MQL4 Code Wizard (MT4)-MQL4 code generation tool

Example

Suppose a user wants to initialize an array to store symbols and their first order tickets. The wizard can provide the following code snippet with comments: ```mql4 int firstOrderTicketFor0 = -1; string symbols[]; // Array to store symbols int firstTickets[]; // Array to store the first ticket for each symbol int OnInit() { ArrayResize(symbols, 0); // Reset the array ArrayResize(firstTickets, 0); // Reset the array return(INIT_SUCCEEDED); } ```

Scenario

A trader is developing an Expert Advisor (EA) to manage orders based on the first order ticket for each symbol. The provided code snippet initializes and resets the necessary arrays when the EA is initialized.

Example

The wizard explains how to use the 'void OnTick()' function, which is crucial for actions that need to be performed with every tick. For instance: ```mql4 void OnTick() { double currentPrice = iClose(Symbol(), PERIOD_M1, 0); // Get the current closing price Print("Current price: ", currentPrice); } ```

Scenario

A user wants to log the current price of the asset every time there is a new tick. This function demonstrates how to retrieve and print the current closing price, helping the user implement real-time data handling in their script.

Example

The wizard explains where to place global and local variables in a script. For example: ```mql4 int orderCount; // Global variable void OnTick() { int localCounter = 0; // Local variable for(int i = 0; i < OrdersTotal(); i++) { if(OrderSelect(i, SELECT_BY_POS)) { localCounter++; } } orderCount = localCounter; Print("Total orders: ", orderCount); } ```

Scenario

A trader needs to count and print the total number of orders every tick. The wizard helps by explaining that 'orderCount' should be a global variable to retain its value across ticks, while 'localCounter' is a local variable used within the 'OnTick()' function.
