Responsive Order Panel Trading Interface in MQL5

Introduction

Imagine executing trades with the precision of a master operator, using a sleek, user-friendly panel to place orders swiftly in dynamic markets. The Responsive Order Panel EA is your advanced trading interface, designed to streamline manual trade execution on MetaTrader 5. It features a compact panel with an editable text field ("txtName") for setting lot size (default 0.01, "lotsize") and two buttons ("buyName", "sellName") for opening buy or sell market orders at the current ask or bid price ("openTrade()", "obj_trade.PositionOpen()") via the "OnChartEvent()" handler. The panel, positioned in the chart’s top-left corner ("panelLoc=CORNER_LEFT_UPPER"), supports lot size adjustments through text input validation ("CHARTEVENT_OBJECT_ENDEDIT") and instant trade execution ("CHARTEVENT_OBJECT_CLICK") without stop loss or take profit settings. This non-trading EA suits traders seeking quick, manual control in volatile markets, complementing automated strategies with a flexible, intuitive interface.

This article is crafted with a professional, engaging, and seamless narrative, flowing like a well-designed trading console, designed to inform and captivate readers. Tailored for both novice and experienced traders, we’ll dissect each code component with clear, precise explanations, as if guiding an apprentice operator through a trade execution project. With vivid examples—like trading EURUSD—and a polished tone, we’ll explore how the EA initializes, creates the panel, handles events, executes trades, and ensures cleanup. Using a precision trading interface metaphor, this guide will illuminate the code’s technical rigor, empowering you to command your trading with confidence. Let’s activate the system and begin this interface expedition!

Strategy Blueprint

Let’s outline the EA’s interface framework, like drafting specifications for a trading control console:

• Panel Creation: Displays a panel with an editable lot size text field ("txtName") and buy/sell buttons ("buyName", "sellName") using "createPANEL()", "EditCreate()", "ButtonCreate()".

• Lot Size Input: Updates lot size ("lotsize") via text field edits ("CHARTEVENT_OBJECT_ENDEDIT", "StringToDouble()") with validation to prevent negative values.

• Trade Execution: Opens buy orders at ask or sell orders at bid ("openTrade()", "obj_trade.PositionOpen()") on button clicks ("CHARTEVENT_OBJECT_CLICK") without stop loss/take profit.

• Event Handling: Processes user interactions through "OnChartEvent()", ensuring responsive trade execution.

• Execution: Runs without automated trading logic, focusing on manual control in "OnChartEvent()".

• Enhancements: Adding stop loss/take profit inputs or a magic number could improve risk control and trade tracking. This framework streamlines manual trading with precision, offering a clear, intuitive interface for order execution.

Code Implementation

Let’s step into the trading interface control room and dissect the MQL5 code that powers this Responsive Order Panel EA. We’ll guide you through each phase like expert interface designers, ensuring the narrative flows seamlessly with professional clarity and engaging precision that captivates readers. We’ll cover initialization, panel creation, event handling, trade execution, and cleanup, with detailed explanations and examples—like trading EURUSD—to make it accessible for beginners. Each phase will build on the last, crafting a cohesive technical narrative that transforms code into a compelling trading interface project. Let’s power up the system and begin!

Phase 1: Constructing the Framework—Initialization

We start by building the interface system, initializing the panel for manual trade control.

CTrade obj_trade;

const ENUM_BASE_CORNER panelLoc = CORNER_LEFT_UPPER;
const int xMargin = 30;
const int yMargin = 50;
const int xSpace = 10;
const int ySpace = 10;
const int btnWidth = 100;
const int btnHeight = 50;
const int txtWidth = (btnWidth*2) +xSpace;
const int txtHeight = 40;
const int txtX = xMargin;
const int txtY = yMargin;
const int buyX = xMargin;
const int buyY = txtY+ySpace+btnHeight;
const int sellX = buyX+xSpace+btnWidth;
const int sellY = txtY+ySpace+btnHeight;
const string txtName = "txtvolume";
const string buyName = "buybtn";
const string sellName = "sellbtn";
double lotsize = 0.01;

int OnInit(){
   createPANEL();
   return(INIT_SUCCEEDED);
}

The system begins with the #property header, establishing copyright and contact details, like calibrating a trading interface’s core. The "OnInit()" function initializes the setup, including "Trade/Trade.mqh" for trading via "obj_trade". It defines constants for panel positioning ("panelLoc=CORNER_LEFT_UPPER", "xMargin"=30, "yMargin"=50), spacing ("xSpace"=10, "ySpace"=10), and element sizes ("btnWidth"=100, "btnHeight"=50, "txtWidth"=210, "txtHeight"=40). Element coordinates ("txtX", "buyX", "sellX", etc.) and names ("txtName", "buyName", "sellName") are set, with default lot size ("lotsize"=0.01). The "createPANEL()" function builds the interface. Returning INIT_SUCCEEDED signals, “Interface is ready, let’s trade!” This primes the EA for manual order execution, like a control console poised for action.

