Execute function if variable x is more than variable y

New comment

Using MQL4, how can I execute a BUY order (seen below) if one variable x has a value of 1 and another variable y has a value of 3? I need it to work like this:

Variable x = 1

Variable y = 3

So if x is MORE THAN y, execute this script:

extern int TakeProfit = 10;
extern int StopLoss = 10;

void OnStart()
  {
   double TakeProfitLevel;
   double StopLossLevel; 

   TakeProfitLevel = Bid + TakeProfit*Point;
   StopLossLevel = Bid - StopLoss*Point;

   Alert("TakeProfitLevel = ", TakeProfitLevel);
   Alert("StopLossLevel = ", StopLossLevel);

   OrderSend("USDCAD", OP_BUY, 1.0, Ask, 10, StopLossLevel, TakeProfitLevel, "first order");
 

 }

And if x is LESS THAN y, execute this SELL script:

extern int TakeProfit = 10;
extern int StopLoss = 10;

void OnStart()
{
double TakeProfitLevel;
double StopLossLevel; 

TakeProfitLevel = Bid + TakeProfit*Point;
StopLossLevel = Bid - StopLoss*Point;

Alert("TakeProfitLevel = ", TakeProfitLevel);
Alert("StopLossLevel = ", StopLossLevel);

OrderSend("USDCAD", OP_SELL, 1.0, Ask, 10, StopLossLevel, TakeProfitLevel, "first order");
 

}

I'm struggling to find the MQL4 code which establishes variables which can then be compared against each other e.g. x > y and vice versa, so any help would be greatly appreciated.  
if(x>y)
   {
    //Execute Buy order
   }
else 
if(x<y)
   {
    //Execute Sell order
   }

.

pluck6:

 but how do I establish the variables? Would it be something like this:

var x = 1;

var y = 3;


That wouldn't make sense. There would have to be some conditions that would assign a value to the variables.

Finally, should I wrap this whole code within void OnStart() {} ?

Either that or in a function.

  • Before programing in MQL4, I suggest you first familiarise yourself with code in general such as in a language called "C".
  • After that, read through the "MQL4 Book/Tutorial" section on this site, which will introduce you to all the basic things you first need to learn, such as how to declare variables, etc.
  • When in doubt, and before posting here, always consult the Documentation, whether that be the Online Version on via the Help (F1) in the Editor/Compiler.
learn to code it, or pay someone. We're not going to code it FOR you.
