Summary

A custom component to display stock information from Yahoo finance.

Installation

This can be installed through HACS or by copying all the files from custom_components/yahoofinance/ to <config directory>/custom_components/yahoofinance/.

Configuration

Define the symbols to be tracked and optional parameters in configuration.yaml.

# Example configuration.yaml entry
yahoofinance:
  symbols:
    - ISTNX

The above configuration will generate an entity with the id yahoofinance.istnx and current value as the state along with these attributes:

Optional Configuration

• Data fetch interval can be adjusted by specifying the scan_interval setting whose default value is 6 hours and the minimum value is 30 seconds.

  scan_interval:
    hours: 4

  You can disable automatic update by passing None for scan_interval.

• Trending icons (trending-up, trending-down or trending-neutral) can be displayed instead of currency based icon by specifying show_trending_icon.

  show_trending_icon: true

• All numeric values are by default rounded to 2 places of decimal. This can be adjusted by the decimal_places setting. A value of 0 will return in integer values and -1 will suppress rounding.

  decimal_places: 3

• An alternate target currency can be specified for a symbol using the extended declaration format. Here, the symbol EMIM.L is reported in USD but will be presented in EUR. The conversion would be based on the value of the symbol USDEUR=X.

  symbols:
    - symbol: EMIM.L
      target_currency: EUR

  If data for the target currency is not found, then the display will remain in original currency. The conversion is only applied on the attributes representing prices.

Examples

• The symbol can also represent a financial index such as this.

  symbols:
    - ^SSMI

• Yahoo also provides currency conversion as a symbol.

  symbols:
    - GBPUSD=X

• The trending icons themselves cannot be colored but colors can be added using browser_mod. Here auto-entities is being used to simplify the code.

  - type: custom:auto-entities
    card:
      type: entities
      title: Financial
    filter:
      include:
        - group: group.stocks
          options:
            entity: this.entity_id
            style: |
              :host {
                --paper-item-icon-color: {% set value=state_attr(config.entity,"trending") %}
                                        {% if value=="up" -%} green
                                        {% elif value=="down" -%} red
                                        {% else %} var(--paper-item-icon-color))
                                        {% endif %};

Services

The component exposes the service yahoofinance.refresh_symbols which can be used to refresh all the data.

Breaking Changes

• As of version 1.0.0, all the configuration is now under yahoofinance. If you are upgrading from an older version, then you would need to adjust the configuration.
