Abstract
A method of filtering real-time financial data to provide accurate data to users is provided. The method includes comparing the trading price of a currently reported stock trade with the trading price of a previously reported stock trade and identifies the currently reported stock trade as a potential bad trade if the percentage difference between the two is greater than a reference percentage. The real-time spike filter confirms the currently reported stock trade as a bad trade based on: (i) a comparison of the trading prices of the currently reported stock trade and a next reported stock trade; and (ii) a comparison of the trading prices of the previously reported stock trade and the next reported stock trade.
