Reflecting upon the previous discourse "Developing a Replay System — Market simulation (Part 01): First experiments (I)", the concept of creating an event system for generating an adequate market simulation presented certain limitations. Notably, the 10-millisecond mark seemed unreachable, significantly impacting the system's effectiveness. Studying the related attachments elucidates this point, revealing that even the 10-millisecond range might not be sufficient.

Efforts to attain a 1- or 2-millisecond execution timeframe confronted inherent operational barriers. The operating system's timer is incapable of reaching these values, thereby creating a significant impediment. Despite this, the existing system still affords a number of computational possibilities that can be exploited.

Attempting to attribute the failure to reach the 1-minute mark to modern processor limitations reveal...

The contemporary library presented allows an effortless interface with PNG graphic files and provides options for scaling them. PNG images can be uploaded in two ways: either via direct file upload or sourced from within an ex5 file.

When working with PNG images via resources, an immediate canvas can be formed and the images can be directly screened. Alternatively, the creation of a bmp[] bitmap array, discarding the step to create a canvas object for the image, can also be pursued. The bmp[] array can find pulse in more advanced implementations with proprietary canvases.

An imperative feature of the CPng class is the Resize(double NewWidth) method. It fosters the generation of new image sizes within the _bmp[] array, which can be screened by forming the canvas of corresponding size. The class instance will thus carry two bmp[] arrays (original size) with width "width" and height "h...

Unveiling a technical strategy that employs a combination of indicators and tools to generate trading signals and targets. Noteworthy components include a 14-period stochastic oscillator, a 5-period stochastic oscillator, a 200-period moving average, and a Fibonacci projection tool. The stochastic oscillator, developed by George C. Lane, calculates a financial instrument's price momentum and strength. Amid trading, if the stochastic oscillator verges on the lower boundary, it indicates oversold levels and a bullish bias. Conversely, nearing the upper boundary flags overbought levels and a bearish bias.

Meanwhile, with the moving average technique, data is smoothed over a particular period to identify trends and formulate trading signals. This method calculates by averaging a given set of prices over a specific time, then updates as new data becomes available. Older data points are s...

Understanding the dynamic nuances of trading strategies is elemental. Highlighted here is a contrast between the wide-known Trailing Stop and the recently presented Trailing Take Profit. The former tracks price fluctuations until the stop loss hits, rendering the position closed profitably. The latter, instead, trails the price when a position is incurring loss, leading ultimately to the position's closure at a loss.

Consider a scenario: A position is sinking into losses when the current price reaches the TrailingTPStart. For example, if the TrailingTPStart is 500 points, the price reaches 500 points from the opening price, and the position is at a downward spiral of -500 points, this is where Take profit begins its trail. The TrailingTPDistance canvasses for the largest distance between the trailing take profit and the current price.

While this concept's utility may vary, it coul...
