I am looking for a cheaper solution as this one is about 3k per month! You have to subscribe to nyse openbook as well.

I am looking for a free or a cheap solution for. It more than 50 usd / month.
Thanjs

 

Also, I would use Interactive Broker's TWS to get the data, but there is no API for their imbalances... Or does anybody know a way to get it in excel anyway?

 

I don't need it anymore, thanks anyway!
