License

Installation

Install the latest version of the ig_markets gem with the following command:

$ gem install ig_markets

Usage — Command-Line Client

The general form for invoking the command-line client is:

$ ig_markets COMMAND [SUBCOMMAND] --username USERNAME --password PASSWORD --api-key API-KEY [--demo] [...]

Config File

On startup ig_markets looks for config files at ./.ig_markets.yml and ~/.ig_markets.yml. These are YAML files that can hold named sets of predefined authentication profiles in order to avoid having to specify these repeatedly on the command-line for every invocation.

The desired authentication profile is specified using the --profile command-line argument, and if the --profile argument is omitted then the default profile will be used.

Here is an example of a config file with a default profile and a demo profile:

profiles:
  default:
    username: USERNAME
    password: PASSWORD
    api-key: API-KEY

  demo:
    username: DEMO-USERNAME
    password: DEMO-PASSWORD
    api-key: DEMO-API-KEY
    demo: true

The following examples assume the presence of a config file that contains a valid default authentication profile.
