  • Patent number: 8175946
    Abstract: A system, method and computer program product are described for providing the execution probability of a limit order within a given time period based on historical and current information and for adaptively and dynamically adjusting to intra-day trade data. For a given financial interest, the frequency of trade execution, the time evolution of the price, the time evolution of the trade volume, and the current state of the market, among other parameters, are captured and/or calculated. A probability function is generated based on the parameters corresponding to various time spans, and the execution probability of a limit order within a given time period is provided. Embodiments of the invention can be employed to estimate the probability of a limit order being executed within a given time period in the future, e.g., the next two minutes, based on the parameter data of a given time period in the past, e.g., the previous five minutes.

  • Patent number: 7195772
    Abstract: An amino-acid iodine complex, viz. amino-acid amino-carboxyl iodine complex, was provided wherein its coordinate center is iodine molecule, complex reagent is amino-acid, sites of complexing reaction are amino and carboxyl groups of amino-acid. The complex can be used for the production of feedstuff, food additive, disinfectant, antiseptic and medicament. Also provided is a method for the production of said complex comprising opening the inner-complex ring of amino-acid by acid catalysis and allowing the amino-acid to combine with iodine molecule to form an amino-acid amino-carboxyl iodine complex; because amino-acid is a nutriment and amino-carboxyl complex is achieved, their introduction not only increases the nutritional function of the complex and improves the stability of iodine, but also is beneficial to the environment protection and enhances the disinfecting activity against viruses and bacteria.
