The ElectroMagnetism-like (EM) algorithm, a metaheuristic search algorithm, simulates the behaviour of electromagnetic particles to solve non-linear optimization problems. Guided by electromagnetism theory, EM uses attraction-repulsion mechanisms to attain global optimal solutions. The algorithm primarily involves forming solution populations, calculating electromagnetic forces between solutions, updating solution populations, and establishing stop conditions. Despite its potential, EM showed subpar performance in tests but outperformed some powerful algorithms on the Rastrigin function test with 1000 parameters.

Revisiting the previous focus on Decision Transformer methods and autoregressive models, the performance of the model tends to decrease following initial profitability. This drawback could potentially be mitigated through periodic additional training; however, this inherently complex method would benefit from online model training.

February 2022 saw the introduction of the Online Decision Transformer, a derivative of the classic Decision Transformer. Noteworthy is the fact that the ODT is capable of competing with benchmark performances and even improving during fine-tuning. Its algorithm is influenced by the K hyperparameter that defines the context length and the interplay between exploration and exploitation.

Several distinct features mark out the ODT's algorithmic architecture, including the probability of the maximization of trajectory repeats and an auto-regressional model of...

A detailed exploration of implementing time series data in neural networks provides crucial insight into the hallmark of successful trading systems. Notably, setting the parameters accurately has a significant impact on the output, a factor often overlooked leading to distorted and less desirable results.

Valuable concepts such as 'Distances' take into account the space between different indicators. For instance, when direct input parameters like the value of the MA 1 indicator are passed to the system, the values exhibit an irregular spread over time, thus creating a statistical anomaly with vast ranges. However, if the difference between two indicators is passed, with examples being MA 1 and MA 100, or the value of the MACD indicator now versus its value four candles ago, the system can comprehend whether the market is extensively oversold or overbought compared to present insight...

Developing a personalized MT4/MT5 indicator for self-use or clientele is now simpler than ever. By integrating three lines of code into the MQL4/MQL5 file, scope for an indicator's functionality can be broadened exponentially.

With this upgrade, the indicator can establish a connection with Telegram, dispatch messages and signals to the platform, and even entertain trade instructions from the application. Furthermore, the incorporation of trading capabilities to an indicator (open, close and managing positions), transforms it into a multi-dimensional tool.

Once operational within the "eco-system", the indicator can easily attach to multiple charts across diverse pairs and timeframes. While it exhibits the potential to detect numerous trading opportunities every day, the absence of trading constraints makes it an unprecedentedly dynamic entity.

The challenge lies in transforming t...

The TimeGMT function enables correct GMT representation using local system data. Primarily used for session hours adjustments in trading activity, the TimeGMT function factors in the Daylight Savings Time (DST) adjustments. However, while testing in the strategy tester, discrepancies occur as TimeGMT equals TimeTradeServer, causing miscalculations.

To overcome this, a TimeGMT library has been developed to rectify the function for accurate GMT during strategy testing. It relies on macro substitution in the TimeGMT function to address gaps in test and live run scenarios.

In practical usage, the fix is applied only when a strategy tester is detected, working on the selected symbol and timeframe in the strategy tester. It also ensures that no calculation errors occur during weekends or public holidays, providing a low overhead and swift computation time.

To illustrate the library, a de...

Discover the power of MetaTrader 5's export and import functions and elevate programmatic exchange beyond average standards. Its capacity to save rates and ticks from or to the 'Symbols' dialogue is especially notable. Keep in mind, however, some restrictions might affect tick export, possibly excluding portions of the required history.

To address this challenge, MetaTrader 5 makes use of a script which exports any part of the desired history into a compatible CSV-format. This aligns seamlessly with the standard procedures for data export and import. Moreover, the script operates based on the current chart's symbol, retaining its array of rates and ticks over a specified date range into two separate CSV-files.

The convenience doesn't stop at data extraction. Indeed, the files, saved in the MQL5/Files folder, have identifiers attached. The file names will carry the symbol name, the ...

Continuing on with insights from the previous article on EA automation, a fundamental observation was illuminated: the possibility of a system malfunction exists, no matter how remote. This factor necessitates measures to minimize potential damage or side effects. It stands to emphasize that creating a 100% automated EA is not a simple task. The goal has never been to obtain a 'foolproof' system devoid of supervision. In fact, that flawed perception about automatic EAs, that they're "set it and forget it", is misguided. As automation increases, complexity and gravity of potential errors amplify. Runtime errors can arise and must be managed in real time, which when coupled with potential system vulnerabilities, create a tiring demand on supervising staff. Always consider some salient points of potential problems, casings shadow even in a seemingly 'perfectly' running system.

Understanding the importance of special/unique domains is pivotal to leveraging predictive power in price volatility for traders. The concept of multi-domains, a generalization of domains, welcomes the replication of elements capturing all necessary metadata. They prove substantial in delineating intricate relationships in trading practices.

Consider the scenario of a multidomain accommodating multiple data points, or in some instances, a singular data point. When the homomorphism set represents a multidimensional domain, there are bound to be identical elements in the source domain. For the codomain, normalization of data points ranging from -100 to +100 enables unique representation. The possibilities become limitless when considering multi-faceted parameters coupled with today's robust computational capabilities.

The leverage of relative-domains is not extensively covered, despit...
