What is continuous contract?

Each future instrument has an expiration date and actively traded during a specific period. For example ES has an expiration on 3rd Friday of the contract month. However if somebody is planning to execute simulated trades going over the expiration day a trading strategy should “switch” to the next contract month. But in addition to the expiration day there is a rollover day which occurs on 2nd Thursday of the expiration month for ES future contract. This way a strategy should be configured to switch to the next expiration according to the contract specification or the actual good practice when traders start trading another expiration month. Just using ES as an example, ES 09-14 will be traded the last time on 09/11/2014, however an expiration of that contract is on 09/19/2014. To avoid using an actual contract, there is a special synthetic continuous contract that represents a current front month contract for the future instrument. In NinjaTrader it has a ##-## symbols instead of month and the year. When using a continuous contract a logic of the trading strategy will be simplified and it is not necessary to switch a contract while going over time. This is very important when executing trades over a long period of time using market replay. Our software will automatically prepare a continuous contract for you.
