C20 Monitor

C20 Monitor is a command-line interface app that monitors the C20 Crypto index fund and print out changes to the token value, fund size, and individual stake.

On set intervals, the app will print out the change since the last interval, making it easier to see overall movement.

On exit, the app will print out the changes to the NAV, Fund, and Stake size since the start of the app.

Requirements

1. Node 6+

Usage

1. Clone the git repo
2. Run npm install in the repo folder
3. Run node c20-monitor. This will start the app with default argument values (see below).
4. Exit the app with the ESC key or ctrl + c

Starting with custom values

The monitor takes up to 3 parameters: node c20-monitor [STAKE_SIZE] [UPDATE_INTERVAL_IN_SECONDS] [CHANGE_INTERVAL_IN_SECONDS]

You can also specify specific parameters to set with arguments: node c20-monitor -stake 10000 -time 60 -change 300

Argument	Default	Description
[STAKE_SIZE] or -stake [VALUE]	10000	This is the size of the stake to monitor.
[UPDATE_INTERVAL_IN_SECONDS] or -time [VALUE]	120 seconds	This is C20 token value update frequency in seconds.
[CHANGE_INTERVAL_IN_SECONDS] or -change [VALUE]	3600s (1h)	This is frequency in seconds when to show the changes since start.

Using a config file

Creating a config.json file into the root folder will allow setting these values without having to provide them each time. Example:

{
  "stake": 15000.2501,
  "updateInterval": 120,
  "changeInterval": 3600
}

Stored data

Each time the app refreshes the data from C20 servers, it stores the NAV, C20 Fund size, and a timestamp into a separate data.json file.

Starting the app with this file in the same folder will print out the changes since the last saved state.

Note from dev:

Thanks for the C20 team for delivering an amazing product!
