Expert Advisors and Their Optimization

The world of Forex trading has witnessed revolutionary changes with the advent of Expert Advisors (EAs). These are automated systems that allow traders to execute trades based on predefined criteria without human intervention. One of the most essential features of EAs is the ability to optimize them for better performance. Let’s dive deep into this process.

Optimization of Expert Advisors:

Optimization, at its core, is a rigorous process that allows traders to refine their trading strategy by testing various parameter combinations. By doing so, traders aim to identify the most profitable settings for their strategy.

Why Optimize?

1. Time Efficiency: The primary purpose of using optimization is time-saving. Manually back-testing an EA with varied parameters can be tedious and time-consuming. The optimization feature automates this task, producing comprehensive results in a fraction of the time.
2. Research Tool: Optimization can also serve as a research instrument. Different combinations of indicator parameters, Take Profit, and Stop Loss settings can lead to varied results. With the capability to test thousands of combinations, traders gain invaluable insights into which settings are the most profitable during backtesting.

Steps to Enable Optimization

1. Activation: Simply tick the box to switch from back-test to Optimization mode.
2. Parameters: You can define the Expert Advisor, Symbol, Model, and the time duration (Start and End dates). Spread choices are available, allowing traders to use the ‘Current’ spread or a predefined constant spread.
3. Optimization Settings: Clicking on the lets users define their optimization preferences. Users can choose the Genetic Algorithm, which might hasten the optimization process by predicting and skipping presumed unprofitable back-tests. However, one should remember that while it speeds up the process, there’s a risk of loss of accuracy as not every configuration is tested.

Input Parameters

Here lies the core of customization. Every EA has external parameters, accessible via the tab. Users can decide which parameters to optimize. By ticking checkboxes and setting Start, Step, and Stop values, traders instruct the optimizer on the nature and range of tests.

Optimization Process

Once the inputs are defined, traders can initiate the optimization. As the optimization begins, traders are provided with real-time insights, including the estimated time of completion and the number of expected combinations for back-tests.

A crucial aspect is the ‘Skip Useless Results’ option in the Optimization Results tab. By deselecting this, traders can view even the unprofitable back-tests, providing a holistic understanding of the strategy.

Post Optimization

Once optimization concludes, a detailed report showcasing every back-test’s Net Profit, Profit Factor, Expected Payoff, and Drawdown is available. Traders can also access an Optimization Graph, offering visual insights into the optimization process.

For those who wish to analyze an EA’s performance with a specific parameter set, a back-test can be run, enabling a deeper analysis of trade details.

VPS – Enhancing EA Performance

A Virtual Private Server (VPS) acts as a dedicated remote computer, enabling traders to run their EAs continuously. One of the primary benefits of using a VPS is reduced latency, ensuring quicker and more precise trade executions. FxPro, for instance, offers execution times of under 13ms. For traders in high-latency regions like China, using the FxPro VPS can substantially improve their trading experience.

Maximizing VPS Use

To ensure smooth performance, it’s recommended not to overload the VPS. Limiting to four MT4/MT5 platforms or a single cTrader platform with a cAlgo Bot is advisable. Additionally, the POM application, pre-installed on the VPS, ensures automated restart of applications after a VPS reboot, adding to the convenience.

FAQs about EAs and VPS

What is Expert Advisor optimization and why is it useful?

Expert Advisor optimization allows traders to test how their trading strategy performs under various parameters. It serves as an efficient alternative to manually back-testing an EA multiple times with different parameters, thus saving time. The Strategy Tester’s optimization feature automates this process and presents the results in an organized table.

How do I enable optimization?

To shift from back-test mode to Optimization mode, you simply have to check the box. After this, specify the Expert Advisor, Symbol, Model, and the Start and End dates, similar to setting up a back-test.

What are the general optimization settings and the role of the Genetic Algorithm?

In the general settings, you can choose whether or not to use the Genetic Algorithm and what value the EA should be optimized for. The Genetic Algorithm can expedite the optimization process by predicting and skipping likely unprofitable back-tests. However, using it might lead to potential loss in accuracy as not all input configurations are tried.

How can I determine which EA parameters to optimize?

Navigate to the tab to select the EA parameters for optimization. If the tab is missing, the EA doesn’t have any external parameters, and hence, cannot be optimized. By ticking the checkboxes, you can select specific parameters and set their Start, Step, and Stop values.

How does the optimization process begin and what should I expect to see?

After setting up the inputs, click and then the button. As the optimization commences, you’ll observe an estimated completion time and the total count of expected combinations for back-tests.

What are ‘Useless parameters’ and why should they not be skipped?

Once optimization starts, the Optimization Results and Optimization Graph tabs become accessible. It’s advisable to deselect ‘Skip Useless Results’ in the Optimization Results tab, ensuring that even back-tests that resulted in losses or had zero trades are shown. This helps in evaluating how the EA reacts with particular parameters.

How can I interpret the optimization results and visualize the data?

The results table provides metrics like Net Profit, Profit Factor, Expected Payoff, and Drawdown for each back-test along with the parameters used. Furthermore, the Optimization Graph can be viewed in both 2-D and scatter plot modes, showing optimized parameters against each other or the distribution of back-test results, respectively.

What is a VPS in relation to Expert Advisors and how do I get one?

A Virtual Private Server (VPS) is a remote computer allowing EAs to run continuously without downtime and ensures faster trade execution. A VPS can especially benefit traders in areas with high latency. To acquire a VPS from FxPro, visit their dedicated website page or contact their support via email. It’s free for VIP clients and $30 monthly for others.
