hi;

in stock market we can recognize the chart with : " SymbolInfoString(_Symbol,SYMBOL_ISIN) "

if we have SYMBOL_ISIN for one of them and want to add it to market watch so, we must select it by : SymbolSelect(name,true);

but for stock market how can select from : SYMBOL_ISIN function ?

With a loop.

I know that. My question is "what doesn't work ?"

ChartSetSymbolPeriod() is a function, it returns a value, and what's the error code if any.

there is no error or warining , there is always : active_symbol="EMPTY" .

i add the high lighted line and get this :

.
.
if(SymbolInfoString(_Symbol,SYMBOL_ISIN)!=active_ISIN) ChartSetSymbolPeriod(0,active_symbol,0);
     else Print("Error  (",GetLastError(),")");
.
.
.

i found this : error 4301

Of course,"EMPTY" is not a valid symbol.

So, why the value of your symbol is still to "EMPTY" after running AddSymbolToMarketWatch() ?
