Help going through old charts

[wandering_dreamer]

Can anyone help me? I'm trying to do some back-testing however I can't remember how to link the contracts so I can go through a previous months (eg oil June 2013).

Thank you for reading.

Hello wandering_dreamer,

Thank you for your post.

Using the current contract and the MergePolicy of either MergeBackAdjusted or MergeNonBackAdjusted will allow you to backtest through the previous contracts. For information on the Merge Policies please visit the following link: http://www.ninjatrader.com/support/h...rical_data.htm
