Backtesting Error

[Sandra73]

Hello, I'm running my strategy on backtesting but I'm getting the following error : " Object reference not set to an instance of an object ". this error its only happening on backtesting, in Realtime it works perfect. The code is not entering the loop when it does the backtest, idk why.
Attached the code lines waiting for help thanks

Hello Sandra73,

DrawingObjects are not drawn during a backtest.

The ChartControl will be null until after the backtest is complete.

You can check the ChartControl is not null, the DrawObjects collection is not null, the variable myReg_reingreso is not null, etc.

Unfortunately, I don't have a link for a note on this in NinjaTrader 7, but I can provide a link to the help guide on DrawObjects.

Hello ChelseaB;
I have no idea how I can fix this. I use Region EndAnchor.Price as a re-entry price level? But Draw Collection is null on backtesting, any way to draw object or access the levels of the region(Start/EndAnchor) to take them as a reference?
I'm using NT8
Thanks

Hello Sandra73,

Don't use drawing objects for prices in a strategy that is meant to be back-tested.

Just calculate the prices directly, and use these for the order prices.

You will not be able to use drawing objects in a backtest.
