Re: Trying to load data asynchronously and struggling with asyncio again

 

ib.reqHistoricalDataAsync takes timeout parameter, set it to 0 and this method will not time out.
Re: ib.reqTickers() conflicts with ib.reqTickByTickData()

 

thank you for replying, I have identified the problem: the reqTickers was nested in the reqTickByTickData, so I changed the App structure. BTW do you know the function to use for nested call (even though I remember that nested asyncio and blocking was not recommended)? best
Re: Live and paper data mixed

 

What seems to be happening is the instance of IB() is keeping data and not actually sending a request to TWS. The API logs only show one request being sent per connection, not the two I was expecting from the code above.

If I have two instances of IB(), and switch between those, I get correct data. Just disconnecting, changing port, and reconnecting within the same instance of IB() seems to be causing the confusion.

Any delay between disconnect and reconnect, makes no difference as long as it's still the same instance of IB(). Could someone who maintains the library investigate?

Hi Glen,

?

I have a similar setup but do not switch programmatically between the 2 gateways. However, how about adding a delay between the switching? This would ensure connection closure.

Live and paper data mixed

 

I have a program that will place trades in either the paper or live account. I run both platforms simultaneously on the same machine. It crashes when I try get my account value after switching from one to the other because I get the first result over again. I have a support ticket in with IB, but they keep suggesting it's my code. Can anyone here create the problem to help me sort this out?

With two instances of TWS open, one paper and one live, here's the simplest code I've run to show the problem:

from ib_async import *

def ensure_connection(ib: IB, host: str, desired_port: int, client_id: int): """Ensure IB is connected to the desired port. Reconnect if necessary."""

# Check if IB is connected and if the port matches
if ib.isConnected() and ib.client.port == desired_port:
    print(f"Already connected on the desired port: {desired_port}")
    return

# If connected but on the wrong port, disconnect
if ib.isConnected():
    print(f"Connected on wrong port {ib.client.port}, disconnecting...")
    ib.disconnect()
    ib.sleep(1)

# Reconnect on the correct port
print(f"Connecting to port {desired_port}...")
ib.connect(host, desired_port, client_id)

print(f"Connected on port: {ib.client.port}")

ib = IB()

IBPort = 7496

ensure_connection(ib, "127.0.0.1", IBPort, 33) print(ib.isConnected()) print(ib.client.port)

SummaryAccountValue = ib.accountSummary() print(SummaryAccountValue)

IBPort = 7497

ensure_connection(ib, "127.0.0.1", IBPort, 33) print(ib.isConnected()) print(ib.client.port)

SummaryAccountValue = ib.accountSummary() print(SummaryAccountValue)

ib.disconnect()

print(ib.isConnected()) print(ib.client.port)

IBPort = 7497

ensure_connection(ib, "127.0.0.1", IBPort, 33) print(ib.isConnected()) print(ib.client.port)

SummaryAccountValue = ib.accountSummary() print(SummaryAccountValue)

IBPort = 7496

ensure_connection(ib, "127.0.0.1", IBPort, 33) print(ib.isConnected()) print(ib.client.port)

SummaryAccountValue = ib.accountSummary() print(SummaryAccountValue)

ib.disconnect() ''' ib.fills also seems to have problems. For the first connection, it will show correct information, but on the second connection, it will show the first plus the second.

Is there a problem somewhere in the ib_async library or is this an IB issue? Can anyone reproduce this or suggest how I can fix it?

Re: Clicking an override button

 

Hi all,

I am answering my own question. I suspect I need to specify order conditions
and allow the advancedErrorOverride flag.

How do I do this?

Re: ib.reqTickers() conflicts with ib.reqTickByTickData()

 

These two methods are very different:
?
reqTickers(*contracts,?regulatorySnapshot=False)

Request and return a list of snapshot tickers. The list is returned when all tickers are ready.

This method is blocking.

?

reqTickByTickData(contract,?tickType,?numberOfTicks=0,?ignoreSize=False)

Subscribe to tick-by-tick data and return the Ticker that holds the ticks in ticker.tickByTicks.

?

Can you post more code snippet, and more importantly what you are trying to achieve?

Hi Elat,

<snip Moreover the status gets fired once and not for each status.

PL] Ouch, that is one reason why my code is not executing the way I expect. I’ll do some tweaking.

Thanks for your input.

