How to use MQL generator?

<p>Understand the syntax of Monitoring Query Language (MQL) expressions and review valid values for interval, statistic, and predicate operators in MQL expressions.</p><p>MQL &nbsp;syntax governs expressions for querying metrics that are published to the Monitoring service. MQL expressions define queries (including alarm queries). MQL acts on aggregated data.&nbsp;</p><p id="isPasted"><em>Some components can appear in an MQL expression multiple times. For example, you can use two grouping functions (as in&nbsp;groupBy(), followed by a&nbsp;statistic, followed by&nbsp;grouping()). You can also&nbsp;nest queries.</em></p><p><em>You can also&nbsp;join multiple queries&nbsp;into a single query.</em></p><p><em>For alarms in the Console, the absent() statistic is listed under Operator.</em></p>

<p id="isPasted">To use an MQL generator (like the MQL5 Wizard), you follow a structured, no-code workflow to assemble trading components into an Expert Advisor (EA). This tool is built directly into the MetaEditor environment integrated with MetaTrader 5.&nbsp;</p><p><strong>1. Launching the Generator</strong></p><ul><li>Open MetaEditor: Launch MetaTrader 5 and press F4 or click the IDE button in the toolbar.</li><li>Start Wizard: Click New in the top-left corner and select Expert Advisor (generate) from the list of options.</li><li>Basic Settings: Give your EA a unique name and select the default symbol and timeframe it will operate on. </li></ul><p><strong>2. Defining Strategy Logic</strong></p><p>The generator uses three main modules to build the robot's "brain":&nbsp;</p><ul><li>Signal Module: Click Add to choose technical indicators (e.g., Moving Averages, MACD, or Stochastic). You can combine multiple signals and assign each a "weight" to determine its influence on trading decisions.</li><li>Trailing Stop Module: Select how the EA should protect open profits. Options include using a fixed Stop Level, a Moving Average, or Parabolic SAR.</li><li>Money Management Module: Define risk parameters, such as a fixed trade volume (e.g., 0.1 lots) or a percentage risk of the total deposit (e.g., 3% risk per trade). </li></ul><p><strong>3. Compilation and Testing</strong></p><ul><li>Generate Code: Click Finish to have the Wizard automatically write the MQL5 code.</li><li>Compile: Click the Compile button at the top of MetaEditor. This converts the source code into an executable file for the trading terminal.</li><li>Backtest: Return to MetaTrader, find your new EA in the Navigator window, right-click it, and select Test to run a historical performance check in the Strategy Tester. </li></ul><p><strong>Alternative MQL Generators</strong></p><p>If the built-in wizard is too limited, third-party tools offer more complex visual builders or AI-driven generation:&nbsp;</p><ul><li>Visual Builders: Tools like fxDreema, EATree, and StrategyQuant allow for drag-and-drop strategy creation without manual coding.</li><li>AI-Powered Assistants: Platforms such as ayondo's MQL AI Wizard allow you to describe strategy parameters in natural language to generate code. </li></ul>
