System and method for simultaneous trading of options

摘要

A method and system for facilitating trading of equity and index options is provided. The system incentivizes market makers to voluntarily agree to restrict the bid/offer spread on price quotes for options by enabling the market makers to submit batches of bids and offers simultaneously. The system also provides protection to the market makers by enabling withdrawal of certain bids and offers if a cumulative delta on traded options has been exceeded. The system also provides limits on the rates at which individual traders and the overall market submit bids and offers. The system provides summarization of market data to enable market makers to have relevant and timely data at all stages. In this manner, the system achieves increased liquidity of the equity and index options markets.
