Price data is static coming from Alpaca for certain stocks but not others

My program works well for certain stocks like AMD and NVDA but when I go to do the smaller stocks that are from the NASDAQ or NYSE the price pulled from Alpaca is static (the same for every second). My program pulls price once every second for 15 seconds and then closes. It calculates the starCBands perfectly for AMD and NVDA. It does not work for GOOGL, AHT, CLVT and others. I am only using the paper side right now as I’m still in testing. Does the test side limit the stocks you can pull live simulated data from? If this is the case, can I get a list of the stocks that I can use on the test side that are lower value stocks?
