Dear Bitstamp!
We regularly fetch prices from various exchanges using standard https protocol. So its really sad for us that we have found that you are updating your http api ticker only each 15 or so seconds... Is there any chance that you will update it more often..? You are currently the only exception that publishes old prices. Update per second is industry standard currently. I'm pretty sure that any good IT professional can implement it for you. You can e.g. write the file each second and cache it for 1 second so that any requests in the 1 second time frame gets the cached version. I'm pretty sure it won't impact your server performance.
I'm sure many sites would love it..!
Thank you!

p.s. I know there is websocket version of api, we just prefer the standard https...
