Developing a Trading System Based on the Order Book (Part I): Indicator

Developing a Trading System Based on the Order Book (Part I): Indicator

Depth of Market is undoubtedly a very important element for executing fast trades, especially in High Frequency Trading (HFT) algorithms. In this series of articles, we will look at this type of trading events that can be obtained through a broker on many tradable symbols. We will start with an indicator, where you can customize the color palette, position and size of the histogram displayed directly on the chart. We will also look at how to generate BookEvent events to test the indicator under certain conditions. Other possible topics for future articles include how to store price distribution data and how to use it in a strategy tester.

Matrix Factorization: A more practical modeling

Matrix Factorization: A more practical modeling

You might not have noticed that the matrix modeling was a little strange, since only columns were specified, not rows and columns. This looks very strange when reading the code that performs matrix factorizations. If you were expecting to see the rows and columns listed, you might get confused when trying to factorize. Moreover, this matrix modeling method is not the best. This is because when we model matrices in this way, we encounter some limitations that force us to use other methods or functions that would not be necessary if the modeling were done in a more appropriate way.

Self Optimizing Expert Advisor With MQL5 And Python (Part IV): Stacking Models

Self Optimizing Expert Advisor With MQL5 And Python (Part IV): Stacking Models

Today, we will demonstrate how you can build AI-powered trading applications capable of learning from their own mistakes. We will demonstrate a technique known as stacking, whereby we use 2 models to make 1 prediction. The first model is typically a weaker learner, and the second model is typically a more powerful model that learns the residuals of our weaker learner. Our goal is to create an ensemble of models, to hopefully attain higher accuracy.

Building a Candlestick Trend Constraint Model (Part 10): Strategic Golden and Death Cross (EA)

Building a Candlestick Trend Constraint Model (Part 10): Strategic Golden and Death Cross (EA)

Did you know that the Golden Cross and Death Cross strategies, based on moving average crossovers, are some of the most reliable indicators for identifying long-term market trends? A Golden Cross signals a bullish trend when a shorter moving average crosses above a longer one, while a Death Cross indicates a bearish trend when the shorter average moves below. Despite their simplicity and effectiveness, manually applying these strategies often leads to missed opportunities or delayed trades. By automating them within the Trend Constraint EA using MQL5, these strategies can operate independently to handle market reversals efficiently, while constrained strategies align with broader trends. This approach revolutionizes performance by ensuring precise execution and seamless integration of reversal and trend-following systems.
