A programmable trading system for explicitly and or automatically inputting a number of trading orders, such as offers to buy and sell shares of stocks or other types of offers, such that some or all of the trading orders are executed in a particular sequence based on specified criteria and provide the ability to investors to place multiple trading orders from a single order input which provides transaction pattern information of the trading orders. While each programmed transaction is being completed the other transactions are temporarily blocked until another of the orders in the sequence can be transacted based on the given programmed criteria. The system may comprise multiple layers of trading sequences including a number of programmable groups, each of the groups having a number of transactions.
