The spread parameter has been coded as a list of section variables, with an option to open all symbols on the market-watch. 

Usage is still simple.

//--- these are user input variables accessible from the terminal when launching the script  input ENUM_TIMEFRAMES Time_frame = NULL;  input spread Max_spread         = all_values;    //--- this is the SymbolInfo object(comes with the standard package) for ease of use of symbol properties.  CSymbolInfo m_symbol;      

We loop through the market-watch and check symbol properties(spread and availability on the market-watch) while checking the spread suitability through a function of type int maxSpread(), which  processes the user inputs.

The loop:

for(int i = 0; i < SymbolsTotal(true); i++) {            Pair = SymbolName(i, true);            if(Pair == SymbolName(i, true)) {                 if(m_symbol.Name(Pair)) {  //--- check spread propertiex                      int spread_limit = maxSpread(Max_spread);                      //---                      if(spread_limit == -1)                           ChartOpen(Pair, Time_frame);                      else if(m_symbol.Spread() < spread_limit)                           ChartOpen(Pair, Time_frame);                 }            }  //--- close the attached chart since another instance is opened.            if(i == 0)                 ChartClose(0);       }

Compile the file and launch it on any chart and select your preferred settings.