Phase 2: Designing the Interface—Creating the Panel

With the system initialized, we create the panel with text and buttons, like setting up a trading console.

void createPANEL(){
   ObjectDelete(0,txtName);
   ObjectDelete(0,buyName);
   ObjectDelete(0,sellName);
   EditCreate(0,txtName,0,txtX,txtY,txtWidth,txtHeight,(string)lotsize,"Arial",10,
              ALIGN_CENTER,false,CORNER_LEFT_UPPER);
   ButtonCreate(0,buyName,0,buyX,buyY,btnWidth,btnHeight,"BUY","Arial",10,
               CORNER_LEFT_UPPER,clrBlack,clrGreen,clrBlack);
   ButtonCreate(0,sellName,0,sellX,sellY,btnWidth,btnHeight,"SELL","Arial",10,
               CORNER_LEFT_UPPER,clrBlack,clrRed,clrBlack);
}

bool EditCreate(const long Chart_Id=0,const string name="Edit",const int sub_window=0,
               const int x=0,const int y=0,const int width=50,const int height=18,
               const string text="Text",const string font="Arial",const int fontsize=10,
               const ENUM_ALIGN_MODE align=ALIGN_CENTER,const bool readOnly=false,
               const ENUM_BASE_CORNER corner = CORNER_LEFT_UPPER,const color clr=clrBlack,
               const color bgcolor=clrWhite,const color borderclr=clrNONE,const bool back=false,
               const bool selection=false,const bool hidden=false, const long z_order=0){
   ResetLastError();
   if (!ObjectCreate(Chart_Id,name,OBJ_EDIT,sub_window,0,0)){
      Print(__FUNCTION__,": Failed to create the Edit Btn, error = ", GetLastError());
      return (false);
   }
   ObjectSetInteger(Chart_Id,name,OBJPROP_XDISTANCE,x);
   ObjectSetInteger(Chart_Id,name,OBJPROP_YDISTANCE,y);
   ObjectSetInteger(Chart_Id,name,OBJPROP_XSIZE,width);
   ObjectSetInteger(Chart_Id,name,OBJPROP_YSIZE,height);
   ObjectSetString(Chart_Id,name,OBJPROP_TEXT,text);
   ObjectSetString(Chart_Id,name,OBJPROP_FONT,font);
   ObjectSetInteger(Chart_Id,name,OBJPROP_FONTSIZE,fontsize);
   ObjectSetInteger(Chart_Id,name,OBJPROP_ALIGN,align);
   ObjectSetInteger(Chart_Id,name,OBJPROP_READONLY,readOnly);
   ObjectSetInteger(Chart_Id,name,OBJPROP_CORNER,corner);
   ObjectSetInteger(Chart_Id,name,OBJPROP_COLOR,clr);
   ObjectSetInteger(Chart_Id,name,OBJPROP_BGCOLOR,bgcolor);
   ObjectSetInteger(Chart_Id,name,OBJPROP_BORDER_COLOR,borderclr);
   ObjectSetInteger(Chart_Id,name,OBJPROP_BACK,back);
   ObjectSetInteger(Chart_Id,name,OBJPROP_SELECTABLE,selection);
   ObjectSetInteger(Chart_Id,name,OBJPROP_SELECTED,selection);
   ObjectSetInteger(Chart_Id,name,OBJPROP_HIDDEN,hidden);
   ObjectSetInteger(Chart_Id,name,OBJPROP_ZORDER,z_order);
   return (true);
}

bool ButtonCreate(const long Chart_Id=0,const string name="Button",const int sub_window=0,
               const int x=0,const int y=0,const int width=50,const int height=18,
               const string text="Text",const string font="Arial",const int fontsize=10,
               const ENUM_BASE_CORNER corner = CORNER_LEFT_UPPER,const color clr=clrBlack,
               const color bgcolor=C'236,233,216',const color borderclr=clrNONE,const bool back=false,
               const bool selection=false,const bool hidden=false, const long z_order=0){
   ResetLastError();
   if (!ObjectCreate(Chart_Id,name,OBJ_BUTTON,sub_window,0,0)){
      Print(__FUNCTION__,": Failed to create the Btn, error = ", GetLastError());
      return (false);
   }
   ObjectSetInteger(Chart_Id,name,OBJPROP_XDISTANCE,x);
   ObjectSetInteger(Chart_Id,name,OBJPROP_YDISTANCE,y);
   ObjectSetInteger(Chart_Id,name,OBJPROP_XSIZE,width);
   ObjectSetInteger(Chart_Id,name,OBJPROP_YSIZE,height);
   ObjectSetString(Chart_Id,name,OBJPROP_TEXT,text);
   ObjectSetString(Chart_Id,name,OBJPROP_FONT,font);
   ObjectSetInteger(Chart_Id,name,OBJPROP_FONTSIZE,fontsize);
   ObjectSetInteger(Chart_Id,name,OBJPROP_CORNER,corner);
   ObjectSetInteger(Chart_Id,name,OBJPROP_COLOR,clr);
   ObjectSetInteger(Chart_Id,name,OBJPROP_BGCOLOR,bgcolor);
   ObjectSetInteger(Chart_Id,name,OBJPROP_BORDER_COLOR,borderclr);
   ObjectSetInteger(Chart_Id,name,OBJPROP_BACK,back);
   ObjectSetInteger(Chart_Id,name,OBJPROP_SELECTABLE,selection);
   ObjectSetInteger(Chart_Id,name,OBJPROP_SELECTED,selection);
   ObjectSetInteger(Chart_Id,name,OBJPROP_HIDDEN,hidden);
   ObjectSetInteger(Chart_Id,name,OBJPROP_ZORDER,z_order);
   return (true);
}

