Students at the Bronx School of Law and Finance won't need to call a stock broker to make their latest Wall Street trades. Thursday was the ribbon cutting for a virtual stock exchange at the school that will let the students buy and sell stocks on an actual trading floor. The student traders have constant access to financial news on television and a stock ticker. They even get to wear similar jackets to actual traders. The curricula was created by the National Academy Foundation. School officials said the stock exchange is the first of its kind in the entire country.
