Exchange Subscriptions
Exchange Subscriptions are streams of data delivered via websocket.
GoCryptoTrader engine will subscribe automatically to configured channels. A subset of exchanges currently support user configured channels, with the remaining using hardcoded defaults. See configuration Features.Subscriptions for whether an exchange is configurable.
Templating
Exchange Contributors should implement GetSubscriptionTemplate to return a text/template Template.
Exchanges are free to implement template caching, a map or a mono-template, inline or file templates.
The template is provided with a single context structure:
S *subscription.Subscription
AssetPairs map[asset.Item]currency.Pairs
AssetSeparator string
PairSeparator string
BatchSize string
Subscriptions may fan out many channels for assets and pairs, to support exchanges which require individual subscriptions.
To allow the template to communicate how to handle its output it should use the provided directives:
- AssetSeparator should be added at the end of each section related to assets
- PairSeparator should be added at the end of each pair
- BatchSize should be added with a number directly before AssetSeparator to indicate pairs have been batched
Example:
{{- range $asset, $pairs := $.AssetPairs }}
{{- range $b := batch $pairs 30 -}}
{{- $.S.Channel -}} : {{- $b.Join -}}
{{ $.PairSeparator }}
{{- end -}}
{{- $.BatchSize -}} 30
{{- $.AssetSeparator }}
{{- end }}
Assets and pairs should be output in the sequence in AssetPairs since text/template range function uses an sorted order for map keys.
Template functions may modify AssetPairs to update the subscription's pairs, e.g. Filtering out margin pairs already in spot subscription.
We use separators like this because it allows mono-templates to decide at runtime whether to fan out.
See exchanges/subscription/testdata/subscriptions.tmpl for an example mono-template showcasing various features.
Templates do not need to worry about joining around separators; Trailing separators will be stripped automatically.
Template functions should panic to handle errors. They are caught by text/template and turned into errors for use in subscription.expandTemplate.
