building my first strategy

[lightfoot500]

hmm, can that be done from the strategy wizard?
so what if i added something like,
bbdifference = (Bollinger(2, 20).Upper[3])-(Bollinger(2,20).Upper[0]) or something like that so i can get the difference between current bb value and a value n bars back?

lightfoot500, unfortunately you would need to code an indicator for the difference in the NinjaScript editor and then use this in your Wizard strategy.
