Fuzzy logic
This software component for MetaTrader 5 is built to enhance the capabilities of your trading environment. This Expert Advisor serves as automated trading software. It is utilized to monitor financial markets and execute trades based on predefined algorithmic rules, enabling precise position management without the need for constant manual oversight.
How to Setup and Use Fuzzy logic
1. Installation: Open the "File" menu, select "Open Data Folder," navigate to MQL/Experts, paste your file, and restart the terminal.
2. Activation: Drag the EA from the Navigator onto a chart, ensure "Allow live trading" is checked in the Common tab, and verify the AutoTrading button is green.
3. Optimization: Right-click your chart, choose "Expert List," click "Properties" to adjust inputs, and save your preferred setup as a set file for future use.
4. Maintenance: Regularly check the "Experts" tab in the terminal window to monitor trade logs and potential execution errors.
Frequently Asked Questions
Q: Why is my EA not opening trades? A: Check the "AutoTrading" button, ensure "Allow live trading" is enabled, and verify your broker allows automated trading on your account type.
Q: Can I run multiple EAs on one chart? A: No, each chart can only host one active EA; however, you can open multiple charts for different currency pairs to run several EAs.
Q: What does the "smiley face" icon mean? A: A smiley face in the top-right corner of the chart indicates the EA is successfully running; a frowny face means it is disabled.
Description & Settings
An assessment is made based on the values of five indicators (Gator, WPR, AC, DeMarker and RSI). Uses trapezoidal membership functions. Before sending a trade request, it checks if funds on the account are enough.
Parameters
For the time-frame H1.
There is a lot of theoretical material on fuzzy systems, so let's discuss this Expert Advisor:
1) An assessment is made based on the values of five indicators (Gator, WPR, AC, DeMarker and RSI). Uses trapezoidal membership functions.
2) Ranking and weights of values can be edited straight in the code.
3) As a basis for the fuzzy assessment (to buy, to sell, not to do anything), you can use not only the above indicators, but also other methods at your discretion.
In general, the EA code is designed for practical acquaintance with the techniques of fuzzy evaluation of the current market situation. It is recommended to use or modify it after reading the theory. You can start with materials on fuzzy evaluation fundamentals by A. Nedosekin (it describes a different technology, but contains a very good explanation of the theory).
Note:
If you want to add your own criteria for evaluation instead of the five built-in indicators, I recommend splitting such criteria into borders of fuzzy values (in the code - arrays arGator[7], etc.).
Do not attempt to over-optimize the parameters of the membership function (they are not available as external parameters in the code) — this will not give any substantial effect.
Try experimenting. I think that fuzzy logic is incomparable in terms of decision making.
