May I please ask what is the difference between IEX and SIP data? More specifically:
- Is IEX live data as well?
- For SIP data can I get the order book for different ETFs (e.g. SPDN)? I’ve noticed I can get it from IEX as well, but it’s very poor quality and does not include an order book ID. Does SIP data offer better quality?
- Is there a difference between the live price quote I can see from IEX and that from SIP? Is IEX not accurate?
Additionally, may I please ask if SIP data is available for funded accounts above a certain threshold? Or do I have to make a subscription and pay 99 USD/month indifferently?
Many thanks,
M
