Hi All,

First day on SC.

I am trying to trade my Interactive Brokers account from SC.
I have Pack 11, Denali Feed US & Total View.

Setup as per the guide.

Interactive Brokers Trading Service

I am on TWS Desktop trying to Trade SPY.

The symbol i want to use in SC is SPY_MBO.

When i try to trade SPY_MBO i get this message:
2025-12-01 12:05:14.802 | Symbol Error | (unknown symbol with ID 2612) is unknown, unavailable, or improperly formatted. No security definition has been found for the request
2025-12-01 12:06:23.704 | Trading server did not acknowledge new order | Symbol: SPY_MBO | TradeAccount: DUxx | InternalOrderID: 6474 | ServiceOrderID: 2614 | Current Status: Order Sent *

If i switch the chart in SC to SPY, i get this error.
2025-12-01 12:06:40.417 | Symbol Error | (unknown symbol with ID 2629) is unknown, unavailable, or improperly formatted. The contract description specified for SPY is ambiguous; you must specify the currency.
2025-12-01 12:06:56.662 | Trading server did not acknowledge new order | Symbol: SPY | TradeAccount: DUxx | InternalOrderID: 6489 | ServiceOrderID: 2629 | Current Status: Order Sent *


Please help with how to map SPY_MBO to SPY in TWS. I suspect i have missed a step somewhere.
Thanks in advance.
