Hi Graham,
The difficulty when attempting to learn how to program with the object model
documentation is that it presumes the person has certain knowledge and
is really not designed as the first point of reference when your in
the initial learning phase. There are books that focus on this
subject, some very complex and some which present just the necessary basics of OLE
automation.
I have taken your reference to 'time period' to mean 'periodicity', so
the number of quotations will be equal to that set in Database
setting:bars to load.
You can run this as an exploration and then adapt to an indicator as
required. The reference to the Analysis object is only required during
an exploration.
/* Start of exploration code */
AB = CreateStaticObject("Broker.Application");
/* Remove this section for indicator use */
AA = AB.Analysis;
AA.ApplyTo = 0;
AA.RangeMode = 1;
AA.RangeN = 1;
/* Remove above section for indicator use */
Stock = AB.Stocks(Name()); /* Reference to current stock */
Quotations = Stock.Quotations(); /* Reference to the quotations of the current stock */
TotalQuotes = Quotations.Count(); /* Retreive count of the quotations collection */
Filter = 1;
AddColumn( TotalQuotes, "Total Quotes");
/* End of exploration code */
/* Simple indicator code below */
AB = CreateStaticObject("Broker.Application");
Stock = AB.Stocks(Name()); /* Reference to current stock */
Quotations = Stock.Quotations(); /* Reference to the quotations of the current stock */
TotalQuotes = Quotations.Count(); /* Retreive count of the quotations collection */
Title = "" + TotalQuotes;
