Currently I have a bot based on Robinhood. There, I can retrieve quotes for ~400 different stocks “live” (as reasonably live as RH quotes are) in about 0.02 seconds in a single api call. (getting just 1 quote from robinhood takes 0.01 seconds, so 400x for only 2x performance impact).
I can make this call quite frequently (every 2 seconds, right now), as robinhood clearly has them all cached in the same place and just returns the latest to me all the time. Its great, very useful for my automation. I need an equivalent from Alpaca, and streaming just 30 isn’t enough for what I’m trying to do. I imagine you store all your quotes in the same cache similar to robinhood, so it would be great to just let us query more than one at once in a single API call. It’ll save a lot of overhead on both sides.
