The NYSE might have a "historian" on tap! The answers might vary depending on whether we are talking about stock markets, bond markets, commodity trading, etc, etc. It may also vary depending on the rules of the exchange; the NYSE, American Stock Exchange, Philadelphia Stock Exchange, etc, may have or may have had different rules or many different rules at many different times. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
