Market Data

Market data is a critical component in trading any financial instruments. In algorithmic trading, data is what an algorithm uses to make buying and selling decisions. And in many cases, that data will consist of stock prices and volumes. There are many variants of market data being distributed, each with its own cost and attributes, and it’s incredibly valuable to understand what market data you are using.
