Too many disconnects. No live market streaming option
Response from Market DataApr 23, 2026
Thank you for the feedback. We’re sorry the disconnects affected your experience. Reliability matters, and we understand how frustrating interruptions can be. On the live streaming point, we try to be clear about the types of data delivery we currently support, but we appreciate you sharing that this was a disappointment from your perspective.

i need help to fix the spreadsheet extensions. i understand that I only have near-realtime options data. please help I am a new user. I signed up for $144/year subscription. I want to plan my options trading and need realtime options pricing data. for the most part your google sheets extension fails. please help me =OPTIONDATA(R4,"ask") gives me ?NAME error - where R4 is AAPL =IF(Y4="",0,OPTIONDATA(Y4,"ask")) gives me ?NAME? error where Y4 is contractid it works occassionally!
Response from Market DataJan 2, 2026
Thank you for the clarification—and we’re very sorry for the confusion. Your current subscription includes 15-minute delayed options data, not real-time data. That’s why you’re not seeing live prices in your formulas. If you need real-time options quotes, we do offer that on a higher-tier plan. The #NAME? error you're encountering typically indicates that the Google Sheets extension isn't fully installed or authorized. Since the formula works occasionally, it's likely a setup issue rather than a service failure. Our support team has your helpdesk ticket open and will walk you through correcting it. Once properly configured, you’ll get consistent delayed options data as included in your plan. Would you like help upgrading to real-time access, or should we focus on fixing the Sheets integration first?
