Hi,
I am workinig on a code that does some initial stock filtering wthin the Initialize function by triggering an standalone class. I am unable to find a way to:
1. Run debug messages from the code. ( I was able to retrieve variables from the class so I know it was created, but the constructor debug message was never triggered)
2. Get histroical prices within the partial class function. Is this not possible within QC or am I doing it in the wrong way?
Very thankful if anyone has some inputs.
namespace QuantConnect {
public partial class PairSelection : QCAlgorithm, IAlgorithm
{
private string[] tickerSymbols;
public PairSelection(string[] tickers){
this.tickerSymbols = tickers;
Debug("Triggered the PairSelection constructor");
}
public List<Stocks> selectPairs()
{
Debug("Triggered the selectPairs function");
for(int m = 0; m<tickerSymbols.GetLength(); m++){
AddEquity(tickerSymbols[m], Resolution.Daily);
var histEq = History(tickerSymbols[m], TimeSpan.FromDays(252), Resolution.Daily);
// Do some other things
}
}
}
}

Have you tried passing the QCAlgorithm as argument?
Something like:
public class CoolAlgorithm : QCAlgorithm { public override void Initialize() { SetStartDate(2013, 10, 07); //Set Start Date SetEndDate(2013, 10, 11); //Set End Date SetCash(100000); } public override void OnData(Slice data) { MyStaticClass.MyStaticMethod(this); } } public static class MyStaticClass { public static void MyStaticMethod(QCAlgorithm algorithm, Slice data) { // Do your magic here } }Jan Sedlak
I tried paste the class direcly in the Intialize function and then the debug and data function works. I can try this option as well. Would you trigger the debug funtion by calling algorithm.Debug("Debug message")?

Yes, and you'll also have access to all the algorithms objects like Portfolio, Securities, Transactions, etc!Jan Sedlak
Sounds good. Thanks for the tip!
