Abstract: By analyzing the real-time order flow sent to electronic trading systems such as NASDAQ or individual ECNs and by analyzing the resulting price of the matched execution of buy and sell orders, very accurate lag-free indicators that show the true forces behind the normally considered random intraday price movements of the stock market can be created. These indicators, combined with the stock prices, show how overvalued or undervalued individual stocks or the whole market is compared to what the consensus price should be, based on the actual order flow. This enables traders to take advantage of intraday market price fluctuations of up to 2-4% and, up to hours in advance, to know when a current price move in the market is false and when it is very likely to reverse direction.
