RE:

can anyone insert the part of code in bold?

the program checks the spread, if the spread is greater than max spred then it must add a random symbol and check otherwise it must continue.

please help me

 

....

 private Random random = new Random();

        protected override void OnStart()
        {
            _stochastic = Indicators.StochasticOscillator(K_Period, Slow_K, D_Period, maType);

            var spread = Symbol.Ask - Symbol.Bid;

            while (spread > MaxSpread)
            {
                Print("Spread suck, go in other asset");
                Print(Symbols[random.Next(Symbols.Count)]);
                //must open another symbol and verify that the condition of spread> maxspread is true or false
            }

            Print("Spread Ok");

is this my problem

....

I would do it a completely different way.

Something along the lines of:

bool spreadOK = false;
double spread = 0;
int numberOfSymbols = Symbols.Count
int numberOfSymbolsChecked = 0;

while (!spreadOk && numberOfSymbolsChecked < numberOfSymbols)
{
  Symbol s = Symbols[random.Next(Symbols.Count)];
  spread = s.Ask - s.Bid;
  if (spread <= MaxSpread)
    spreadOk = true;
  numberOfSymbolsChecked += 1;
}

if (!spreadOk)
  Print("Could not find any valid symbols with a good spread.");

il programma controlla lo spread, se lo spread è maggiore di max spred deve è aggiunta un ispere e controlla altrimenti deve.

The problem is the line:

Symbol s = Symbols[random.Next(Symbols.Count)];

That lines doesn't return a Symbol object, but a string that's the name of the symbol.

You will need to use

Symbols.GetSymbol

to convert the string name to an actual Symbol object.

So first change the line to:

string symbolName = Symbols[random.Next(Symbols.Count)];

and then you need to add in and complete the line:

Symbol s = Symbols.GetSymbol....
