Dive into the fundamentals of static vs dynamic arrays with our latest exploration into ROM and RAM types in MQL5. Understanding these distinctions is crucial for algorithmic trading developers looking to optimize their code. ROM-type arrays, always static and immutable, mirror the behavior of read-only memory within your application. Meanwhile, RAM-type arrays offer dynamic flexibility, allowing their size and content to change during execution. These insights help developers manage memory effectively and avoid common pitfalls when handling elements, especially with arrays behaving like live variables in RAM. Enhance your technical skills and master array management for efficient and robust algorithmic trading code in MetaTrader 5.

In developing replay systems, handling asset auction states is crucial. Our aim is to accurately inform users about the auction status of a custom asset in a replay or simulation environment. Initially, a rule was set: if no trades occur within 60 seconds, the system notifies users of an auction state. This approach avoids unnecessary system complexity.

Recent updates involve significant changes to various code files, including C_Terminal.mqh and C_Mouse.mqh, enhancing our mouse indicator to consistently recognize order book events. This update supports both live and custom instruments, offering a unified interface for detecting market activity and auction states.

Key modifications include removing unnecessary initializations to avoid erroneous data handling and improving error reporting during initialization. In the updated system, the mouse indica...

An automated trading system is designed to manage market positions based on specific conditions. It operates based on the number of open positions. If fewer than a set number of positions are open, the system remains inactive. Upon reaching the specified position count, it will automatically close all previous positions if the total profit and loss (PnL) is positive. If the number of positions is equal to or exceeds the specified count, the system will close all positions once a positive PnL is achieved. This strategy prevents excessive risk by limiting the number of open positions while ensuring occasional profit capture. All positions must share an equal risk level, acknowledging the potential volatility differences across instruments.

Candle filtering is a significant feature of the indicator, allowing traders to focus on specific candle types. It supports filtering for Bullish, Bearish, and Doji candles, or displaying all candles with assigned colours. Doji candles are detected using a configurable threshold, ensuring accuracy in identification. The feature enables traders to define custom colours for each candle type, enhancing visual distinction. Default colour settings include green for Bullish, dark red for Bearish, and gold for Doji.

Chart cleaning improves visual analysis by removing elements such as grids and volumes. The initialisation phase maps buffers for OHLC values and assigns custom colours, while unnecessary elements are removed from the chart. In the main calculation phase, each candle’s compliance with the selected criterion determines its display colour. Upon the ...

Analyzing the combination of the Triple Exponential Moving Average Oscillator (TRIX) with the Williams Percent Range (WPR) offers insights into trend signals and market conditions. TRIX, a momentum oscillator using triple exponential moving averages, is valuable for filtering out noise and confirming trends. Its crossover above or below the zero line indicates potential trend reversals or confirmations. Meanwhile, the WPR identifies overbought and oversold conditions, serving to highlight support and resistance levels.

When testing these indicators on CHF JPY for the 4-hour time frame in 2023, ten distinct patterns emerged. Among these, the TRIX crossover paired with WPR pivoting can indicate trend shifts, and combining price divergence with TRIX and extreme WPR positions can suggest reversals. TRIX trending behavior with WPR position further r...

In a grid trading strategy, set the grid distance to manage orders based on price movements. For a price decrease meeting the grid-defined threshold, initiate a long order. Conversely, a price increase securing the grid distance justifies a short order. If the price advances triple the grid distance, close the position. The initial fund allocation for the position is one-tenth of the grid requirement, escalating to two-tenths successively. Upon reaching the predefined profit target, all positions close, and the strategy restarts.

For testing, backtest the EOS/USDT pair from January 1, 2021, to August 31, 2021, using default parameters. Additionally, evaluate the AUD/USD pair from the start of January to the end of June 2021. Such assessments help refine strategy effectiveness and performance.

Technical indicators are widely used by investors and present both opportunities and challenges. One significant issue is the lag inherent in technical indicators and determining the optimal period to use, which can significantly affect trading outcomes. Short periods often introduce noise, while long periods delay signals.

To address this, employing Dimension Reduction Algorithms, particularly Uniform Manifold Approximation and Projection (UMAP), can help optimize indicator periods. UMAP allows for a representation of all available data, revealing insights beyond the original dataset. Additionally, Object-Oriented Programming in MQL5 can enhance efficiency by managing namespace and memory, essential for building effective trading applications.

Creating graphical controls that can be bound to other elements is an efficient way of managing GUI in programming. A primary focus is developing functionality where moving a panel also moves all controls attached to it. This requires the programmer to handle GUI construction, as there's no built-in visual constructor within the terminal.

The existing library needs enhancements for this task. Defaults are set using macro substitutions within the library, such as color and shadow properties, which can be adjusted as needed. Furthermore, object hierarchy in the code must reflect logical arrangements to enable object grouping.

Introduced improvements include relative coordinates, enabling position specification based on an object's base. The library's virtual methods support descendant object handling, ensuring flexibility in object manipulation. Additionally, ...
