I was using conductor feed to publish the feed previously however it is not stable at all. Sometimes it works, and sometimes it doesn't. I have to manually run the command, enter password, press Ctrl + Z to stop it, run bg to put it at background and use disown to detach it (stay in background).
During the past few months, I observed that the feed publishing was kinda random sometimes the interval was a few hours, and even worse, it randomly quit.
Recently, I came across the Steem Witness Price Feed Publishing Tool and it works perfect.
Now, 
npm pm2 process management tool, the feed publisher stays controlled in background nicely.
Why Feed Publish?
One of the steem witnesses' responsibility is to publish feed to help build a better steem blockchain.
