Evaluate dynamic Variables

New comment
Hi,

I'm looking to see if you can evaluate dynamically created variables in MT4. Here's an example. Suppose that I have 3 external variables that should create 3 different trades. I want to be able to dynamically create the variables I use to generate the orders.

Example:

extern string symbol_1 = "EURUSD";
extern double lots_1 = 0.2;

extern string symbol_2 = "GBPUSD";
extern double lots_2 = 0.4;

extern string symbol_3 = "USDCHF";
extern double lots_3 = 0.1;

function start()
{
  for(int i=1; i<=3; i++)
  {
  string symbol = "symbol_"+i;
  string lots = "lots_"+i;

  OrderSend(symbol,OP_BUY, lots, MarketInfo(symbol,MODE_ASK), 2, NULL, NULL, "testing", magic, NULL, LimeGreen);
  }
}
Try this.

 
extern string symbol_1 = "EURUSD";
extern double lots_1 = 0.2;

extern string symbol_2 = "GBPUSD";
extern double lots_2 = 0.4;

extern string symbol_3 = "USDCHF";
extern double lots_3 = 0.1;

//-----------

string symbol[3] ;
double lots[3] ;

//-----------

function start()
{
symbol[0] = symbol_1;
lots[0] = lots_1;

symbol[1] = symbol_2;
lots[1] = lots_2;

symbol[2] = symbol_3;
lots[2] = lots_3;

  for(int i=0; i<3; i++)
  {
  OrderSend(symbol,OP_BUY, lots[i], MarketInfo(symbol[i],MODE_ASK), 2, NULL, NULL, "testing", magic, NULL, LimeGreen);
  }
}
