Creating new broker in Tradelink

I'm trying to refactor the Tradelink code to add a new Broker. I just want to implement a price server for the moment. I don't want position management or accounts or anything: I just want Quotopia to display whatever ticks I send to it from the new server.

I can get Quotopia to recognize that the server is running, but can't fire the _bf.gotTick() method in Quotopia. What am I doing wrong?

using System;
using System.Collections.Generic;
using System.Threading;
using System.Windows.Forms;
using TradeLink.API;
using TradeLink.AppKit;
using TradeLink.Common;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
TestServer server = new TestServer();
}
}

class TestServer
{
public const string PROGRAM = "TestServer";
Log _log = new Log(PROGRAM);
TradeLink.API.TLServer tls;
public TestServer()
{
tls = new TradeLink.Common.TLServer_WM();
tls.newProviderName = Providers.Unknown;
tls.newRegisterSymbols += new SymbolRegisterDel(tl_newRegisterSymbols);
tls.VerboseDebugging = true;
}

public void Start()
{

while (true)
{
System.Diagnostics.Debug.WriteLine("Sending tick!");
Tick t = new TickImpl();
t.date = Util.ToTLDate(DateTime.Now);
t.time = Util.DT2FT(DateTime.Now);
t.symbol = "GOOG";
t.bid = Convert.ToDecimal(101.00);
t.ask = Convert.ToDecimal(102.00);
t.ex = "none";
tls.newTick(t);
System.Threading.Thread.Sleep(2000);
}
}

private void tl_newRegisterSymbols(string client, string symbols)
{
System.Diagnostics.Debug.WriteLine("tl_newRegisterSymbols");
var t = new Thread(() => Start());
}
}
}

 

lol. good luck.

 

Thanks for that. Can you recommend a different trading platform that doesn't use a proprietary language?

 

Which TradeLink code base are you starting with?

I suggest you start here https://bitbucket.org/JDFagan/tradelink/src

 

I can't help with your specific question but one caution: The public contribution has all but vanished for the Tradelink project. The only ones left contributing are those affiliated with a for profit venture and hence closed code base. They infrequently contribute to the open source code base but the project progress in open source space has all but fallen off a cliff. I won't get into why this has happened I just state the fact.

 

I see there's a paid component to it now, hence the difference branches available. Is there any other platform worth looking at? I have to write the price feed and OMS for this app myself anyway: was just wondering if I could find a package with a dashboard I could re-use (quoteboards, charts etc).

 

There are but if you are targeting .Net then this is pretty much it in open source space.

 

Thanks for that. What about Java? C++ is out for the moment.
