Without SET_ORDER_VAL this is not possible.
Just call PLACE_ORDER with transmit flag=-1 (so it goes not to IB).
Then use SET_ORDER_VAL to set the ref with transmit flag=1.

There is no information about twslink.xml. Normally no need to change it and also some parts may not have an impact at all.

Hello,
negative shares per lot factor to get fixed ordersize makes no sense in conjunction with ib_position_sync.
Because ib_position_sync itself calculates what size required in order to sync IB positions with MT positions.

Hello,
unfortunately the IBStarter is no longer developped.

IBStarter used IBController. This free open source java tool can prevent TWS from logging off.
How to use this tool is explained in this tutorial:

Hi,
you can just copy the DLL into Windows/system32 or Windows/syswow64. Depending where you need it.
But in this case, you can't use it as COM or ActiveX. Just as DLL. The setup also does a registration.

You can do this per symbol. On the contract page, double click on the contract you want to have a fix size for. In the upcoming dialog set the "shares per lot factor" to a negativ number equal to the size you like to have fix for this contract. For instance, if you like always 20, then set this fact...

Hello, i am sorry but you need to get familar with visual studio. I can't give support for Visual Studio here. The project setup is based on a python 3.6 installation on c:\python36 If your python is installed elsewhere, just change the project settings (include path and library linking) accordingly...

Hi, the API is only a protocol definition. Not more. Any API client, like TWSLink, connects per TCP/IP to TWS or Gateway and sends commands according this protocol. If the command you send via TCP/IP is not in line with what the protocol defines, TWS or gateway immediately closes connection. --- The...

I just made quick test: It works fine with TWS 972.1p on Windows 10 64 bit,

Hello, i downloaded the python wrapper project and opened it. The first thing was to upgrade the project to vc141. As platform i chosed Windows 8.1. I got similar errors like you because my python installation changed meanwhile. The point: You need to either adjust your python installation to match ...

Hello Rick, thank you for giving feedback. Good possible it is because of the version of TWS (and so API). Because TWSLink is no longer maintained, TWSLink still uses old API paradigma which will be sooner or later outdated by IB. Probably this is now the case with version 972 . But good possible yo...

What is IBGateway: The IB Gateway is a lightweighted tool used as a conjunction between Interactive Brokers and API clients like the bridge. Unlike TWS, the gateway is not closing itself. Once started it runs until closed. The gateway just provides minial functionality. You can't place orders or que...

What is different on those 2 machines ? (Same TWS,...)
What code (TWSLink function calls) is running ?
What does the logfiles tell ?

Logfiles are best place to get information.
(Usually located in C:\trade-commander\twslink2\log)

Hello,

Can you tell me what IB symbol exactly used for your MT order ? So i can try to reproduce this.
Thank you

Hello Harrison,
its long time ago i made such order.

I am sorry, i don't know, if MOO or MOC is only possible with live account.
You need to ask IB support for this.

What is the problem when placing an MOO order ?

When i remove the SET_ORDER_VAL for price and execute again, i get a new error: API-error: error validating request:-'bh' : cause - the combo details for leg '0' are invalid. - conid, ratio, side: -1, 1, 2 code=321 id=1 It points to wrong parameters provided by ADD_COMBO_LEG.

When i executed your code i get no order placed.

I don't think you can register a leg contract.
Only single contracts.

You create a leg by ADD combo leg. For this, just need a conid, not uid. I think this is still a problem in your code.

Add_COMBO_LEG returns a leg uid. This can be added to an order by SET_ORDER_VAL.

Hi, i tested first part of your code and found the expiry is wrong. change uidESopt1 = REGISTER_CONTRACT("ES","FOP","USD","GLOBEX","","20180927","P",2725,"50",0,0.0); to uidESopt1 = REGISTER_CONTRACT("ES","FOP","USD","GLOBEX","","20180921","P",2725,"50",0,0.0); or, if you can get conid, call REGISTE...

What do you mean by contract id. The ADD_COMBO_LEG expects the conid, not the contract uid. The conid is the unique id provided by IB. So for each leg, just provide its contract conid. You get the contract id by right click on contract in TWS. Then search for info menu. Select details. A website sho...
