Re: "update order" VS "cancel and creating order"
Is this what you were looking for? Modifying or cancelling " directed" API orders incur fees. SMART routed orders do not. But executions get you credits so you only actually have to pay fees if your ratio of (#Orders Cancelled or Modified / #Orders Executed) > 25 From
Cancel/Modify Orders
| Asset/Order Origin |
Routing Venue |
Fee per Order 1 |
Execution Credit 2 |
| API/CTCI Smart |

| TWS Directed and Smart |
All |

N/A |
| API/CTCI Directed |
All |
USD 0.01 |
USD 0.25 per API/CTCI Directed execution |
Orders with a time in force that specifies an expiration time, such as GTC, will be assessed cancel fees according to the above schedule.
for cancel/modify fee examples.

| Direct Routed Order |

EUR 0.50 |
EUR 2.50 per TRADEGATE execution in the same product on the same day |
Notes:
- Unless otherwise specified, the per-order fee applies to both order cancellations and modifications.
- Execution credits are applied against cancel or modify fees for the day. Execution credits cannot exceed cancel/modify fees.

Updating an order no matter how it is routed doesn't incur a fee.

Re: "update order" VS "cancel and creating order"
I am convinced - updating is better.
Btw, I think updated limit orders are (like new ordes) re-queued into the official orderbook again. But yes, updating is also better for the OrderEfficiencyRatio.
After all, one thing, is not clear for me:
> Despair: only direct routed orders incur a cancelation fee while SMART-routed order don't
Where do you get this information? Is this also valid for updating orders or does upating orders will not incur any fees at all (independent if SMART or not). It's not transparent for me when cancelation fee incurs and when not and if updating orders also involves any fees. Would be great if anyone can share his/her experience.

Re: Shortcut for running number of subscriptions lines/rows left?
Thanks for the helpful shortcut.
1- This shows number of TWS / API data subscription lines available (which is always same??) and Top Market Data Count (currently being used).
2- It does not show Market Depth Trader Level (II) usage I think. Or at least that should be using the subscriptions lines but I only see total available subscription lines and not what is being used by Market Depth Trader Level (II).
Is there another shortcut or way in either TWS or API that I can see #2 above?
Thanks,

Hi,
I have searched but couldn't find on the mailing list and not sure where I read it but there is a shortcut (maybe hotkey) one can use to show the number of rows subscribed to watchlist or market depth level 2. Can someone please post it?
Also, is the same available via API or one has to keep their own tally in their program?
Thanks,

Better to edit: 1.Faster (one operation instead of two) 2. you keep your orderid 3. you also keep your OrderRef, if ever you use it to track/classify your orders 4. If ever you have linked orders (OCA), you keep them linked. If you cancel the parent order, all dependent orders will be cancelled too, and you need to re-create them all

Re: "update order" VS "cancel and creating order"
Besides all limitations I'd recommend always if feasible to update an existing order. This is MUCH faster than canceling and resubmitting.
For cancelation fees, isn't it true that only direct routed orders incur a cancelation fee while SMART-routed order don't?
|
Re: "update order" VS "cancel and creating order"
Yes, but I think this only a recommendation and NOT a regulation (which, if not satisfied, can punish you in any way). Does anyone has encountered problems when not fullfilling the "order efficiency ratio"? Don't think so.
|
Re: "update order" VS "cancel and creating order"
Hey, did you even bother to click through to order efficiency policy guidelines from the api web page you linked? "Modification vs. Cancellation - logic which acts to cancel and subsequently replace orders should be substituted with logic which simply modifies the existing orders."
>ds-avatar: may not count under IBKR reasonable order cancellation policy, whereas canceling it will,
I don't understant this. I cannot find any such restriction in . So where do you have this information?

Re: "update order" VS "cancel and creating order"
According to there are no hints of any such limitations or any additional information regarding the differences of cancel_and_create versus editing order (besides the "15 active orders per contract per side per account"). It's clear that editing will have the same orderId, but in my case, that's not important for me. And I cannot find any of such costs you describe.
1. I think, (correct me if I'm wrong) IB will charge for changing or cancel orders in dependent to the exchange.
2. The threshold you have to watch with frequent modifications is a maximum of 50 orders per second being sent to the TWS - that's ok. However, I cannot find any other restrictions and the important thing, why I'm asking: I cannot find the benfits of one (cancel_and_create) over the other (editing).
What are your experience? Which one you favour and why?

