Plotting Historical Additional Data Series

[Doctor JR]

I plot the closing values of a couple of additional data series and I use these values in my trading strategy. In real time everything is as should be, but the values lag a full bar (the additional data series bar) in the historical realm. My plot specs are:

xCloses1[0] = Closes[1][1];
zCloses1[0] = Closes[2][1];

The strategy follows from Calculate.OnEachTick. It would seem to me the solution lies in an instruction contained within "if State == State.Historical" but I haven't gotten beyond that. Does a clear fix jump out at you?

Thanks.

I figured it out:

xCloses1[0] = Closes[1][0];
zCloses1[0] = Closes[2][0];

does it correctly in both historical and in realtime.
