Regardless, with Timescale Cloud, if you get a machine, you pay the price for that machine for as long as you use it. So I guess to avoid the confusion, we can call this just paying for the machine :)

My first ever test query was to generate minutely OHLC+volume from time,price,quantity trades. It was pleasantly easy to do:

    select time_bucket('1 minutes', time) as minutely, 
           max(price) as high,
           min(price) as low,
           first(price, time) as open,
           last(price, time) as close,
           sum(quantity) as volume
      from trades
    group by minutely
    order by minutely;
