noob error; looking at past bars gives no data

[ssylwester]

why does Close[0] work fine?
but Close[1] returns nothing ?

i have lots of data, i can see that Close[0] is 74.34, and prev close is 74.32

see the bottom of the code snippet

// double average = SMA(VOL(),Period)[0];
double average = Momentum(Close,14)[0]-Momentum(Close,10)[0];
average = Close[0] ; /// this works fine, unless i have the following:
average = Close[1] ; /// this generates NO lines or data
Plot0.Set(average);
}
