## Definition

In the U.S., for the last trading hour on the stock exchange. Experience shows that high-frequency traders, professional traders and large institutional investors condense their business during this period. As a result, there is often a significant increase in volatility in the market at this time (the last hour of exchange trading normally dominated by program traders, large professional traders, and large institutional traders which typically leads to higher-than-average volatility during the last hour of trading). - See computer trading, foreign exchange trading, computerized, flash crash, chime, high frequency trading.
