Randy,
As far as I'm aware, IB does not have a continuous contract for the YM. IB only supports 30 days of backfill for a specific contract. They do not do any back-adjusted of prices like eSignal and TradeStation to create a continuous contract. I use the individual contracts collected from IB in 3 month chunks for intraday YM backtesting. If you want years of historical data, you can obtain it from www.scmagic.org/English/Index.htm.

My question is if there is a continuous contract symbol available. That allows data to be accumulated without regard to contract expiration. Randy
