Answer:the trading and pricing.
Explanation : In 1929, the trading and pricing of stocks was not regulated by the federal government. This was due to the fact that the practice of stock market trading had been largely unregulated prior to the 1929 Stock Market Crash. As a result, investors had little protection from fraudulent or manipulative practices. Additionally, the prices of stocks were determined by the forces of supply and demand rather than any sort of government regulation or oversight.
