When there is a sudden market collapse and when we need to respond immediately rather than waiting for human intervention, programs takes control of trading in the exchanges. Algorithms can be implemented for liquidation or intraday market speculation or arbitrage trading or depends upon the business need. Programs need to make the correct judgment by watching the real time market data. The programs need to identify the market trend, technical support, trading unusual volume, etc.
