The numbers behind this transformation reflect several trends that have reshaped Wall Street over the past decade. Retail trading volumes surged during the pandemic as commission-free brokers attracted millions of new investors, whilst algorithmic trading strategies have become more sophisticated and generate far more order messages even for relatively small position changes.
