I store everything in a database, including the order details and the order
id.
When you have a Limit order which doesn?t get executed, and you disconnect,
close TWS, open TWS, and reconnect through the API to TWS, then TWS forget?s
the API order ID.

So I decided that I cancel all open orders manually in TWS and then send all
open orders again from my programm to TWS.

Betreff: twsapi: Re: order IDs


Hi there -

I would like to know how you manage order ids from session to
session. I meant you place an order and store the order id in your
table, what if the TWS/Windows crashed, and you need reboot the
machine, how do you change/cancel your open orders? Thanks

That means storage of your trading events on a hard drive and with

backup.

I choose to use the Microsoft .mdb format and access it from VB

with DAO 3.6.

There is a table of trades. It has an entry order number and an

exit order number in each record. There are lots of other fields to
keep track of when, where, and why.

A recordset RS.TradesEnter is created indexed on the

openOrderNumber.

A recordset RS.TradesExit is created indexed on the exitOrderNumber.
They both point to the same table.

Creating a unique entry order number is as follows.
RS.TradesEnter.MoveLast
thisEntryOrderNumber = RS.TradesEnter![openOrderNumber] + 2
thisExitOrderNumber = thisEntryOrderNumber + 1
Now create a new trade record.
RS.TradesEnter.AddNew
RS.TradesEnter![openOrderNumber] = thisEntryOrderNumber
RS.TradesEnter![closeOrderNumber] = thisExitOrderNumber
RS.TradesEnter.Update

When a fill arrives, whether partial of full, RS.TradesEnter

updates the when,where,why fields.

When you or your ATS decides to close a position,

RS.TradesExit "seeks" this ExitOrderNumber and updates the when,
where, why fields.

That should keep you and the IRS happy.

I wonder....wanting of more Ticker's....
[in regards to the 40 ticker limit to API users]

If one logged on through multiple instance of the API moduel via an
array or segragate naming could they pull more than 40 or multiples
of 40?

I will bet ya dozen Krispy Kreme your good to go....

Dim iTemp As Integer

For iTemp = 0 To UBound(TWS1)

TWS1(iTemp).connect "", 7496 + iTemp

Next iTemp

If id <= 39 Then

TWS1(0).reqMktData(yada yada)

Else If id > 39 And id <= 79 Then

TWS1(1).reqMktData(yada yada)

End If

makes one wonder doesn't it?

If anyone has time to burn give this a rip and see if it works...I
will get around to it eventually but I am focused elswhere...

Yhoo TWSAPI

There is nothing in the files section that specifically deals with
trailing stops...though I can asure you that someday not to long from
now it will

As TonkaDad said there is a demo server

To log in:

Username for equities demo: edemo

Username for commodities demo: cdemo

And in both of the above cases the password is:

demouser


As to your trailing stop question:

It is my understanding that this can be handled in a few different
ways:

Method A:

Have no server sided order and have an order on your client side that
is ready to execute. You track the security price on your side, then
if and when certain price events occur, you do one of two things:
modify the ready order, or go ahead and send it

Method B:

Have a standing order on the server, and if and when price events
occur one of two things happens. You do nothing and the standing
order is executed on the server side (you got stopped out), Or, You
resubmit the order with modifications using the identical id # (not
positive about this one), and the server sided order is modified (an
event occured that triggered your modified order to send).

Method C:

Have a standing order on the server side, and when events occur
either one of two things happen. The order triggers (you were stopped
out), or you cancel the order and resubmit a new order with your new
parameters based on a price action event.

I havn't explored the nuts and bolts of it yet...but that is how I
believe it is played out. Which method one chooses is a matter of
prefrence and the liquidity of the market you trade.

If you go to on the left

about half way down

it should say "Files" there is some code there. Also Jaba put

together a simple project that you can download look at post 189.

As far as testing before you go live IB has a demo that you can

connect to.

Good luck,

Hi,

First post in this forum. I hope this question han't been posted
before.......

The only thing that I'm really missing is a trailing stop.
Anyone managed to code something like that?
If so please mail me the code or point me to an example.
It would save me huge amounts of time.
Finally away from the screen for a few hours :-)

I can code a bit in VB6. Level... erm... advanced 'Hello world' ;)
But if anyone would be so kind to share a few lines of code that
modifies an order I have enough to build on.

Is their a way to test without placing real trades?
Needless to say a little bug can cost 1000's........

Looking forward to the replies.
And to the founder(s) of this group: Great initiative!

Kind regards.

Hi,
i tried to run autostoptrailing using dde interface and the example
from tws manuel. It didn't work properly. Any idea's ?

Thx for help

Hi, I'm Techguy:

I started an IB Automation thread at Wealth Lab, under the Automation
Category. Click here to read it. It may have some value to you, and
will certainly expose my limited programming ability - but there may
be some good information there for you as well.



Some of you may know me from elsewhere - other forums - same guy. If
you are in the Seattle or Portland area, we have a group of Trader
Programmers that meet regularly: Here is the contact info:

The PDX and Seatac Wealth Lab User Groups are now centralized at the
Yahoo Groups area. Members can post, view the calendar, upload files,
chat, and generally keep themselves informed of the PDX WLUG
happenings.

Membership is by moderator acceptance. Content is un-moderated.

