A backtest allows you to analyze the historical performance of a strategy. In order to run a backtest you will need:

 

Access to historical data

Custom NinjaScript *strategy

 

Tip:  There are several pre-defined sample strategies that are installed with NinjaTrader that you can explore.

Notes:

1.By default, the Strategy Analyzer downloads data from your market data provider which can slow down backtest progress for larger tests.  If you wish to disable this feature and operate using existing data in your database, right click on the Strategy Analyzer > select Properties > enable Use Local Data Only

2.The IncludeTradeHistoryInBacktest property is set to false by default when a strategy is applied in the Strategy Analyzer for backtesting. This provides for leaner memory usage, but at the expense of not being able to access Trade objects for historical trades. Thus, fields such as SystemPerformance.AllTrades.Count that rely on references to Trade objects will not have any such references to work with. If you would like to save these objects for reference in your code, you can set IncludeTradeHistoryInBacktest to true in the Configure state. For more information, see the Working with Historical Trade Data page.
