I need to know how to fill an enum or get a drop down list, with a string array :))
I think that you have made enough posts in this forum so that you should know to use the code button (Alt+S) when pasting code!

the reply above has solved your problem already, if only the sequence in this enum be the same with the symbollist in your array[].
thus, you can use array index to get every symbol.
hello,
symbols in iso, very nice, but I need to get a drop down list from my string array, as the string array done it.
because it is a mixed list (forex, indice, ...)
and there are with + or . at the end of them. i just want to select one in that drop down list and use it wthi an indicator , but without open a chart.
so, may be the thing a need doesn't exit in mql4. i think to create a canvas to create a drop down list as I want.
okay thanks for that idea.
hve a nice day :))

hello,
good idea, but I need the list from any brokers not a static list, because there is more than forex.
from
SymbolName(a,0)
I get the whole pairs -> EURJPY+ or EURJPY. or EURJPY and that what I get from my string array and use in my code
the most easy way will to get my drop down list will be
extern string testArray[];
but I get
I need more search to get what I need
thanks a lot

Of course it was just an example.
You would have to use the actual names of the pairs you want to show in the input parameters drop down.
Additionally you can use
SYMBOL_CURRENCY_BASE And
SYMBOL_CURRENCY_PROFIT To solve incompatible pre and postfix issues among different brokers.

hello,
nice answer, I tested it for all kind of pairs and give currency only, I didn' know about that. very interesting.
thank to you to give me some very good way to get what I need :)
for my code I need the full string as my string array store in memory. I will use it to apply an indicator like MACD, STOCHASTIC or others.
I will not open a chart to apply that indicator on my pairs. Often we can see RAW , standart or pro trading account.
In the list about my own broker I get 2 kinds about pairs, one for standart account like that EURJPY and onre for RAW account like EURJPY+, I use the last to open a chart because my own account is linked with a RAW acount.
for what I want to code, the user will have to choice his pair on his own list that his broker gives.
Because of that, if I link a pair without the postfix the result should be different. often the price is diferent between a RAW and STandart account.
i think to use an extern string variable and the user will fill it with ; between each pair and I will check if that pair match with one in my string array I did creat before and that will be enough to get what I want.
EURJPY+;EURUSD+;.......
the drop down list in the properties indicator is implemented in the core of MT4 and MT4 coders didn't want to give the possibility to fill an enum from a string because about the security of MT4.
So I will use a more simple code as I wrote before.
MT4 is very good software but with some limitations linked to security or complexity.
Thanks again for the time you spend about my ask :))