Re: Unable to determine when an order is submitted

 

Hi Prenav,?
?
be careful on choosing the status.. I've noticed in paper trading that stutus (PreSubmitted) could never be reached as those statuses are executed very quickly. Moreover the status gets fired once and not for each status.

ib.reqTickers() conflicts with ib.reqTickByTickData()

 

Hello Everyone, when building the APP (not in a notebook Jupyter), if call the ib.reqTickers() after having called ib.reqTickByTickData() it goes in overflow and crashes. But, if I call reqTickers() before reqTickByTickData works perfectly! I have tried with ib.sleep(30) but nothing. Any help? Thank you.
Re: Unable to determine when an order is submitted

 

Might work in simulation, but remember in real trade there will be delay after placing order:
?

? ? stop_loss_trade = ib.placeOrder(contract, stop_loss_order)

# BELOW might not be true always so quickly!

? ? if stop_loss_trade.isActive():

?

You should stick to event driven for robustness as you had before.

Hi biney59,

Thanks for your suggestion.

?

I got rid of the event logic and the program is working as I want it to at least in the simulator.

?

Here is a snippet of the modified code.

? ? # Create the limit order (parent order)

? ? limit_order = LimitOrder(order_type, order_quantity, limit_price, outsideRth=True, transmit=False)

? ?

? ? # Place the limit order

? ? print("Placing limit order")

? ? parent_trade = ib.placeOrder(contract, limit_order)

? ?

? ? # Create the stop loss order (child order)

? ? stop_loss_order = Order()

? ? stop_loss_order.action = stop_loss_action

? ? stop_loss_order.orderType = "STP"

? ? stop_loss_order.totalQuantity = order_quantity

? ? stop_loss_order.auxPrice = stop_loss_price

? ? stop_loss_order.parentId = parent_trade.order.orderId

? ? stop_loss_order.transmit = True

? ?

? ? # Place the stop loss order (this transmits both orders)

? ? print("Placing stop loss order")

? ? stop_loss_trade = ib.placeOrder(contract, stop_loss_order)

? ? if stop_loss_trade.isActive():

? ? ? ? ib.disconnect()

? ? ? ? print("Exiting")

? ? ? ? sys.exit(0)

? ? # Run the event loop to process order status updates

? ? ib.run()

?

?

Re: Unable to determine when an order is submitted

 

PreSubmitted is not the status you want, as that still does not mean active. What you want is Submitted. You can look at for different possible statuses.
?
But for your case, even simpler, trade object already has method which will verify if Submitted. Use that.
Unable to determine when an order is submitted

 

Hi all,

I am unable to determine when an order is submitted. See the below code of
my on_order_status event. What am I doing wrong? The on_order_status event
does fire. I suspect I have the if condition wrong but am not certain.


# Event handler for order status updates
def on_order_status(trade):
print("order status event fired")
if trade == stop_loss_trade and trade.orderStatus.status ==
"PreSubmitted":
print("Stop loss order submitted, disconnecting.")
ib.disconnect()
sys.exit(0)

Re: groups of events into one event

 

Thanks so much. I didn’t know about the event kit notebook…..that will be useful, or the ticker event.
Re: groups of events into one event

Hi,

You can use the event that is on the ticker.

You are referring to the ib_async.IB() events, which will emit updates for any ticker that is active. But there is a ticker event too, which will only emit when that particular ticker has updates. Which is what I think you are asking for



So use the Ticker.updateEvent of the individual ticker. By the way in eventkit there si a notebook with examples on how to use events. There are plenty of examples on how aggregate and disaggregate events.

Cheers

Hi,

I seem to remember seeing something from Ewald where he collected several events into 1....maybe Im not remembering correct as i cant find it now!!!

Asking the question an alternate way, what would be the most efficient/fastest way for say 2 sets of 5 stock portfolios to respond to events over their respective holdings, and not have to also filter through the events of the other 5 also?

Re: discrepancy with historic data

 

thanks for the responses. i realised/figured out that the open print will get the first trade after 9.30.00 which isn't necessarily the open auction.

Re: Why strike price 5635 missing from SPX option chain for 2025-03-14?

 

If it's missing in TWS, then there's no API issue (at least not on the last mile).
I doubt it wasn't available on the market, so only reasonable explanation is that the gamma was so high it hit some ceiling in TWS.
?
Out of curiosity, did you have the checkbox for local calculations selected or not? Not sure if that is the problem or not so you might want to test (including re-launching TWS after changing it).
