Strategy Analysis Optimization - Trade selection

[Sweet&Sour]

Hi

I wonder how can i get the trades listed under Display: Trades($) in Strategy Analyzer during Optimization?

While in State.Terminated, if i run through the SystemPerformance.AllTrades collection, i'll get a bulk of trades but most of them are just duplicates. I would be interested into these trades which the Strategy Analyzer has preferably selected to show me in the Dispay tab.

Thanks...

Hello Sweet&Sour,
Thanks for your post.

There is no supported way of doing this. You would need to process that information in the strategy itself.

While in State.Terminated

Why have you chosen to use State.Terminated? The script is being destroyed at that point and alot of information would be unavailable anyway

If i run through the SystemPerformance.AllTrades collection, i'll get a bulk of trades but most of them are just duplicates.

There should be no duplicates in that collection. How are you confirming that there are duplicates? Can you run script at the following link? This script would not be able to run if there were duplicates present.

Hi Josh,

Where's the best place within the code to enumerate all trades from the SystemPerformance.Trades collection?

Here's the code snippet:
if (SystemPerformance.AllTrades.Count > 1)
{
foreach (Trade myTrade in SystemPerformance.AllTrades)
{
using (StreamWriter outputFile = new StreamWriter(path, true))
{
string[] lines = System.Text.RegularExpressions.Regex.Split(myTrade .ToString(), " ");

string fileOutput = string.Empty;
foreach (var line in lines)
{
fileOutput = fileOutput + "|" + line.Split('=').Last().Replace("'", "");
}
fileOutput = fileOutput.Substring(1);
outputFile.WriteLine(fileOutput);
}
}
}

There should be no duplicates in that collection. How are you confirming that there are duplicates? Can you run script at the following link? This script would not be able to run if there were duplicates present.

I wouldn't recommend OnStateChange() since we want to keep that as lean as possible. Why not to do it inside OnBarUpdate() ?