Once you get all the symbols list from broker. Add the strings in array: TradePairsArr
Then you can try this to check for postfixes:
// Place this snippet inside your init function: string TradePairsArr[] = {"AUDUSD","EURUSD","GBPUSD","NZDUSD","USDCAD","USDCHF","USDJPY"}; for(int i=0; i < ArraySize(TradePairsArr); i++) { // Check suffixes string PostfixArray[8] = {".","..","+","i","m",".stp",".G","pro"}; string postfix = ""; int size = ArraySize(PostfixArray); for(int a=0; a < size; a++) { postfix = PostfixArray[a]; if(!IsSymbol(TradePairsArr[i]) && IsSymbol(TradePairsArr[i]+postfix)) { TradePairsArr[i] = TradePairsArr[i]+postfix; break; } } if(!IsSymbol(TradePairsArr[i]) && !IsSymbol(TradePairsArr[i]+postfix)) { Print("Symbol does not exist: " + TradePairsArr[i]); RemoveIndexFromArray(TradePairsArr, i); i--; } } //+------------------------------------------------------------------+ bool IsSymbol(string symbol) //+------------------------------------------------------------------+ { SymbolInfoDouble(symbol, SYMBOL_BID); return GetLastError() != ERR_UNKNOWN_SYMBOL; } //+------------------------------------------------------------------+ template <typename T> void RemoveIndexFromArray(T& A[], int iPos) //+------------------------------------------------------------------+ { int iLast; for(iLast = ArraySize(A) - 1; iPos < iLast; ++iPos) A[iPos] = A[iPos + 1]; ArrayResize(A, iLast); }
For Symbols list I just hard-code everything and give users an option to specify their own pair list in case if they use BTC or stocks etc.
And if symbol is not found on broker, user will get a message that Symbol does not exist.
enum ENUM_PT { Manual=0, // Own Pair list Core7=1, // Forex Core 7 Core14=2, // Forex Core 14 Core28=3, // All 28 pairs AUDPairs=6, // AUD pairs CADPairs=8, // CAD pairs EURPairs=5, // EUR pairs GBPPairs=7, // GBP pairs JPYPairs=4, // JPY pairs NZDPairs=9 // NZD pairs }; extern string OwnPairs = "EURUSD,BTCUSD,Facebook"; // Main Pair List(Comma Seperated) extern ENUM_PT PairsTrading = 0; // Main Pairs Preset string Core7Pairs[] = {"AUDUSD","EURUSD","GBPUSD","NZDUSD","USDCAD","USDCHF","USDJPY"}; string Core14Pairs[] = {"AUDJPY","AUDUSD","CHFJPY","EURCHF","EURGBP","EURJPY","EURUSD","GBPCHF","GBPJPY","GBPUSD","NZDJPY","NZDUSD","USDCHF","USDJPY"}; string Core28Pairs[] = {"AUDCAD","AUDCHF","AUDJPY","AUDNZD","AUDUSD","CADCHF","CADJPY","CHFJPY","EURAUD","EURCAD","EURCHF","EURGBP","EURJPY","EURNZD","EURUSD","GBPAUD","GBPCAD","GBPCHF","GBPJPY","GBPNZD","GBPUSD","NZDCAD","NZDCHF","NZDJPY","NZDUSD","USDCAD","USDCHF","USDJPY"}; string JPYPairs[] = {"AUDJPY","CADJPY","CHFJPY","EURJPY","GBPJPY","NZDJPY","USDJPY"}; string EURPairs[] = {"EURAUD","EURCAD","EURCHF","EURGBP","EURJPY","EURNZD","EURUSD"}; string AUDPairs[] = {"AUDCAD","AUDCHF","AUDJPY","AUDNZD","AUDUSD","EURAUD","GBPAUD"}; string GBPPairs[] = {"GBPAUD","GBPCAD","GBPCHF","GBPJPY","GBPNZD","GBPUSD","EURGBP"}; string CADPairs[] = {"CADCHF","CADJPY","AUDCAD","EURCAD","GBPCAD","NZDCAD","USDCAD"}; string NZDPairs[] = {"NZDCAD","NZDCHF","NZDJPY","NZDUSD","AUDNZD","EURNZD","GBPNZD"}; // Snippet in init function: if (PairsTrading == 0) StringSplit(OwnPairs,',',TradePairsArr); if (PairsTrading == 1) ArrayCopy(TradePairsArr,Core7Pairs); if (PairsTrading == 2) ArrayCopy(TradePairsArr,Core14Pairs); if (PairsTrading == 3) ArrayCopy(TradePairsArr,Core28Pairs); if (PairsTrading == 4) ArrayCopy(TradePairsArr,JPYPairs); if (PairsTrading == 5) ArrayCopy(TradePairsArr,EURPairs); if (PairsTrading == 6) ArrayCopy(TradePairsArr,AUDPairs); if (PairsTrading == 7) ArrayCopy(TradePairsArr,GBPPairs); if (PairsTrading == 8) ArrayCopy(TradePairsArr,CADPairs); if (PairsTrading == 9) ArrayCopy(TradePairsArr,NZDPairs); if (ArraySize(TradePairsArr) <= 0) { Print("No pairs to trade"); return(INIT_FAILED); }
You don't need that you can use SymbolInfoString() to get the base and profit currency without pre- and postfixes.
string base = SymbolInfoString(SymbolName(pos,1),SYMBOL_CURRENCY_BASE); string profit = SymbolInfoString(SymbolName(pos,1),SYMBOL_CURRENCY_PROFIT); string symbolname = base+profit;

Hello,
Thanks to read my question:
I got an array[x]
x=196 // number of strings grabbed by: SymbolsTotal(0)
I grab all name instrument and put them in that string array, for that it works well :)
Now I need to get a drop down list to show all names to the guy who will set his instrument in the properties window (indicator)
like "enum" or drop down list
But the string array can't work with extern or input
So if you can give me a path to get what I am looking for, that should be very nice :))
Thanks a lot and please have a nice day.
here is a small piece of my code about that string array[]
