This EA prepare example for activate open and close order, next chapster we would find out how to.

Moving Average EA Open Order with Modify Take profit and Stop Loss

Moving Average EA Open Order with Modify Take profit and Stop Loss

In previous chapter we guide moving average properties. In this chapster we would coding Moving Average EA MQL4 for modify take profit and Stop Loss.

Mention to Forex Broker have the exchange digits show 3,5 and 4 digits, which modify Take profit and Stop Loss that depend on broker we trading.

Refer to properties code in this part are:

extern string TP_SL = " --- TP and Stop Loss ---";

extern bool Broke3_5Digits = True;

extern double My_TP = 10;

extern double My_SL = 10;

And Moving Average Properties part we would always change as below

//Add extern parameter as Label

extern string MovingAvr = " --- Moving Average parameter ---";

//Change from original

extern int    MovingPeriod  =12;

extern int    MovingShift   =6;

//Add properties

extern ENUM_TIMEFRAMES TimeFrameUsed = PERIOD_CURRENT;

extern ENUM_MA_METHOD   EMA_method1 = MODE_SMA;

extern ENUM_APPLIED_PRICE Applied_Price1 = PRICE_CLOSE;

In checking the open order we would add the condition to design broker digits using as follow

void CheckForOpen()

  {

   double ma;

   int    res;

// calculate TP and Stop Loss   

   double BrokerTPSell,BrokerTPBuy;

   double BrokerSLSell,BrokerSLBuy;

 if(Broke3_5Digits=True)

 { 

   if (My_TP!=0)

   {

    BrokerTPSell = Bid-((My_TP*Point)*10);

    BrokerTPBuy = Ask+((My_TP*Point)*10);

   }

   

   if (My_TP==0)

   {

    BrokerTPSell = 0;

    BrokerTPBuy = 0;

   }

   

   if (My_SL!=0)

   {

    BrokerSLSell = Bid+((My_SL*Point)*10);

    BrokerSLBuy = Ask-((My_SL*Point)*10);

   }

   

   if (My_SL==0)

   {

    BrokerSLSell = 0;

    BrokerSLBuy = 0;

   }

   

 }

 if(Broke3_5Digits=False)

 { 

   if (My_TP!=0)

   {

    BrokerTPSell = Bid-(My_TP*Point);

    BrokerTPBuy = Ask+(My_TP*Point);

   }

   

   if (My_TP==0)

   {

    BrokerTPSell = 0;

    BrokerTPBuy = 0;

   }

   

   if (My_SL!=0)

   {

    BrokerSLSell = Bid+(My_SL*Point);

    BrokerSLBuy = Ask-(My_SL*Point);

   }

   

   if (My_SL==0)

   {

    BrokerSLSell = 0;

    BrokerSLBuy = 0;

   }

   

 }

So the open order we would put the value from Moving Average EA as below

//--- go trading only for first tiks of new bar

   if(Volume[0]>1) return;

//--- get Moving Average 

  // original ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

  //new

  ma=iMA(NULL,TimeFrameUsed,MovingPeriod,MovingShift,EMA_method1,Applied_Price1,0);

//--- sell conditions

   if(Open[1]>ma && Close[1]<ma)

     {

      res=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,BrokerSLSell,BrokerTPSell,"",MAGICMA,0,Red);

     

      return;

     }

//--- buy conditions

   if(Open[1]<ma && Close[1]>ma)

     {

      res=OrderSend(Symbol(),OP_BUY,LotsOptimized(),Ask,3,BrokerSLBuy,BrokerTPBuy,"",MAGICMA,0,Blue);

      return;

     }

//---

  }

In next chapster we would detail for auto close order

Moving Average EA Open Order Function

Moving Average EA Open Order Function

Check open order EA MQL4 moving average have new function use as below

Function used for open order MQL4 moving average EA

long Volume[] Series array that contains tick volumes of each bar of the current chart

double Open[] Series array that contains open prices of each bar of the current chart.

double Close[] Series array that contains close prices for each bar of the current chart.

string  Symbol() Returns a text string with the name of the currency pair

int OrderSend
string	NULL
Int cmd
0	OP_BUY
1	OP_SELL
2	OP_BUYLIMIT
3	OP_SELLLIMIT
4	OP_BUYSTOP
5	OP_SELLSTOP
double volume	Number of lots
Double price	Order price (double Bid price for Sell, double Ask price for buy)
Int slippage	Maximum price slippage for buy or sell orders
double stoploss
double takeprofit
string comment=NULL	Order comment text. Last part of the comment may be changed by server
Int magic=0	Order magic number. May be used as user defined identifier
Datetime expiration=0	Order expiration time (for pending orders only)
color arrow_color=clrNONE	Color of open order

Mention to this EA example not have EA Setting properties for Take Profit and Stop Loss, so at first we would add this parameter in to EA properties as below, which TP and Stop Loss that for broker 5 digits that need specify Point*10 and broker 4 digits would specify Point.

Incase no TP and SL that we would specify 0 in to these part.

