Understanding key mathematical concepts is critical for successful programming. One such imperative principle is the "Harmonic Mean". This numerical average is computed by the division of the total number of observations with the reciprocal of each respective figure in the series. It's noteworthy to state that the harmonic mean in itself is the reciprocal of the arithmetic mean of the reciprocals. It might sound complex, but once comprehended, it's a seamless tool in data structuring and manipulation.

Every budding and seasoned software developer should accustom themselves with this statistical tool as it's prevalent in algorithm efficiency evaluation and optimizing data query performances. Set a deliberate timer to study this fascinating concept to boost your software development expertise.

Over the years, neural networks, particularly those using 'supervised learning' methods like backpropagation neural networks (BPNN), have become essential tools for traders. Various modifications of such algorithms form the base for deep, recurrent, and convolutional neural networks. Let's take a moment to appreciate the recent introduction of new API features on the MQL5 platform designed for matrix and vector operations. These new functions permit batch computations in neural networks, where data processing happens in blocks rather than element by element. The use of matrix operations noticeably streamlines program instructions, converting complex operations into single-line expressions.

Delving deeper, it's worth noting that neural networks are typically comprised of simple computing elements—neurons—grouped into layers and interconnected through synapses. The current state of a n...

The application of a code block involves proficient use of a Stop Loss or its absence. The key facilitator is "Trade.mqh", a requisite for the CTrade class access. This class manages the interactions with positions and orders. Creating adjustable trailing distance invokes an input parameter, although not mandatory, it enhances convenience.

CTrade class needs an instance definition, with a non-specific naming convenience, and should be ideally set after the OnInt event handler. Validation for the presence of a running position initiates with an 'if' statement, further invoking the 'Check_TrailingStop()' function, applicable to each tick. This ensures an accurate and smooth trailing system.

Priority of the statement is highest at the commencement of the 'OnTick' event handler, ensuring optimal functionality. 'Check_TrailingStop()' is a user-centric function name that can be altered ...

The code block provided facilitates a dynamic detection system for a new bar or candle upon receipt. Functioning on a simple principle, its initial action stores the time of the preceding bar or candle, followed by an addition of sixty seconds to that time. This results in a closing time value for the current bar or candle. Once the current time equals this newly calculated closing time, it signifies receipt of a new symbol or closure of the existing one.

An integral part of this code is the flag - a Boolean variable dubbed 'NewBarReceived'. This smartly prevents multiple calls to this block of code, ensuring its execution is limited to once per bar or candle. Comment(); alongside playsound("ok.wav"); act as tools to verify the code block's accuracy. These can be removed based on user preference.

A reset of the flag to a false state occurs once current Time surpasses the closing tim...

Recently, the development team rolled out version 3 updates of the script. A new modification in this version allows the system to return a string that indicates whether the pip difference has gone up, stayed the same, or declined. One key feature of this version is that it now prints the price at the start and the end of each calculation.

Furthermore, it accurately calculates and displays the pip difference. The pip difference is computed as the difference between the prices during the commencement and the conclusion of the calculation. It is then converted into pips for comprehensive understanding.

One of the major enhancements added in this update is the direction of the pip difference. It can now indicate and print out the direction of the pip, providing more information for data analysis.

Version 3 also introduces a Point to Pip conversion factor. This function is added for s...

Reflecting the gravitational behavior of universal bodies, the Gravitational Search Algorithm (GSA) has been developed as a powerful tool to tackle optimization problems. Mirroring principles of Newton's law of gravitation, the algorithm uses an innovative approach dealing with particles as significant objects, creating a bridge between global physics and computational mathematics.

The algorithm highlights a massive natural force: gravity. While it is the weakest among all four fundamental forces, gravity is the force visible in most day-to-day events, like walking on Earth or the orbiting of planets around the Sun. Newton extrapolated the gravitational force's behavior into universal laws of motion, marking a cornerstone in classical mechanics. His laws have immense implications in the gravitational search algorithm.

The GSA, introduced in this in-depth article, operates on the ...

Analyzing the Simulated Annealing (SA) algorithm, that finds the global optimum in complex problems, based on the techniques in metallurgy involving heating and slow cooling of materials. It helps avoid local optima by the usage of a 'cooling' function, reducing the probability of routing towards a worse decision.

The SA optimization algorithm applies randomness in changing the state of the solution and selecting the next state, enabling exploration of different regions of the search space. It allows room for accepting worse decisions with certain probabilities and gradually reduces this likelihood over time.

Metahueristics use the SA optimization algorithm as one of their methods for solving complex optimization problems. The algorithm belongs to a group of algorithms known as "stochastic optimization methods". Offshoots of the SA include Adaptive Simulated Annealing (ASA) and Quan...
