IB can only get up to 1.1k (10 booster packs)... anywhere I can get streaming data for all NYSE/ARCA tickers? Thanks
hmm...just found out that IB's imbalance is only total imbalance, not actual market imbalance. anybody knows where to get market imbalance?
I found this: https://marketchameleon.com/Reports/StockOrderImbalanceReport it says 15 minutes delayed so useless. I wonder if you are a paid subscriber, you would get realtime.
