Need new Indicator command ( ToDo List )

Hi,

I like to work and use multi-paires & multi ut "Screening" Indicator.

i would like this indicator to change itself Symbol() and Period() in Main Windows to focus a spécial event according to computations...

so i'll need 2 News Commands : ( for futur release if many people think this, or also find it is a good idea ).

=> SetSymbol(string "EURUSD" );

=> SetPeriod( int 240 );

...

String SForex[2]={"EURUSD","GBPUSD"};

int i=0;

...

If (...) NewForex=SForex[i];

SetSymbol(NewForex);

...