All Backtesting / Trading suite Users / Programmers / Developers are
invited to attend (Tradestation, AMI, SmartQuant, Wealth Lab, C++
Users, etc. . . are invited to attend and participate in the
meetings - if for nothing else comradiere)

This User Group strives to meet monthly, and address topics of
interest to Trader Programmers. Emphasis is on the use of Wealth Lab
for Trading strategy testing and as use of a decision engine for
Trading automation.

For a brief synopsis of the groups and more about what we are all
about go here:



A link to Wealth Lab is located on the page above.

For the Portland Oregon Wealth Lab User Group (PDX_WLUG) go here:

Odd lots do not have to be represented in the NBBO. They do have

to

trade if given the opportunity though.

So does this mean that I can put a buy and a sell order inside the
spread, and if the orders are odd lots, they are effectively
invisible, at least on the level 1? I'm thinking there must be a
huge disadvantage to this, like full lots are given execution
priority (at that level), or it would be too advantagous.

FYI, I know IB forbids you from making markets in options. I
wouldn't be surprised to see something similiar in stocks. I know
back in the old days it was not legal for complete automation, even
on a fully certed OTC dealer desk.

I tried it out on my account it indeed, it does work for stocks.
There's a specific regulation in the options market that forbids
opening two opposit positions on the same option (something to that
effect). I dont' think it exists for stocks, unless someone knows
better.

I have seen similar programs in the forex market (where the market
makers are real A**holes, more so than any equity MM can ever be).
I'm surprised that they aren't more prevasive in the equity market,
or at least, I know they exist but they are never advertised. Does
anyone know the reason?

Cheers,

JS

Subject: twsapi: Market Making App


Hello. I'm a seasoned vb programmer and I've been trading with

IB

for a long while. I'm thinking about writing a fully automated
Market Making application that posts bids/asks automatically. I

have

to admit, although I would have no problem writing the software
(which I don't mind sharing with everyone), I don't think I know
enough about market making. In general, when I try to post a

test 10-

share sell/buy on a NASDAQ stock inside the bid/ask spread, it
doesn't seem to show up on the Bid/Ask. Is this because I'm not
posting lots? or is there some other restriction. I would love

to

hear from people with similar interest, and get a move on this
project if it is feasible.

Cheers,

That was an excellent question

Anyone know how to get account number >>?

I think you need to control this yourself and keep a cross refrence
with which instance you are calling the connect from.

In this case you need to either capture the port and compare it when
you call it, or better yet keep an array that mirrors your API object
array interms of indecies

Such as a Long, 2 dimensional array that has as many lead indecie as
you have API objects and as many columns as you feel fit to
include...2 in this case...that would look something like this


Dim arrAccount()
ReDim arrAccount(UBound(TWS1), 1)

arrAccount(0,0) = 7496
arrAccount(0,1) = 'some account number
arrAccount(UBound(arrAccount),0) = 7497
arrAccount(UBound(arrAccount),1) = 'some other account number

Then when you call any TWS you can refrence the array as well and
return the account number easily based on the index API object.

You could add a third element to the array and make the array variant
and put a string value in the third slot such as "Stocks"
or "Futures" to further expand its utility.

Hope this helps as well

Scott

PS I will be exploring this subject in depth some time in the coming
couple of weeks and will be posting example code...

Unless of course you beat me to it

point to explore.

Based on a cursory review of the methods and calls, there is no way
to retrieve an account number.

But on a little deeper look I believe I have a solution for you.

Apparentley the TWS platform remembers the socket port you called
with the account you called.

In other words you must log onto to each account from a different
socket port with seperate instance of TWS, and then from within

your

program you can call the connection from a seperate instance of the
Active X componenet for each account.

An array of controls would do the job...

TWS1(0).Connect "", 7496
TWS1(1).Connect "", 7497

or perhaps just renaming the controls

TWS1.Connect "", 7496
TWS2.Connect "", 7497

I am an array kind of guy so I would go the array route...

Lastley, perhaps you dont even need the second instance and can

call

direct..

TWS1.Connect "", 7496
TWS1.Connect "", 7497

But this looks like your asking for trouble and corupted data...IMHO

Either Way....

From there, you can then refrence your calls and segregate returns
based on the source of the call

TWS1(0).reqMktData(da dee da)
TWS1(1).reqMktData(da dee da)

Thats how I see it.

Again, I havn't explored this in detail and perhaps I am wrong.

Give that a shot and then report back here what you find so we can
all benefit from your experience.

the app is running (build 769.1) and logged in to EDEMO account.

It

I'm using Python to connect, code as follows:

tws = Dispatch("TWS.TwsCtrl.1")

which works and creates the object exposing all it's methods and

However, when I try to connect:

tws.connect('', 7496)

Anyone done it this way or am I missing something obvious?

Found this on silicon investor IB board. I tried stockwatchpro along
with IB today, works pretty good. I wish IB removed BEST routing
restriction on its API.

Stock Watch Pro 2.3 with IB TWS integration just got released. Orders
can be initiated from Stock Watch Pro as follows:
- QuoteSheets (double-clicking on bid or ask)
- Level II or Island book (double-clicking on a market maker)
- Charts (from the right-click menu)
- From alerts when they trigger. SWP formula language allows you to
define any condition and associate an order with it.
