Hello SnakeEYE,

For something like that I believe you would have to create a custom bar type to be able to control the bar count like that. Creating custom bar types is unfortunately not supported by NinjaTrader. However, you can review source code for existing bar types and could create your own as well. You will need something like Visual studio or a text editor to open this file here:
Documents\NinjaTrader 7\bin\custom\type\@BarTypes.cs

You could also take a look at the source code for indicator HeikenAshi, which is a kind of bar type but developed as indicator. Can view this using Tools > Edit NinjaScript > Indicator > Select HeikenAshi and open.

Otherwise, if you are worried about performance you can always set the Maximum number of bars that your NinjaScript code can look at using the MaximumBarsLookBack.
