Tester Symbol Count is always 1

Hey, when I test my EA with more than one symbol still the symbol count is only one.

When this one will be incremented when I add more symbols to my test

Here's my code

string symbolList[2] = {"EURUSD","USDJPY"};

bool isTradeAllowed = true;

int OnInit(){
   return(INIT_SUCCEEDED);
}

void OnTick(){
   if(isTradeAllowed){
      PlaceBuyOrder(symbolList[0]);
      PlaceBuyOrder(symbolList[1]);
      isTradeAllowed = false;
   }
}

void PlaceBuyOrder(string currentSymbol){
   double ask = NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits);
   trade.Buy(lotSize,currentSymbol,ask);

Also when I visualize this test. Only selected symbol in the tester is showing and calculating. The other pair is not getting calculated.

How to test multi symbols without using All Market Watch Symbol Option

Is there a way to do it?

 
  1. You are not showing the code the prints out the symbol count you mention so we have no ideia how you are calculating it.
  2. When optimizing over all symbols, the EA is run against each symbol individually as the current symbol.
    So the EA should trade the current symbol only and not a predefined list of symbols set by you in the EA's parameters.
  3. If your EA trades multiple symbols from a list, then there is no use in optimising it against ALL symbols from the Market Watch. That only makes sense for single-symbol EAs, not multi-symbol EAs.

MT5 Strategy Tester (all market watch symbols)

That is because when you select "all market watch symbols" you are not optimising parameters, but in fact running a single test against each symbol, with the same parameters for all of them.

In other words, you are optimising to see which symbol offers the best results for the exact same parameters for all of them.

To truely optimise for multiple symbols, you have to code your EA to be multi-symbol and make the symbol selection be part of the parameters.

Here are two examples by different programmers from the CodeBase, but you should do your own research.
