Part 1 introduced Cairo's separation between what to draw and where it goes, then implemented the two supporting files: a color type Color.mqh and a surface that binds a pixel buffer to a single chart object Surface.mqh. We finished by writing pixels directly in nested loops and drawing a triangle and a circle with separate functions. more...
In the previous article, From Basic to Intermediate Level: Random Access (II), it was shown how we can work with files while ensuring random access to the data or information they contain. It was also explained and demonstrated that the same concept does not always produce the same result when we looking only at a file’s internal contents. However, when looking at the results displayed in the terminal, there will be no differences between one implementation and another, since the implementation ...
In the previous article I put a small indicator under the MetaEditor profiler and let two columns of numbers tell me where its time was going. The profiler answers one question well: where is this program slow? It has nothing to say about a different and often costlier question, the one where the program is fast enough but simply wrong. A line draws smoothly, the terminal reports no error, and yet the values it plots are quietly incorrect. For that class of problem MetaEditor ships a separate ...
We will look inside the code that transforms a set of neural networks into a thinking, feeling, and evolving trading collective. This is the story of how machine learning has moved beyond simple prediction and entered the realm of creating a digital ecosystem capable of reflection and adaptation. Welcome to the cutting edge of algorithmic trading, where code does not merely execute - it becomes conscious. more...
In this article I build a diagnostic tool—not a strategy—that captures execution metrics on your account. It helps answer one question with numbers: "Is my live result falling short because of the strategy, or because of execution?" The tool is an EA called Execution Quality Monitor. This tool does not measure the broker in isolation. It measures the entire execution path (terminal/PC/VPS, network, broker gateway, venue liquidity), so poor results can come from any link. There ...
