BarsInProgress

[blar58]

I would like to know what happens when an indicator is derived from another indicator which has many Time Series.

Example :

Indicator1 : Indicator
Indicator 2 : Indicator1

Indicator1 has 2 BarsArray (ProgressBar == 1 1 tick and ProgressBar ==0 30 minutes)
Do I have to Add 1 tick period to Indicator2 if I don't need it...


Thanks

Hi blar58,

Values generated from other series are available without having to add the series. The series, themselves are not available from the calling indicator unless you add them.

Example.
Indicator 1 calls Indicator 2

Indicator 2 has added series and plots a value based on these added series. You can access the value of this plot from indicator 1, but not the series unless you add it.

Here is my situation :

Indicator1 : Indicator

Initialize()
Add(PeriodType.Tick,1);

OnBarUpdate()
     if(BarsInProgress ==1)
      indicator2OnMarketData(volume)


Indicator2 : Indicator1
Initialize()
.....

indicator2OnMarketData(volume)
// do stuff

Tick dataseries has been added to Indicator 1 only. When I called BarsInProgress == 1
and I called a method that belongs to indicator 2 which has only the primary bar series
does the indicator2OnMarketData(volume) method is being executed with tick data series ?

Thanks

Indicator 2 offers only the BIP that the series is applied to, since no other series has been added. You can access values generated from Indicator 1, even if the values are based on another series.

If you need to do calculations on other series within indicator 2 then all these series must be added.

Attached are two scripts that illustrate this. Indicator 2 is getting a value that is derived from the added series in indicator 1. This is available, but the series itself is not available unless you add it.
