The code below demonstrates how to write a simple script that adds new instruments to the instrument data base and application instrument list.

This example can be found in the Script Explorer among other script samples.

Code:
using System;

using OpenQuant.API;
using OpenQuant.API.Indicators;

public class MyScript : Script
{
   public override void Run()
   {
      string[] symbols = new string[] {"Stock1", "Stock2", "Stock3"};
       
      foreach (string symbol in symbols)
         new Instrument(InstrumentType.Stock, symbol);
   }
}

hi! how to add the instruments not to the global instrument list, but to the strategy instrument list? If it is not possible when the strategy is running, how to add the instruments to a strategy BEFORE it is running? Any code snippet available out there??
It can't be true that it might be necessary to add 1000s of symbols/instruments manually to each strategy??????
thanks!

Very good question. I have the same needs.

Hi, I am considering OQ and I would also like to know if the above is possible.

Each OpenQuant project file (i.e. ABCD.oqp) is an XML file so I just generate the instrument symbols to manually add to the file.

This works very well.

Code:
<?xml version="1.0" encoding="utf-16"?>
<!--project file-->
<project schemaVersion="1" name="ABCD" description="" version="1" lang="CSharp">
  <intruments>
    <instrument symbol="A" />
    <instrument symbol="AA" />
    <instrument symbol="AAI" />
    <instrument symbol="AAP" />
    <instrument symbol="AAPL" />
  </intruments>
  <properties>

Where is the "Script Explorer"?
Does he just mean the samples installed with OQ?

Menu View -> Show Script Explorer

The script explorer then appears in the same top right window pane as the solution explorer, but on a different tab.

Thanks.

Any hint how you can add additional parameters to the instrument list, e.g. Exchange or any other property field?

Click on an instrument and edit its properties in the Porperties window?

Now you can use solution scenario to add instruments to solution instrument list programmatically
