You can Playback either Market Replay data or historical tick data. For the most accurate reflection of live market conditions you would want to use Market Replay data.

 

Notes:

1.Market Replay data holds the exact sequence level I and Level II (market depth) data and must be recorded or downloaded by NinjaTrader.  

2.Alternatively, historical tick data can be used to playback chart data (without market depth). The granularity and accuracy of historical mode will be dependent on your data provider.

3.The Playback101 account properties (e.g., Commissions, Risk, etc.) are created from the Sim101 account when connecting to the Playback Connection and cannot be reset while connected. The Playback101 account will reset with current Sim101 account properties when reconnecting.

4.TimeInForce logic such as order expiration / cancellation at the end of a session, is not supported for the Sim101 or Playback101 accounts.

5.It is recommended to close and save your live workspaces then use dedicated workspaces for Playback before connecting to Playback to ensure items, such as drawing objects, are not affected in your live workspaces.

If Market Replay data is not available, or you do not need the accuracy that Market Replay data provides, you can optionally use playback using historical tick data offered from your data provider. You can download, export, import historical tick data via the Historical Data Window.

Recording Data

Once Enable market recording for playback is enabled (see the "How to enable the market replay recorder" section above), data is recorded for any instrument in any NinjaTrader window that is receiving live market data. Level II (market depth) data is only recorded if a Level II, SuperDOM, or FX Pro window is open and receiving data for the instrument. The Market Analyzer window is the recommended recording window as multiple instruments can be added to one Market Analyzer window and all recorded at the same time.
