Order rejected - reason:Invalid value in field #8016

[yc47ib]

I was trying to use TWS API to put in an options credit spread order, and got the above message. I went through everywhere but cannot find what the code 8016 means.

I tried to chat on IBKR.com with a Tech support, he just dissappeared not being able to find an answer.

Can anyone help? Thank you.

If the error code was a proprietary IBKR "errorCode=" , I would expect an equivalent "errorMSG=" output.

To update the thread, my engineer found this, and found a solution: https://interactivebrokers.github.io/tws-api/guide_updates.html

8016 is an internal code that should not have been passed to the end user, it is confusing, hope IBKR eliminate this.
