Accessing price data using BarsInProgress

[pstrusi]

A simple doubt about this specific situation that I'd like to confirm that is what I think by logic.

Let's suppose you Add a new Bar Object to the main instrument, in this example I'm gonna Add the Ask-data through this statement under Initialize () method:

Add(Instrument.FullName, PeriodType.Tick, 150, MarketDataType.Ask);

Each time OnBarUpdate() method is called, the script will detect which one of the Bars Object updated, using the Statement

if (BarsInProgress == 0
{
  // It was main instrument, do your logic
}
else
{
  // It was the Ask-data series, do your logic
}

When the update comes from the Ask-data Bars object( BarsInProgress == 1 ) , then using in the script the following:

1. A Close[0] would be the last ask price t?

2. A Volume[0] would be the last ask volume ?

3. GetCurrentAsk[0] would be the same as Close[0], right ?

Thanks

Hello pstrusi,

Thank you for writing in. You are correct in all but your final statement:

3. GetCurrentAsk[0] would be the same as Close[0], right?

GetCurrentAsk() is not accessed like an array so you use parenthesis and not brackets. The overload you would use is the following:

GetCurrentAsk(int barSeriesIndex)

If you called GetCurrentAsk(1) it would equal Close[0] when BarsInProgress == 1.

Please let me know if I may be of further assistance.

Thanks Michael for the clear answer, it's noted already.
