dataseries on multi time frame strategy

[stevescott05]

Simple question, created a dataseries 'swingLows' in a strategy being run on a 2min chart. The strategy adds a tick series as well.

How many values will swingLows contain? As many as the primary series?

So, if a portion of the code says something like:

if (BarsInProgress == 0)
{
    if (Lows[0][3] >= Lows[0][2] && Lows[0][2] <  Lows[0][1])
    {
          swingLows.Set(Lows[0][2];
     }
}

if (BarsInProgress == 1) //referring to the added tick series
{
    for (int i = 0; i < swingLows.Count; i++) 
    {
         if (Opens[1][1] >  swingLows[i] && Opens[1][0] <= swingLows[i])
         {
            .....
          }
     }
}

Can I feel confident that swingLows[3], no matter what BarsInProgress section it's being referred to in, will always be referring to the 3rd bar ago on the 2 min chart?

Thanks

BarsInProgress only checks which Bar object is calling OnBarUpdate. This means that regardless of where you have called swingLows[3], it will be referring the primary series you had Set() in the data series.

Okay, so if there are only 10 bars on the primary (2 min) chart, and I only use swingLows.Set() in a BarsInProgress == 0 area of the code, then there will only be 10 values in the swingLows DataSeries... have I got it right?

Yes, if you're counting from the current bar on the chart.

If you were counting from Lows[0][2], there would only be 8 out of 10 bars in the series.
