Coding on 1 min chart and line break

Hi Guys,

I am trying to code my strategy that takes place on a 1 minute chart then add another bar series that states that bars are on the upside of the supertrend on 1, 3 line break.

Here is what I have...

protected override void Initialize()
{

SetProfitTarget(100);

CalculateOnBarClose = true;

AddLineBreak("ES 06-17", PeriodType.Minute, 1, 3, MarketDataType.Last);
}

protected override void OnBarUpdate()
Close[0] > SuperTrend(14, 2.618, true).UpTrend[0])
(How do I code this part to check on the line break chart and not my primary bar series?)

Thanks
