Coding for Traders
The C# Fundamentals You Need to Build Indicators and Strategies
Courses
This course is a practical, hands-on introduction to C# built specifically around the TWM platform, so you can start coding your own indicators and systems right away – without getting lost in abstract theory or console apps you’ll never use again.
You’ll start with the absolute basics: what C#, .NET, the CLR and Visual Studio actually are, how they fit together, and how they connect to TWM. Then we’ll walk through setting up Visual Studio, opening a TWM custom project, compiling it, and building your first “Hello World” indicator that prints directly into the TWM Debug window. From the very first lesson, you’re working exactly in the environment you’ll be using later – inside TWM, not in a toy console project.
Description
The core of the course is a series of short, focused videos (each under 10 minutes) where you’ll learn:
- Variables & Data Types
- How to use
int,double,string,bool,enum, and more. We’ll create real examples, show how to initialise them, and explain the difference between global variables and variables inside methods – all with live output in the TWM Debug window. - Methods & Parameters
- How to write simple methods that return values (like
int,double,string) or do work withvoid, pass parameters in, and perform basic calculations (add, subtract, etc.), again seeing results printed in TWM. - Operators & Logic
- How to make your code “think” using
if,else,switch/caseand boolean logic, so your indicators and systems can react to different market situations. - Lists & Arrays
- How to store and manage collections of values using arrays and lists, a foundation for any non-trivial code you’ll write.
- Classes & Structure
- How classes work, how to group logic and data together, and how this maps to the way scripts are structured in TWM.
- Loops (for, foreach, while)
- How to repeat tasks efficiently using different types of loops, a key concept for processing bars, signals or any repeated calculations.
- Dates & Time Handling
- How to work with
DateTimeandTimeSpanto handle timestamps, durations and time-based logic inside your code.
Every video comes with downloadable resources (code snippets, projects, and notes), so you can follow along, copy, modify, and experiment in your own TWM + Visual Studio setup.
By the end of the course, you won’t just “know some C#” – you’ll be comfortable coding directly for TWM, using the Debug window as your main feedback tool and understanding how all the core C# building blocks fit into real-world scripts.
Learn C# Directly Inside TWM
All lessons use real TWM custom projects with Debug window output — no console apps, no theory detours.
Smooth Visual Studio Setup
Step-by-step guidance to install, configure, open, and compile your first TWM indicator.
Fast, Practical Micro-Lessons
Short, focused videos (under 10 minutes) covering variables, methods, logic, loops, classes, and more.
Ready-to-Use Downloadable Code
Every lesson comes with scripts and templates you can plug straight into your TWM workflow.
FAQ
Do you have any more questions about our Extension? Let's see if we already have the answer.
Please read the FAQ below.
Do I need any coding experience before starting this course?
No. The course starts from absolute zero and teaches C# in the context of TWM, step by step.
Will I be using console applications?
No. All examples run directly inside TWM, using the Debug window for output — exactly like real-world development for the platform.
What software do I need to follow the course?
You’ll need Visual Studio and the TWM custom project template. The course shows how to install and set everything up.
How long are the lessons?
Each video is under 10 minutes, designed to be quick, focused, and easy to follow.
Will I get downloadable materials?
Yes. Almost every video includes sample scripts, notes, and ready-to-use indicator templates.
Does the course teach advanced strategy coding?
This course focuses on foundational C# skills in TWM. After finishing it, you’ll be ready to move into advanced system development.
Can I follow the course if I’ve never used Visual Studio?
Yes. The course includes a full Visual Studio setup walkthrough.
Will I learn how to print logs and debug TWM scripts?
Absolutely. Debugging through the TWM Debug window is a core part of every lesson.
Is the content specific to the TWM platform?
Yes. All examples, demonstrations, and code are tailored 100% for TWM scripting.
How quickly can I start writing my own indicators?
After you take 101-102 courses.

James K.
"“Perfect for beginners and traders who want control.” I don’t want to build apps — I just wanted to understand how TWM logic works. This course teaches only what matters, fast."
Alex M.
"“Super clear, super practical.” No fluff. Short videos, straight to the point, and every concept is shown inside TWM. I built my first custom indicator on day one."
Maria L.
"“Made coding feel achievable.” I was scared of Visual Studio, but the setup walkthrough and templates made it simple. Now I can read and write basic TWM scripts with confidence."
Daniel R.
"“Finally a coding course that speaks TWM.” I tried learning C# before but everything was console apps and theory. Here I was printing to the TWM Debug window in the first 10 minutes. Exactly what I needed."
