But the questions remains...How do you flag an OCA group when sending
to/through the TWS?

There is no param that defines the group. Only on the reqOpenOrder is
their any refrence in my documentation as to OCA?

I would agree that it should be there and is of value. But where is
it defined on an upstream order send?

Ostensibly the premise one takes when using the API is you can

write

routines that are far more complex and robust than the simple One
Cancels All tag.

The reason is simple. To protect oneself from the event of an isp
failure, you place target exit and stop exit, join them as an oca
group. Then, should your program become disconnected, your

position

is protected both ways. The failing here, is on partial fills.

Use

the example of a long position. Say you have a target, it gets
partially filled, now you have a half position, and the price pulls
back to the stop. The stop order will fill, the oca logic will
cancel the leftover on the target, and there you sit, short at your
stop.

If you are trading futures, solution sounds simple. Fire off

pairs,

one oca group of target and stop for each contract you hold.

That's

where the TWS inability to report open orders can be an issue, if

you

have 100 pending, and suddenly you see a 'duplicate order' error,

it

takes a LOT of figureing to figure it all out.

No. You can call reqOpenOrders only once. Than you will got all open
orders. And I think this is ok.


I do the following in my Delphi program:

I have a List (TList object) which can stores all order data and some
additional information (ex. my internal order status, order id).

At the startup of my program and after connected to the TWS, this
List will be cleared and ReqOpenOrdeed is called. If there are open
orders, than the data of all open orders are added to the List in
OnOpenOrder event.

When I call PlaceOrder than the event OnOrderPlaced is fired if there
were no problems with sending the data to the TWS. In OnOrderPlaced I
add the order data of the placed order to the List. Of course I could
do this before calling PlaceOrder but if there are problems than I
have to delete the data.

OnOrderPlaced? The ActiveX does not give me the functionality I want
so I have rewritten the ActiveX. As I am a Delphi programmer I put
all properties, methods and events from the ActiveX into a VCL and
than extended the VCL with every function I need like OnOrderPlaced,
OnOrderFilled, OnConnectionOpened, OnOrderSubmitted etc.

When OnOrderCancelled, OnOrderSubmitted or something like this is
fired than I will search for the order id the my List and update the
order data and my internal order status.

If there are any problems with the connection to the TWS and I have
to close the TWS than my program waits until the TWS is restarted.

My program will notify when the TWS restarts. Than it searches the
Login-Window and logs in automaticly. Than it waits until the Login-
Process window disappears and tries to connect to the TWS automaticly.

I can activate and deactivate this re-autoconnect feature in my
programs option dialog window.

After successfully connected the OnConnectionOpend event is fired.
There I clear the List and call ReqOpenOrders. This will fire the
OnOpenOrders event, where the List will be filled with all open
orders.

And so on.


This works really fine for me.


Another think often read: problems with the order id and how to find
out the id for the next order or what?s the best way to calculate the
order id.

That?s what I do:

Normally, my program starts the TWS. I only start the TWS manually if
there a problems. Before my program starts the TWS I set the
entry "DDEId" to 1. You will find this entry in the USER.INI in the
folder "C:&#92;IB TWS&#92;<your crypted username>&#92;" - if your path is C:&#92;IB
TWS&#92; ;-)

The first time the OnNextValidId event is fired I allways receive 2.
But I never use this value. I just use the window API function
GetTickCount.

I never had this error message with "doublicate error id" or
something like this.

The GetTickCount function retrieves the number of milliseconds that
have elapsed since Windows was started. But be carefull: the time
will wrap around to zero if Windows is run continuously for 49.7
days ;-)


The only problem I had for a while was how to find out the folder-
name where the file USER.INI is saved. If there is only one user
which uses your program than you can take the folder name (with the
crypted user name) into your program or INI file. But if there are
more users and you don?t know the crypted users name it is a bit
difficult to find the desired folder name.

In my programs options dialog you can specify the user name and I
have written a routine to crypt the user name exactly the way the TWS
does. So I can find easyly the users USER.INI.

If somebody is interessed in this routine you can mail me.


Hope you could understand MY english ;-)

Appreciate your patience!

You're the KING!

Glad to be here!

Just uploaded my project to the files section. This is what I'm
trying to duplicate with the API - after an entry, I place a limit
target exit and a stop exit as an OCA order. Having a preset target
and stop saves time in entering the numbers and orders, specially
during fast market conditions.

The program is based on the PlaceOrder code in the files section
(Thank to Scott) - and it does what I want to do except for the OCA
part. Having an order sent as OCA to the TWS platform has an
advantage - it will guard against any sudden lost in internet
connection - at least your order is already in compared to waiting
for the API to determine whether to cancel or not. Anybody wants to
tackle the OCA part?


Thanks,

Larry

Ah! There were two problems. First, my updater thought I was running
the latest version, but it was actually 667, which did not accept
remote connections. Second, the Java socket client has not been
updated to allow one to create remote connections. It seems to work
if you comment out the code that checks that you have not set the host
and take out where it hardwires the host to 127.0.0.1.

Try opening concurrent instance of TWS on two seperate platforms.
Placing a trade on one does not update the other.

Honestly, I don't see why IB would try to make that work. They should at least warn about multiple logins to the same account though.

This explains why the TWS platform itself gets corrupted in terms of
showing orders and what not.

Try opening concurrent instance of TWS on two seperate platforms.

Log off on then on with the one that didn't place the order and
things get really screwy sometimes.

OK but answer this...

You said: "TAL is solid but does not have the fancy QCharts
recordsets."

So how does TAL set up for a depth of call in terms of numRecs and
updates?

The TAL website contains the full API docs. The RealTick charting program uses the same API so everything you want to do is possible.

You need to read the docs and decide if TAL is for you. You can also email their tech support with specific questions.

i think he is talking about running the TWS on another PC, not

connecting your client to existing one on the original PC.

I would like to know more as I used tunneling but on the secondary

PC not the original one.

That?s what I do:

TWS run?s on PC ONE in my network. And I can connect to the TWS from
PC TWO or PC THREE.

I will try to connect me to the TWS on my PC ONE from another PC not
connected to my network over the Internet. I don?t need that but I
will check it out.

开云体育

Are you sure tunneling is needed?

I can easyly connect to the TWS from any machine in my network.

Just call TWS.Connect with the IP of the computer where TWS is
running.

Example:

TWS.connect('192.168.0.1', 7496);

Like written in the docu:

host - host name or IP address of the machine where TWS is running.
Leave blank to connect to the local host.

But I think you need at least Build 769 or 770 for that.

PlaceOrder, CancelOrders. Everything works.
