Trading Platform in C# Part 1 - Connect to TWS API

Create a trading platform in C#

Write a Windows form program in C# using Visual Studio and connect to Interactive Brokers Application Program Interface. I prefer writing GUI apps and not console apps. Other things you will need to do is sign up for a trial version of the Interactive Brokers trading software, if you already have an account with Interactive Brokers then great 

 

 

You will need to install 3 different software applications

 

Links to the programs that you need to install

Interactive Brokers Traders Workstation trading platform

Interactive Brokers API 
https://www.interactivebrokers.com/en/index.php?f=5041

Once you have downloaded and installed the above software you are ready to get started

#	Control	Name	Text or Value
1	Button	btnConnect	Connect
2	Combobox	cbSymbol	MSFT
3	Listbox	lbData

Place this on line 19 in the EWrapperImpl.cs file

public Form1 myform;

Place the highlighted text in the tickPrice method within the EWrapperImpl.cs file

public virtual void tickPrice(int tickerId, int field, double price, TickAttrib attribs) 
        {
            Console.WriteLine("Tick Price. Ticker Id:" +tickerId+ ", Field: "+field+", Price: "+price+", CanAutoExecute: "+attribs.CanAutoExecute + 
                ", PastLimit: " + attribs.PastLimit + ", PreOpen: " + attribs.PreOpen);

            string strData = "Tick Price. Ticker Id:" + tickerId + ", Field: " + field +
                      ", Price: " + price + ", CanAutoExecute: " + attribs.CanAutoExecute;

            
            // Add this tick price to the form by calling the AddListBoxItem delegate
            myform.AddListBoxItem(strData);



        }

This is how the Form1.cs file should look.
