I'm trying to create a custom indicator in NinjaTrader but I'm running into a very odd problem. In the .onBarUpdate() method it won't let me have ANYTHING in the function and the only variable it wont display any Close[x] value if its greater than 0. If i put anything in the function ex: protected override void OnBarUpdate() { double x = Close[1]; GRPlot.Set( Close[0] ); } In my indicator window this won't display anything, neither will this: protected override void OnBarUpdate() { GRPlot.Set( Open[1] ); } It appears that it's having a serious problem getting any information past the reference point of '0'. Anyone got any advice?
