A system for correctly evaluating a price distribution and a risk distribution for a financial product or its derivatives introduces a probability density function generated with a Boltzmann model at a higher accuracy than the Gaussian distribution for a probability density. The system has an initial value setup unit and an evaluation condition setup unit. Initial values include at least one of price, price change rate, and the price change direction of a financial product. The evaluation conditions include at least time steps and the number of trials. The Boltzmann model analysis unit receives the initial values and the evaluation conditions, and repeats simulations of price fluctuation, based on the Boltzmann model using a Monte Carlo method. A velocity / direction distribution setup unit supplies the probability distributions of the price, price change rate, and the price change direction for the financial product to the Boltzmann model analysis unit. A random number generator for a Monte Carlo method employed in the analysis by the Boltzmann model, and an output unit displays the analysis result. A dealing system applies the financial Boltzmann model to option pricing, and reproduces the characteristics of Leptokurcity and Fat-tail by linear Boltzmann equation in order to define risk-neutral and unique probability measures. Consequently, option prices can be evaluated in a risk-neutral and unique manner, taking into account Leptokurcity and Fat-tail of a price change distribution.

A system and method for predicting price fluctuations in financial markets. Our approach utilizes both market history and public news articles, published before the beginning of trading each day, to produce a set of recommended investment actions. We empirically show that these markets are surprisingly predictable, even by purely market-historical techniques. Furthermore, analyzing relevant news articles captures information features independent of the markets history, and combining the two methods significantly improves results. Capturing usable features from news articles requires some linguistic sophistication the standard naïve bag-f-words approach does not yield predictive features. Instead, we use part-of-speech tagging, dependency parsing and semantic role labeling to generate features that improve system accuracy. We evaluate our system on eight political prediction markets from 2004 and show that we can make effective investment decisions based on our systems predictions, whose profits greatly exceed those generated by a baseline system.

An improved method and system for computerized trading of securities in which order preferences for securities are entered by a user and are stored on a computer system for future use as default values in response to the user placing an order. The time that it takes to complete an order may be reduced through the use of previously selected order preferences being displayed to the user in the order placement window. In another method for order entry, a user may specify a price-point and a security transaction flag option for a security transaction (e.g., buy, sell, sell short, stop loss, stop limit, sell to open, sell to close, buy to open, buy to close) on a price chart window for a particular security. The computer system monitors the price fluctuation of the particular security, and takes the specified security transaction in response to the specified price-point being reached. In another embodiment, real-time results for user-selected studies are utilized as a tool for a user to decide on a price-point at which to take a particular security transaction on a particular security.

A system mitigates the effects of a market spike caused by the triggering and election of conditional orders in an automated matching system. The system monitors trading that takes place as a result of the cascading triggering of conditional orders. When an order is executed beyond a predetermined price threshold, an instrument may be flagged, allowing matching to take place only at or within the predetermined price threshold. Orders within the price threshold are matched at the price threshold against orders beyond the price threshold, in order to dampen any instantaneous damaging effects of the price spike. The system may adjust the price threshold when market appropriate, allowing the order flow to bring the market back to whatever is the true price level. The system mitigates price fluctuations that are purely conditional order cascade driven, but allows the market to continuously trade in controlled price and time intervals to ensure that a true market move can still occur and not have price control mechanisms hinder trade matching and true price discovery.

A method of creating a price prediction model that forecasts short-term price fluctuations in financial instruments by collecting, analyzing and classifying financial news for a financial instrument into categories. Distributions for the changes in price of the financial instrument for a set period of time and distributions for the changes in price of the financial instrument as a result of the financial news for each news category for a set period of time are then obtained. If the distributions for the changes in price of the financial instrument are statistically significantly different than the distributions for the changes in price of the financial instrument for a particular news category, and the mean for the change in price is greater or less than zero, a signal is produced indicating the trading action that should be taken for the financial instrument.

This invention has the potential to generate very good return on investments from stocks that are conservative in movement. This invention will greatly benefit investors that do not have the time to constantly trade stock yet want to take advantage of normal price fluctuations. The Limit Order Coupled LinK (LOCK) invention, for example, will take a buy order, complete the transaction at the specified price, then automatically resubmits a new order to sell at a specified higher price. If specified, the process can automatically cycle through the buy-sell process a set number of time allowing the investor to take advantage of intra-day market moves and normal stock price fluctuations with no personal investor evolvement. The LOCK order, with set profit margins, allows on-line traders and brokers to place one order, which will automatically generate logical, sequenced additional orders returning a profit on each transaction. LOCK will benefit both the investor and the stock trading company.
