Developers handling Expert Advisors (EAs) can benefit from integrating a code snippet designed to track account withdrawals effectively. Tracking withdrawals is crucial for adapting the EA's strategy, as many EAs remain on virtual private servers (VPS) to maintain consistent settings across time frames or chart templates. A common issue arises when EAs increase lot sizes to recover losses but fail to adjust them post-withdrawal, mistaking them for losses. This oversight can lead to strategies that unnecessarily escalate risk. Implementing this code will allow the EA to discern between withdrawals and losses, enabling it to decrease lot size after a withdrawal, thereby aligning risk strategy with the new account balance. Consider modifying the existing framework to incorporate this functionality, optimizing the EA's performance by maintaining an appropriate l...

Enhanced functionality has been introduced to your existing Expert Advisor, enabling withdrawal tracking on accounts where it is deployed. This addition assists in monitoring account withdrawals efficiently. Expert Advisors often run on VPS setups to maintain stability across parameter resets and chart changes. A key issue arises when these systems react to losses by increasing lot sizes without recognizing withdrawal transactions, which can skew trading strategies.

Withdrawal recognition is crucial because traditional EAs do not adjust lot sizes for withdrawals, only for losses. This adaptation is essential so that the EA can optimize its trading approach, ensuring sustainability by recalibrating lot sizes based on the actual account balance after withdrawals. The code modification not only monitors withdrawals but also intelligently adjusts the lot size relativ...

A new initiative is underway to develop an indicator for identifying ranging market periods using a standard object with a dynamic anchor point. This tool features a non-lagging mechanism with two operational modes; it determines ranges either through a set point threshold or dynamically using ATR with a multiplier. By default, ATR is utilized for its suitability in this function.

To enhance visibility, a pseudo chart distinct from the original is created, allowing for differential candle coloring within identified ranges. The logic behind range identification is straightforward, with customizable ATR period and multiplier inputs. These customizations allow users to define market ranges according to their personal trading strategy preferences, accommodating both long-term traders and scalpers in recognizing varying market activities.

This new indicator provides a significant shift from the traditional zigzag indicators commonly used in market analysis. Traditional zigzags focus on highlighting past market swings with an inherent delay to confirm new swings. They are based on price action and primarily used for analyzing historical pivot points rather than detecting real-time signals.

In contrast, this dynamic, trend-based zigzag operates without lag to the current bar by leveraging the SAR trend—a non-lagging, trend-following algorithm. Unlike previous trend-following zigzags, such as those based on the PSAR, which suffered from delays and produced invalid legs, this new approach ensures zero lag throughout its execution.

Integral to this structure is the backstep function, crucial for maintaining valid legs. By utilizing a specified number of lookback bars, it finds the highe...

Implementing efficient memory management in MQL5 is crucial for optimizing trading systems. Understanding stack and heap memory allocations, identifying memory lifecycle stages, and recognizing common pitfalls like excessive object creation or improper resource management can significantly enhance performance.

To measure and profile memory usage, developers can build custom tools due to the lack of native MQL5 support. Simple techniques involve setting benchmarks to study memory operations' execution speed, while memory pools can minimize allocation and deallocation overhead. Whether deploying object pools or advanced variable-size pools, managing memory manually improves performance consistency.

Understanding the nuances of control flow in programming is crucial, especially with statements like RETURN, BREAK, and CONTINUE. These statements manipulate the natural flow of loops and are key for efficient coding. The RETURN statement is often tied to function control, returning execution to the caller. It can end an application if misused in procedures like OnStart or OnInit, integral in environments like MetaTrader 5. BREAK is pivotal in exiting loops prematurely under specific conditions but can complicate when used in nested structures. CONTINUE demands caution, frequently leading to infinite loops if not managed properly. Grasping these concepts aids in writing robust, efficient code.

For Expert Advisor development within MetaTrader, handling the initiation of a new bar poses a unique challenge since there is no built-in OnNewBar() event. Instead, developers need to track the opening time of the most recent bar to identify changes that indicate a new bar has started. This approach is implemented by using a static variable within the OnTick() function to persist data about the bar's opening time across calls. This method ensures that even when OnTick() is exited, the variable retains its value, allowing the detection of a change in bar time. Special care should be taken when the EA is first attached to a chart, as the initial bar open detection will differ, needing adjusted logic. Code samples compatible with MQL4 and MQL5 are available in MetaEditor's "Public Projects" under "FMIC.
