Patent number: 10891692Abstract: An electronic exchange system network includes a trader site having an automated trading system capable of submitting orders to an exchange site. The automated trading system determines whether an order should be submitted based on, for example, the current market price of an option and theoretical buy and sell prices. The theoretical buy and sell prices are derived from, among other things, the current market price of the security underlying the option. A look-up table stores a range of theoretical buy and sell prices for a given range of current market price of the underlying security. As the price of the underlying security changes, a new theoretical price may be indexed in the look-up table, thereby avoiding calculations that would otherwise slow automated trading decisions. In addition, a system of checks may be conducted to ensure accurate and safe automated trading.Type: GrantFiled: September 23, 2015Date of Patent: January 12, 2021Assignee: DCFB LLCInventors: John M.

Patent number: 10832322Abstract: An electronic exchange system network includes a trader site having an automated trading system capable of submitting orders and/or quotes to an exchange site. The automated trading system determines whether an order or quote should be submitted based on, for example, the current market price of an option and theoretical buy and sell prices. The theoretical buy and sell prices are derived from, among other things, the current market price of the security underlying the option. The theoretical buy and sell prices are calculated when underlying factors that contribute to the theoretical prices change. Computation times of the theoretical prices may be reduced by using precalculated values and/or using interpolation and extrapolation. Other techniques may be used in addition or in the alternative to speed automatic decision-making. In addition, a system of checks may be conducted to ensure accurate and safe automated trading.Type: GrantFiled: November 18, 2013Date of Patent: November 10, 2020Assignee: DCFB LLCInventors: John M.
