In our latest technical assessment, we explored integrating third-party libraries with MQL5 Algo Forge, focusing on the SmartATR library. Initially, manual cloning via Git worked to integrate the library, revealing MetaEditor's current limitations when handling external repositories. We found console commands a requirement for external code integration, as MetaEditor didn't fully support repository cloning without pre-existing correct permissions or context operations.

We explored an alternate approach: forking external repositories via the MQL5 Algo Forge web interface. Forking provides an independent copy where developers can make modifications, which is then visible in MetaEditor for streamlined repository management. This supports the open-source model, allowing for potential code contributions and efficient project backups.

Developing advanced trading systems involves understanding classical patterns and programming skills. A recent implementation in MQL5 focuses on the Shark Pattern system, a harmonic pattern based on pivot points and Fibonacci retracements/extensions. The system automates trade execution upon detecting a valid pattern, offering flexible entry, stop-loss, and take-profit options. The use of chart objects enhances pattern visualization, aiding in clarity and decision-making.

For implementation, key steps involve defining structures for swing pivots, employing logic to detect pattern criteria, and visual aesthetics for chart depiction. Testing through historical data ensures efficacy and reliability, while careful risk management remains essential.

A custom optimization function crafted for the MetaTrader 5 Strategy Tester, this script assists in analyzing test results beyond the typical use of Expert Advisors, indicators, or scripts. The code begins by collecting trade history from the tester, ensuring a minimum of 50 trades, and recognizing the initial deposit and testing periods. Trades are divided into In-Sample (IS) and Out-of-Sample (OOS) periods, facilitating a more robust analysis.

Thereafter, it calculates a series of metrics, covering factors like profitability, drawdown, Sharpe and Sortino ratios, and profit factor. Statistical analysis is conducted using Kolmogorov-Smirnov and Jarque-Bera tests. Strategy evaluation incorporates multiple dimensions: profitability, consistency, risk-adjusted performance, and statistical quality.

This code is applicable in various scenarios: strategy...

In the ongoing development of our market simulation system, key challenges arise from ensuring system security, reliability, and performance. An essential step in this process is to address information leakage through proper encapsulation. Within the C_Mouse class, we identified a flaw in the SetBuffer function's accessibility, which was rectified by relocating it, thereby enhancing system integrity.

Further, system performance issues became apparent during extensive feature use, traced back primarily to the mouse indicator's intensive buffer reading. This was mitigated by isolating buffer accesses and optimizing class variable storage versus repetitive function calls.

The system's updated architecture now reflects a more robust class hierarchy aimed at maintaining performance levels while allowing for scalability and adaptability in future developme...

The transition to MQL5 Algo Forge emphasizes leveraging community-contributed code. A crucial step involves integrating third-party libraries while ensuring code remains modifiable through personal forks. In Part 3, SmartATR was integrated into the SimpleCandles Expert Advisor, highlighting challenges in direct cloning. A structured workflow using forks resolved these issues, with changes proposed to original repositories via Pull Requests.

Publishing modifications involves committing or releasing new versions. For efficient version control, obsolete branches should be managed to prevent repository clutter. A branch is essentially a sequence of commits, which remain intact post-deletion. Locating prior branch states involves identifying specific commits and understanding Git concepts like tags and the HEAD pointer. Tags, especially lightweight ones, ...

Part 25 of the MQL5 series introduces the development of an Expert Advisor (EA) to automate trading by identifying trend lines for signals. Unlike the previous focus on support and resistance zones, trend lines are used to assess market direction and breakout points.

The EA requires the user to manually draw two trend lines and name them appropriately. It can handle both breakout and reversal trades, setting stop-loss and take-profit levels based on the latest candle's data. By processing the last five candles, the EA detects if a price breaks or reverses from a trend line, ensuring relevant market moves. The use of trend line names and chart IDs enhances precise monitoring and engagement, avoiding unnecessary trades.
