"|| - condition cannot be a string"

[[Deleted]]

Hello!

if(Symbol() == "EURUSD" || "USDCAD")
Alert("...");

leads to the error "|| - condition cannot be a string"

How can I compare the chart to a  list of symbols?

Thanks in advance!

or

static string myList = "EURUSD, USDCAD, GBPUSD, USDJPY";
if (StringFind(Symbol(), myList) >= 0)

or

static string myList[] = { "EURUSD", "USDCAD", "GBPUSD", "USDJPY"};
for (int iList = ArraySize(myList) - 1; iList >= 0; iList--) if (Symbol() == myList[iList]) break;
if (iList) >= 0)

APeng, I think I prefer WHRoeder first answer there <edit: combination of WHRoeder first and second answer>, especially if the broker suddenly change the symbol name without telling us, for example they change EURUSD into EURUSDfx or EURUSDm or EURUSDwhatever.

static string myList[] = { "EURUSD", "USDCAD", "GBPUSD", "USDJPY"};

for (int iList = ArraySize(myList) - 1; iList >= 0; iList--) 
     {
     if (StringFind(myList[iList], Symbol()) >= 0) break;
     }

Print ("Symbol is number ", (iList + 1), "in array list." );
