 1019.01 and 1020.01 on...

  • bare metal running Ubuntu 16.04.7 LTS
  • kvm running Debian 11 bullseye
  • lxc container running Debian 10 bullseye
  • bare metal running Debian 11 bullseye

All of the builds succeeded and I didn't see the "dangerous relocation".

But I remember a while back someone else had that problem too. So, I can't help but wonder if somehow your environment and theirs share some kind of aberration. Was this on a fresh install?

I added?/usr/lib/x86_64-linux-gnu/libbidgcc000.a to my make file.

Re: TWS API Linux - Segmentation fault - __bid64_to_string

 

I strongly recommend to use a containerized setup for tws/ib-gateway in wsl.
If you chose ubuntu as host for wsl, then lxd (sudo snap install lxd) should do it.

There is an automated setup for a trading-environment in a lxd-container:?
If needed, you can just copy the instance to a cloud-instance or a ?real? ubuntu-machine.
