Get and keep an advantage on the market

Congratulations! You have just committed yourself to one of the most challenging exercises today. Algorithmic trading is a fascinating world. Its learning will allow you to push the boundaries of technical analysis and trading.

I wrote this book to help you design your trading system using Prorealtime. As a first step, I give you a theoretical and conceptual basis needed to develop trading algorithms. Then, step by step, I will lead you in the programming of your trading bot. After that, a chapter about the backtest analysis will explain how to reduce the risk of over-fitting.

I created a machine learning model specially adapted to optimize the automated trading systems that you will easily use to configure your trader robot.

After running on a real account, you will have to manage your automated trading systems. There are some management rules that you need to know and strictly apply. These rules will allow you to know when to start and stop a trading system.


Thanks to this book, you give yourself the means to create a robust and reliable automated trading system.

What about the news?


1. How to choose the best technical indicator?

I will give you a source code that calculates the correlation between two technical indicators. That will help you better choose your indicators for manual trading as automated trading. Using uncorrelated indicators improves the market reading and the decision-making.


2. Find the best moving average crossing

You will find the best profitable moving average crossing thanks to an algorithm built on the arrangements without repetition. The source code is easy to use, and it can be applied to any trend indicator.


3. Chartist figure recognition

I completely rewrote this chapter. I provide you with three algorithms capable of recognizing any chartist figures, from the simplest to the most complex. The first algorithm works with correlation, the second with Euclidian distances, and the third with Hausdorff distance. Mathematic distances are particularly efficient with chap recognition. The source codes are detailed and explained. You simply have to put your preferred figure in the dataset to create your chartist indicator.


4. Multi-timeframe fractal arbitrage

It is a new chapter in which I introduce an arbitrage between two timeframes. The algorithm calls the multi-timeframe fractal correlations to anticipate a bullish reversal. This strategy works on most of the main indexes like the S&P500, the Dow Jones, or the Dax40.


5. Voluntary under-optimization model

This model is straightforward to understand and use. It consists of voluntary degrading the performance of a backtest to increase the probability of gains in the future.


6. Overfitted strategy arbitrage

It is the opposite of the previous model. An over-optimized strategy has more chance of losing in the future than winning. This model tries to turn the risk of loss into an expected gain. It consists of voluntarily over-optimizing a strategy to open reversal entry in the future. However, you will need to respect some rules to apply this model.

    The prorealtime programming guide doesn’t explain in detail how the code works. This book fill in some gaps and has quite a few examples and ideas. It has paid for itself quickly just on use of the ‘QUIT’ instruction alone. I am finding it very helpful.

    This book is impressive: it combines multiple disciplines such software engineering, math, trading of course…
    it is very clear with simple to understand. Congratulations to the author!

    This book is a goldmine for developers of automated trading systems, not only for those who are using Pro Real Time. I have been developing automated systems now for a year, and this book gave me the confirmation that I am on the right way. Several of the concepts that I implemented, are also proposed in this book. Furthermore it provided me with many new ideas and improvements for my systems. Especially a lot of attention is given to risk management, backtesting and how to avoid the pitfall of over optimizing your systems (curve fitting). Furthermore the questions I had where promptly answered by the author.

    I definitely recommend this book.
