Possible to programmatically filter Market Watch symbols?

MQL Language
#1

is it possible to make expert or script to search all symbols with special conditions and filter them and show in market watch or anywhere else?if yes how?

for example i want to filter symbols to show me symbols by macd best postion to buy.

#2

Yes, it’s possible, the best solution is to develop an indicator for this, instead of EA or script, since EA is better to trade single symbol.

#3

but how ?how can i apply this to all symbols by code?

You can make use of the functions here: https://www.mql5.com/en/docs/marketinformation and https://www.mql5.com/en/docs/series.

Yes it is possible,

To get the name of all the symbols in the market watch, use SymbolsTotal() in a loop like this:

string  arrSymbols[];
     for(int j=0;j<=SymbolsTotal(true)-1;j++)
           { 
                arrSymbols[j]=SymbolName(j,true);
           }

And function for filter like this:

string Chiko_Filter(string symbol,int period,int shift) {

 if( iIchimoku(symbol,period,InpTenkan,InpKijun,InpSenkou,MODE_CHIKOUSPAN,shift)< iLow(symbol,period,shift))

     return "bear";

 else if( iIchimoku(symbol,period,InpTenkan,InpKijun,InpSenkou,MODE_CHIKOUSPAN,shift)>iHigh(symbol,period,shift)

     return "bull";

  return "no signal"; 

}

At the end check symbols by a function and put the results in an other array:

int intPeriod=Period();
   string  arrSignals[];
   int intShift=0;  //Current candle;
     for(int j=0;j<=SymbolsTotal(true)-1;j++)
           { 
               if(Chiko_Filter(arrSymbols[j],intPeriod,shift)=="bull")
                  arrSignals[j]="bull";
               else if(Chiko_Filter(arrSymbols[j],intPeriod,shift)=="bear")
                  arrSignals[j]="bear";
               else                   
                  arrSignals[j]="no signal";
           }

Of course you can also check all the time-frames

I don’t think the details needed.

Thanks a lot…