In the interface design hub, "createPANEL()" removes existing objects ("ObjectDelete()") and creates a text field ("EditCreate()", "OBJ_EDIT") at ("txtX"=30, "txtY"=50, width=210, height=40) for lot size ("(string)lotsize") and two buttons ("ButtonCreate()", "OBJ_BUTTON") at ("buyX"=30, "buyY"=100) and ("sellX"=140, "sellY"=100) for “BUY” (green, "clrGreen") and “SELL” (red, "clrRed"), styled with Arial font ("fontsize"=10). Functions "EditCreate()" and "ButtonCreate()" use "ObjectCreate()", "ObjectSetInteger()", "ObjectSetString()" with error handling ("ResetLastError()", "GetLastError()") to ensure robust rendering. For example, on EURUSD H1, the panel shows a lot size field (0.01) and buy/sell buttons, like a sleek trading console.

Phase 3: Handling Interactions—Processing User Inputs

With the panel created, we process user interactions to update lot size and execute trades, like operating a control console.

void OnChartEvent(const int id,
                  const long &lparam,
                  const double &dparam,
                  const string &sparam){
   if (id==CHARTEVENT_OBJECT_ENDEDIT){
      string lotsText = ObjectGetString(0,txtName,OBJPROP_TEXT);
      double newLot = StringToDouble(lotsText);
      if (newLot < 0){
         Print("Invalid value specified");
         return;
      }
      lotsize = newLot;
      ObjectSetString(0,txtName,OBJPROP_TEXT,(string)lotsize);
      return;
   }
   else if (id==CHARTEVENT_OBJECT_CLICK){
      if (sparam==buyName){
         ObjectSetInteger(0,buyName,OBJPROP_STATE,false);
         openTrade(ORDER_TYPE_BUY,lotsize);
         return;
      }
      else if (sparam==sellName){
         ObjectSetInteger(0,sellName,OBJPROP_STATE,false);
         ChartRedraw();
         openTrade(ORDER_TYPE_SELL,lotsize);
         return;
      }
   }
}

In the interaction hub, "OnChartEvent()" handles two events. For text field edits ("CHARTEVENT_OBJECT_ENDEDIT"), it retrieves the input ("ObjectGetString()", "lotsText") and converts it to a double ("StringToDouble()", "newLot"). If valid ("newLot >= 0"), it updates "lotsize" and refreshes the field ("ObjectSetString()", (string)lotsize); otherwise, it logs an error ("Print()"). For button clicks ("CHARTEVENT_OBJECT_CLICK"), it resets button state ("OBJPROP_STATE=false") and calls "openTrade()": for "buyName", it opens a buy at ask; for "sellName", a sell at bid, with "ChartRedraw()" for sells. For example, on EURUSD, editing lot size to 0.1 and clicking “BUY” opens a 0.1-lot buy at 1.2007, like operating a responsive console.

Phase 4: Executing Trades—Opening Market Orders

With interactions processed, we execute trades based on user inputs, like launching orders from a console.

bool openTrade(ENUM_ORDER_TYPE type, double vol){
   double price;
   if (type==ORDER_TYPE_BUY){
      price = SymbolInfoDouble(_Symbol,SYMBOL_ASK);
   }
   else price = SymbolInfoDouble(_Symbol,SYMBOL_BID);
   return obj_trade.PositionOpen(_Symbol,type,vol,price,0,0,"");
}

In the trade execution hub, "openTrade()" opens a market order ("obj_trade.PositionOpen()") using the specified type ("ORDER_TYPE_BUY" or "ORDER_TYPE_SELL") and volume ("vol", "lotsize"). It sets the price to ask for buys or bid for sells ("SymbolInfoDouble()") with no stop loss or take profit ("0,0") and an empty comment (""). For example, on EURUSD, clicking “SELL” with "lotsize"=0.1 opens a 0.1-lot sell at bid=1.2005, like executing a precise order.

Phase 5: Shutting Down the System—Cleaning Up Resources

As our expedition concludes, we shut down the system, ensuring resources are cleared.

void OnDeinit(const int reason){
   ObjectDelete(0,txtName);
   ObjectDelete(0,buyName);
   ObjectDelete(0,sellName);
}

In the shutdown control room, "OnDeinit()" removes the text field and buttons ("ObjectDelete()", "txtName", "buyName", "sellName"), like dismantling a trading console, ensuring a clean chart for the next task.
