In the Real-time Market-Data Updates with Elixir article, we have seen how to build a Coinbase WebSocket client and receive real-time trades. In the comments of the article, a reader asked how many trades we receive per second. In general, the rate of trades depends on the product and the time of day. In this article we start to see how to aggregate these trades in real-time, using the GenServer behaviour. We’ll build an aggregation process that groups and count the trades.
