Post From: Teton spread symbol rejected for trading

Hello Sierra Chart Support,

I am using Teton routing through AMP.
I can trade outright futures, but when I try to trade an exchange-listed calendar spread symbol, the order is rejected with:

“Symbol not allowed by master firm account for trading.”

AMP told me:
“We built the back end, but you need to contact Sierra to complete. If you choose Teton, support is through Sierra.”

Could you please advise whether anything still needs to be enabled or completed on the Sierra/Teton side for exchange-listed calendar spread symbols on my account?

Thank you.
