<p>It is not common to have Push APIs for Exchange sites. However Poloniex has WAMP (Web Application Messaging Protocol) over WebSocket for ticker:</p>

<p>Does any exchange provide API to call callback function on each transaction?</p>

<p>I would like to build a auto trade platform based on the tick event, but instead of pulling the price, I would like to use the push mechanism.</p>
