Setup your Ubuntu server:,24005.0.html

Setup your bitShares node:,23925.0.html

I did some testing, reading and browsing through different price feed scripts and ended up picking wackou's BTS Tools.
Here are some of the options:

And wackou's BTS Tools:

You will need to create an api access file for BTS Tools to interact with your node so let's start with that:

SSH to your server
You will need to get a hash for your witness' password:
Code: [Select]
$ python bitshares-core/programs/witness_node/
enter your password (for example: supersecret) and you will get your hash & salt, like so:
            "password_hash_b64" : "9e9GF7ooXVb9k4BoSfNIPTelXeGOZ5DrgOYMj94elaY=",
            "password_salt_b64" : "INDdM6iCi/8="

Now move back to the directory where you want your api access file to be at, for example your home directory:
Code: [Select]
Create your api access file:
Code: [Select]
$nano api_access.jsonEnter:
   "permission_map" :
            "password_hash_b64" : "9e9GF7ooXVb9k4BoSfNIPTelXeGOZ5DrgOYMj94elaY=",
            "password_salt_b64" : "INDdM6iCi/8=",
            "allowed_apis" : ["database_api", "network_broadcast_api", "history_api", "network_node_api"]

Save & Exit.

Edit the node config file and add the location for your api access file:
Code: [Select]
$nano bitshares-core/witness_node_data_dir/config.ini
api-access =
and modify:
api-access = /home/muLinuxUser/api_access.json

Save & exit

Installing BTS Tools:
Install dependencies:
Code: [Select]
$sudo apt-get install build-essential libyaml-dev python3-dev python3-pip
Install tools:
Code: [Select]
$ pip3 install bts_tools
Verify installed version: (it should also create a default config.yaml file for you):
Code: [Select]
$bts - version
Edit your config.yaml file:
Code: [Select]
$nano .bts_tools/config.yaml# For a more detailed description of the format of this file, visit:

Save & exit
For production deployments, it is recommended to put it behind a WSGI server, in which case the entry point is bts_tools.wsgi:application
You can set it up according to wackou's docs:

Start your witness node,
Start CLI, unlock it and import feed key for BTS Tools:
Code: [Select]
import_key "announce" 5KJJNfiSyzsbHoVb81WkHHjaX2vZVQ1Fqq5wE5ro8HWXe6qNFyQ
verify your signing key and witness info:
Code: [Select]
run the BTS Tools monitor:
Code: [Select]
$bts monitor
and you are all set!

To update your BTS Tools to a new version:
Stop the monitor (CTRL-C) and upgrade:
Code: [Select]
$pip3 install --upgrade bts_tools
Edit config.yaml and adjust as required

Restart the monitor:
Code: [Select]
$bts monitor