Re: "update order" VS "cancel and creating order"
You can unconditionally reuse order id when updating it. Also I believe updating the order may not count under IBKR reasonable order cancellation policy, whereas canceling it will, but I'm not completely sure so you might want to check this if it's important for you.
Can someone share experience about what is prefered when editing an existing order?
Should I "cancel it and create a new one" or should I only "edit it" (for example the quantity or price)? What is easier to handle? What must be take into consideration? I think (correct me if I'm wrong), for the official orderbook or the broker, "editing a limit order" is the same as "cancel the limit order and create a new one", because the order is re-queued anyway. So when using the TWS API, it does also not make any differences if "(1) editing an order" or "(2) cancel it and create a new one": (1) = (2). Am I right? Or are there hidden costs (cancellation fee or editing fee) I'm not aware of?
Thanks for your feedback.

Re: "update order" VS "cancel and creating order"
I can't answer your question fully but here are two things to consider or add to your question.
1- There are costs (not to TWS but yes to API)? and there is a threshold you have to watch with frequent modifications or IBKR will warn and suspend you?!
2- You have to first answer if there is a benefit to modifying an order VS cancelling and resubmitting (i.e. time advantage in an HFT environment might be faster with modify OR you might still want to get executed even if couldn't modify in time). If that is the case then you want Modify only anyways. But if that is not a concern then disregard #2 and only refer to #1 above.

Re: Unable to fetch fundamental data
Most other company tickers are working, including GOOGL. I'm going to take a guess that GOOG isn't available because?it's owned by Alphabet and is not the parent company. Just a guess...

Hi Mark,
Message code 430 clearly means "No fundamental data available". This means there is absolutely nothing wrong with the code.?
However, it is intriguing how GOOGLE's fundamental data can be unavailable. I also received the same error for GOOG. While AMZN and other few stocks return data with same script.?

Re: Can't seem to just get the price/greeks of an option contract in Python
Probably you're defining an incorrect underlying contract on an option contract.
You can see examples of working with that method in Testbed example.
To try without market data select delayed data type in the beginning

Can't seem to just get the price/greeks of an option contract in Python
All, I can't seem to get my script to pull down the price of an option contract. I have this overload in my class:
''' def tickOptionComputation(self, orderId, tickType, tickAttrib: int, impliedVol: float, delta: float, optPrice: float, pvDividend: float, gamma: float, vega: float, theta: float, undPrice: float):
super().tickOptionComputation(reqId, tickType, tickAttrib, impliedVol, delta, optPrice, pvDividend, gamma, vega, theta, undPrice)
print("TickOptionComputation. TickerId:", reqId, "TickType:", tickType, "TickAttrib:", tickAttrib, "ImpliedVolatility:", impliedVol, "Delta:", delta, "OptionPrice:",
optPrice, "pvDividend:", pvDividend, "Gamma: ", gamma, "Vega:", vega,
"Theta:", theta, "UnderlyingPrice:", undPrice) '''
And in my main loop I call:
'''? under_contract = createUnderlyingContract(ticker)
contract = createOptionContract(ticker, date, strike, right)
self.reqMktData(self.nextorderId, under_contract, '', False, False, [])
self.reqMktData(self.nextorderId, contract, '', False, False, [])
'''
Is there something I'm missing here? I know I need a data subscription but I don't even get the warning message about it. Thank you in advance!

Re: question about server support and login best practice
Correct. It enables you to run TWS and Gateway with automatic login. ? It has nothing whatever to do with the TWS API. ? IBKR's introduction of the auto-relogin mechanism with TWS 974 reduces the value of IBC, though it also has other functions that may be of value. And if you don't want to have to login every Sunday, IBC in conjunction with Task Scheduler (on Windows) or crontab (on Linux) can mean the whole thing is completely automatic (I can't remember the last time I had to manually start or login to my live TWS: the only reason is just occasionally when TWS gets completely screwed and won't respond, but these are very rare events). ?

Hi Richard.?
Never really paid attention to IBC although have seen it mentioned in posts. Went on your GitHub link and from what I gather it is for logging in / maintaining the login around restarts etc.? It is not meant to be a replacement for IB Api right. More of augmentation to it.?
