Polygon streams have not been working for two days - where is the customer service or QC ? Try the stream example in the Alpaca API - A* not recognized and AM* hangs. Why is this acceptable for customers ?
I am having the same issue.
Use something more reliable i use a combination of providers alpaca being just one of them. dont be determinate to stick to one systematic approach…
i use finviz and alpha vantage for reference
