Quote from tradersaavy:
A backtest using YM with the rules for the system as they are but for different years.
Would like to see unfiltered and filtered 1999, 2000, 2001 results, etc.
The YM contract ($5/point) started trading on April 5, 2002. For older data you could try the larger ($10/point) contract (Ticker symbol DJ). However, during RTH, the latter is a pit traded contract.
