Option Chain Data

steve0219 May 14, 2025, 6:16am 1

Hi,

I’m subscribed to market data from Ninjatrader & Interactive Brokers. I’m trying to get the last/bid/ask data for ZS (and other agricultural options) to show up in the Option Chain window, but it doesn’t. The data does show up in TWS. Futures market data from IB shows up in Ninjatrader.

I’m getting this message in the log:

Time	Category	Message
5/13/2025 10:56:12 PM	Connection	IB was unable to locate instrument. Please verify your symbol mapping is correct for instrument OZC_ZCF 06-25 C 425 Default

Not sure what I’m doing wrong. Please help.

Thanks,
Steve
