Do you have their service and is that what Polygon.io can do for me?Well there are 14+ public exchanges. The CTA + UTP feed are a consolidated feed of all those exchanges, which has 100% market coverage. Unless you're creating your own consolidated feed ( extremely expensive ) you'll need access to the CTA+UTP for full market coverage.
Do you create aggregate tick bars ?Yes, Polygon offers the CTA+UTP and OTC ( pink sheets ) as well. Our minute aggregate bars go back to the year 2000.
No, I mean like 200 ticks, 500 ticks, 1000 ticks...NOT minutes.@syswizard Yes, we stream minute bars
