TWS 860.9 breaks compatiblity? Or… rather internal IB problem???

Following IB “tradition” new version 860.9 of TWS breaks compatiblity with existing 3rd party software.
It gives “invalid symbol” error in many cases.

The only TWS recommended version to use is 858.6 or earlier.

If you already upgraded to 860.9 you need to revert back to 858.6

General rule is NEVER upgrade TWS until we give OK that new version of TWS is OK,
as in the past there were many cases where TWS just broke compatiblity with their previous APIs
and things just stopped working without any warning.

Again: never update TWS until we say that new version is OK.

UPDATE July 5th, 2006:

Apparently there is no problem at all with TWS 860.9 but there is a problem with *SOME* IB accounts,
that behave strangly. A couple of users reported it and I have seen strange things happening on my own account (”invalid symbol” problem) but … it all fixed itself (or rather IB has changed something to fix that) and all TWS versions (including 860.9) work OK now. No changes in software but things stop and re-start to work. The only reason that comes to my mind is that IB is doing some changes on their servers and this is causing problems on *some* accounts.


TWS fixed (858.6 or higher)

Update to previous post about TWS :
it seems that IB staff has fixed this problem as our recent tests show no problems with newest versions of TWS – 858.6 and higher.

Donate future development of IBController

UPDATE: Donations for IBController are not accepted anymore.

As you know automated trading interface for AmiBroker is provided to everyone for free. You can just download it from
Quite recently however someone asked me if there is an option to pay for IBController because he wanted to donate the development. So for everyone who wants to donate for further development of IBController I have created a payment option ($100 one time fee) here:

If you use IBController extensively and want to donate for further development you may consider spending $100 for it. Note that it is considered strictly a donation and you won’t receive any extras in return except warm feeling that you helped the development of the software you are using and guarantee that if ever IBController changes its status (i.e. from free software to commercial one), you will have license to use it and receive free upgrades.

TWS 858.4 is broken

The most recent TWS (858.4) has some serious issues, see:

So don’t install it. If you already upgraded to TWS 858 you should install previous version 857 from IB download page:
scroll down to “standalone downloads – previous versions”.

AmiBroker Feedback Center launched

Today we launched new on-line service called AmiBroker Feedback Center at:

AmiBroker Feedback Center is the area to enter feature requests / suggestions and bug reports, view issues reported by others and track development and resolution/fixes of the bugs submitted.

In not so distant future there will be voting capability added that will allow everyone to show how given suggestion is important for the community.

In order to enter AmiBroker Feedback Center please login with your AmiBroker members’ area username / password that was included in your registration e-mail.

If you forgot or lost your password you can retrieve it automatically using password reminder service at:

Note that this is “external” list (visible to all registered users) but we also manage our “internal” TO-DO list that is not exposed to the public for many reasons (competitive, technical, etc). The “internal” list contains all things submitted in the past so there is no real reason to re-submit old suggestions if they were confirmed already. But it also does not hurt if you do.

We also reserve right to add/edit/remove any entries posted in AmiBroker Feedback Center on our own discretion.
