Error after installation NT8

[Merlin997]

Hi all,
after NT8 installation, when i tried to download data from IB i recieved the message "

Received unknown error/warning: End Date/Time: The date, time, or time-zone entered is invalid. The correct format is yyyymmdd hh:mm:ss xx/xxxx where yyyymmdd and xx/xxxx are optional. E.g.: 20031126 15:59:00 US/Eastern Note that there is a space between the date and time, and between the time and time-zone. If no date is specified, current date is assumed. If no time-zone is specified, local time-zone is assumed(deprecated). You can also provide yyyymmddd-hh:mm:ss time is in UTC. Note that there is a dash between the date and time in UTC notation.

"
How I can resolve this problem?

Hello Merlin997,

Thank you for your post.

I would first like to ensure that you are using the fully supported version of Trader Workstation (10.23.2a) or Gateway (10.23.2a) as outlined in our Interactive Brokers Connection Guide Below:

• Interactive Brokers Connection Guide

You may find the version you are using by going to Help > About within Trader Workstation or Gateway.

If you are not using these listed versions then I would recommend uninstalling the current version you are using and then using the download links in the Connection Guide above to install the supported versions.

You may also test by changing the timezone within Trader Workstation to CST.

Hello Merlin997,.

I have in both systems instrument format is set to UTC, however this problem still exists! So in brief: TWS API is always expect datetime to be formatted as "yyyymmdd hh:MM:ss", but NT8 sends datetime in different format! And in NT8 there is no field in Connection screen for "IB" to change datetime format!
So real solution to this issue - to provide froim MT8 information where user can change datetime used for TWS API. Please provide to users this information!
