Volume Spread Analysis (VSA)

Volume Spread Analysis (VSA) is a method of analyzing the stock market that uses volume, price, and spread data to identify buying and selling pressure. Developed by Tom Williams, a trader, and author, VSA is based on the idea that the market is driven by the actions of professional traders, also known as “smart money.” These traders use volume, price, and spread to conceal their actions and intentions, but VSA can help to uncover them.
