IB DDE basic question

id = idn, where 'n' is some integer number. For orders, 'n' must always increase, even from session to session.

I used a large number for n and now all my DDE orders do not work.
They work when I use the same spreadsheet on edemo.

Is there a way to reset the idn?
I tried restarting my TWS.

How do you guys work around this idn order issue? This would be dumb if you always have to increase n even when you use it a few days later.

Thanks!
 
Anyone know the solution of how to reset the order id number used for IB DDE? Thanks!

what are you? run out of id's? :) :) :)
they must be somewhere in settings folder. so the easiest solutin would be to delete accout settings folder.
 
I tried deleting the account settings folder.
I also tried re-installing TWS and API.
Both didn't work.

There must be some easy way to reset it. :)

Here's where they said it was on the TWS api yahoo group but I never found it...

In the API directory , you have a tws.xml file... Search mapofstrings and put 0 instead of the number( big ) after it..

I never found it either so please tell me if you know where it is.
 
hhhhmm..just tried it on demo..start from order id 1 on computer,where TWS just installed(880), use few id's, delete demo settings folder-start TWS-starts from 1 again. have to say-i'm using activeX, not DDE.
maybe your order id's stored somehere in your application and you don't know about it?
 
Thanks for your ideas Bob. I guess it's different for Excel DDE.

When requesting data, it allows me to use lower id numbers like 0,1,2,3,4 and works good. I see this is true since the sample IB Excel always starts from 0 for data requests. For placing orders, IB Excel uses makeID() function.

I used IB's sample Excel DDE and it sent an order with id724688694 to see the syntax.

My Excel DDE which was at id1600+ doesn't send orders anymore since idn has to increase. I could always increase my idn to 724688695 but I rather reset it and continue in the 1600s.

I deleted the settings folder for my user but that still didn't help. Someone using the Excel DDE must've figured out how to reset this..

I think I found it but I cannot try it as I 'm trading.

In your jts folder, open the folder called dlfmqtvn( or something like that ), then open tws.xml file. In this file search for :MapOfStrings varName="ddeIdMap"

You have 2 numbers following : -1 and the last number. Replace it with 0.

If it doesn't work, go to the IB website API bulletin board and search for a thread called "duplicate order id ".They explain how to do it.

that would be a TWS accout settings folder i was talking about earlier.
you can simply delete it(all TWS settings will be lost) and then order is will be 1
