Binance order book metrics

[alekseypolukeev]

Overview

There is a working Kotlin application that requests order books for all Binance symbols (financial instruments) and calculates the average volumes for asks and bids, but it does it inefficiently.

The first problem that it takes too long to retrieve order books one by one. Even after the fix, the calculator is not ready to become a real time streaming application as it keeps all the state in memory to compute the average volumes.

We expect the order book metrics calculator to be improved to fit application timeout and reduce memory consumption.
