| Thank you for all these insights! We also went "through the ringer" finding good quality financial data, that would allow us to build a consumer web app around. I think it would be worth you time to look into Finnhub, you can tell them "Jake from Stock Unlock" referred you (if you haven't tried them already). I like to think of them as the "anti-Bloomberg", their data quality is great and their coverage is excellent. We also churned through meeting with a lot of the "legacy" data providers that have ridiculous/terrible contracts that make it complex/really annoying to build a consumer platform around. I'd love to chat more about this! Very few people have really had to dive deep on this, so it's neat meeting others that feel the pain. Lastly, the term I use is "data cartel". There is literally a financial data cartel, but I am convinced this is the decade that get's broken up, and entrepreneurs like us will have a lot more "innovation" room. Cheers! |
I can't speak to exact numbers, but I believe we were quoted like 6 figures/year for JSE and I think we pay like 4 figures/year now…? Exchanges can and do charge whatever they want…so when you need realtime data explicitly, even if you skip the data brokers, you'll just have to pay. You legally cannot use data for profit from some exchanges (if I recall, JSE is one). Some exchanges seem to have a majority of their revenue coming from data licensing.
Oh, then don't get me started on ISINs and all the failed "open source" attempts to not use ISINs and how some ISINs can be used without licensing while others require it.

My company is mostly AU/NZ (mostly because of tax, but quickly growing), so most of these data services didn't even support us until the past few years. We use a combo of like 10 data brokers to piece together coverage and we're still missing huge datasets (unfortunately Finnhub doesn't seem to cover any of them, but will look).
Luckily I focus on the Frontend/UX of our product and avoid this drama, but do feel free to reach out (contact via profile; I'm easy to find).
Good luck! I do like the idea of education, will follow. Even though I've worked in this industry for 5 years, I still find new stuff on the retail investor side of things. We'd love to educate more in our product, but we just partner with people instead..
