Post From: TT Connection Rejecting NG (NYMEX) Orders – Instrument Not Found Error

Hi,

I’m unable to place orders for NG on CME (NYMEX) using the TT connection. The orders are getting rejected and Sierra Chart is showing the following message:

“TT Futures Order Routing (Order reject). Info: TT order update (Rejected). Text: TT FIX: [Instrument not found by NAME=NGF6 symbol=NG7]SecurityAltID = NGF6, SecurityAltIDSource = 98. Text: Parent order”

Can you please check why these NG futures orders are not passing through and confirm if there is a configuration or symbol mapping issue?
