IQFeed doesn't seem to support linux. They charge ~$444/year for API access on top of IqFeed core fee and exchanges fees.

iqfeed and NT8 historical data download

Also I wonder how's the data quality of IQFeed's intraday 1m data? I was hoping to have a look with a free trial and then decide whether to sign up (but the API fee makes the free trial not free.)
I have tried Yahoo Finance, Alpha Vantage, Twelve Data and Finnhub, and none of them have good 1minute data (lots of missing data points even for the most recent day.) I tried their free tiers. Their paid subscription is supposed to be higher in rate limit instead of data quality.

Not sure how you can validate/test data quality. This was one of my concern before going with iqfeed.Also I wonder how's the data quality of IQFeed's intraday 1m data? I was hoping to have a look with a free trial and then decide whether to sign up (but the API fee makes the free trial not free.)

For the other feeds (Yahoo Finance, Alpha Vantage, Twelve Data and Finnhub), I simply picked 20 random stocks and download their last day 1m data. For best data quality, I expect 20 * 60 * 6.5 data points. The best they give is only around 60-70%. The remaining 30% data points are missing. I haven't gone to validate the accuracy of data yet, just whether there are data points for every minute.
Would a feed like iqfeed at least provide data for every minute?
