ATR syntax?

[TTs_MikeC]

Could somebody please help correct me with the proper syntax on this code? If trying to refer to the ATR of a previous hour would it be:

def atr = average(TrueRange(high(period = aggregationPeriod.HOUR),close(period = aggregationPeriod.HOUR),low(period = aggregationPeriod.HOUR))[1],length);

- OR MAYBE -

def atr = average(TrueRange(high(period = aggregationPeriod.HOUR)[1],close(period = aggregationPeriod.HOUR)[1],low(period = aggregationPeriod.HOUR)[1]),length);

Neither throw an error. I was experimenting with adding/subtracting ATR to an average high/low and the plots just don't seem quite right, I suspect something is throwing off the data. I remember reading somewhere that TOS will use highest offset so I'm not sure if my average length being longer than ATR length is effecting it or my syntax

Thanks in advance

Perhaps something like this:

declare lower;

input length = 14;
input averageType = AverageType.WILDERS;
input agg = AggregationPeriod.HOUR;

def h = high(period = agg);
def c = close(period = agg);
def l = low(period = agg);

plot ATR = MovingAverage(averageType, TrueRange(h, c, l), length)[1];

ATR.SetDefaultColor(GetColor(8));

the [1] at the end of the ATR plot line tells ToS to plot the value one bar back.

That may get you going in the right direction at least.