Properties for Moving Average Parameter as below

extern string TP_SL = " --- TP and Stop Loss ---";
extern bool Broke3_5Digits = True;
extern double My_TP = 10;
extern double My_SL = 10;

//Add extern parameter as Label
extern string MovingAvr = " --- Moving Average parameter ---";
//Change from original
extern int    MovingPeriod  =12;
extern int    MovingShift   =6;
//Add properties
extern ENUM_TIMEFRAMES TimeFrameUsed = PERIOD_CURRENT;
extern ENUM_MA_METHOD   EMA_method1 = MODE_SMA;
extern ENUM_APPLIED_PRICE Applied_Price1 = PRICE_CLOSE;

//+------------------------------------------------------------------+

//| Check for open order conditions                                  |

//+------------------------------------------------------------------+

void CheckForOpen()

  {

   double ma;

   int    res;

//--- go trading only for first tiks of new bar

   if(Volume[0]>1) return;

//--- get Moving Average 

  // original ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

  //new

  ma=iMA(NULL,TimeFrameUsed,MovingPeriod,MovingShift,EMA_method1,Applied_Price1,0);

//--- sell conditions

   if(Open[1]>ma && Close[1]<ma)

     {

      // old send sell order: res=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,0,0,"",MAGICMA,0,Red);

res=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,0,0,"",MAGICMA,0,Red);

      return;

     }

//--- buy conditions

   if(Open[1]<ma && Close[1]>ma)

     {

      res=OrderSend(Symbol(),OP_BUY,LotsOptimized(),Ask,3,0,0,"",MAGICMA,0,Blue);

      return;

     }

//---

  }

This Moving Average function that sell condition is Open[1]>ma && Close[1]<ma

Buy condition is Open[1]<ma && Close[1]>ma

in the next chapster would explain about auto close order part in case open order is not the right way.

EA MA Optimal Lot or Trading Money Management

Optimal Lot or Trading Money Management

Example MQL4 Code Moving Average EA Check Pending Order

In the last chapster we learn about how to build expert advisor properties and link the extern variable 

Moving Average EA function. In this chapster we would learn open order condition from MetaTrader 

Moving Average EA Code

Moving Average sample expert advisor by MetaQuotes designed the coding as 5 block of code

Calculate Pending order

Optimal Lot or Trading Money Management

Open order condition

Close order condition

Activate on Tick Function

This Chapter we would learn about Calculation The pending order.

 Calculate Pending order

Calculate Pending order including function as below

Function	Feature
int OrdersTotal();	Returns the number of market and pending orders.
bool OrderSelect	The function selects an order for further processing.
Order index or order ticket	number of ticket
Selecting flags
SELECT_BY_POS	index in the order pool
SELECT_BY_TICKET	index is order ticket
pool=MODE_TRADES
MODE_TRADES	opened and pending orders
MODE_HISTORY	closed and canceled order
string OrderSymbol();	The symbol name of the currently selected order
string Symbol();	Returns a text string with the name of the current financial
int OrderMagicNumber();	The identifying (magic) number of the currently selected order
int OrderType();
OP_BUY	buy order
OP_SELL	sell order
OP_BUYLIMIT	buy limit pending order
OP_BUYSTOP	buy stop pending order
OP_SELLLIMIT	sell limit pending order
OP_SELLSTOP	sell stop pending order

Mention to the code and using function in this part

Basic MQL4 Function creation example from document page of MQL4

Explian the code MA EA calculate pending order

First Step specify function name and return value to function

From the MA EA code this part would return Integer value to function, which when we would like to use this 

function that we should call this function with (string variable)

for(int i=0;i<OrdersTotal();i++) // check total pending order

if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) break; // no action if have pending order

//if have pending order Buy or Sell count buys and sells variable

if(OrderSymbol()==Symbol() && OrderMagicNumber()==MAGICMA)

        {

         if(OrderType()==OP_BUY)  buys++;

         if(OrderType()==OP_SELL) sells++;

        }

//--- return total orders pending

   if(buys>0) return(buys);

   else       return(-sells);

}

Check order pending by function OrderSelect, which command in this part would check total order pass minor function SELECT_BY_POS and trade was opened or trade pending MODE_TRADE.

This if not have pending order would call open order function pass OrderType function

This Chapter we learn about how to check pending order in next chapter we would learn about Optimal Lot or money management

iMA Function Moving Average from MetaQuotes Example

iMA Function Moving Average in MetaQuotes EA or Expert Advisor Examples have 2 lines use iMA function 

that's

ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

This we would learning how to build EA properties for this function

Basic variable Data Type

Every Vaiable should contain and specific data type as below

int (integers)

double (real numbers)

bool (Boolean values, that is logical values)

string (values of string type)

color (values of color type)

datetime (values of date and time)

Extern MQL4 Variable Group

1. Input Value directly (Like input to Edit Box) to the MQL4 EA properties

2. Input Value pass Boolean drop down list to the MQL4 EA properties

3. Input Value pass EA Methode Function

Time to change the properties of MetaQuotes EA or Expert Advisor Examples code

Function from original code

ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

This we would add 3 lines to select Time Frame, Moving Everage and Apply Price, so add code as below to EA properties 

Input Enum Variable to the Moving Average Function to the MQL4 code

We have 3 enum variable now

TimeFrameUsed

EMA_method1

Applied_Price1

from original iMA function in the code

ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

Change to

ma=iMA(NULL,TimeFrameUsed,MovingPeriod,MovingShift,EMA_method1,Applied_Price1,0);
