ROCIndicator veri karsilastirma

Question

private string ChooseSymbol()
		{
			//var enyuksek;
			string hisse = "";
			//var enyuksek =   ROCIndicator("GARAN", SymbolPeriod.Day, OHLCType.Close, 1);
			decimal enyuksek =0;//ROCIndicator("GARAN", SymbolPeriod.Day, OHLCType.Close, 1).CurrentValue;
			foreach (var symbol in _symbolList)
			{

				if ((enyuksek ) <   ROCIndicator(symbol, SymbolPeriod.Day, OHLCType.Close, 1).CurrentValue)
				{
					enyuksek =  ROCIndicator(symbol, SymbolPeriod.Day, OHLCType.Close, 1).CurrentValue;
					hisse = symbol.ToString();

				}
				Debug("hisse " + hisse);
				Debug("e " + enyuksek );
			}
			return hisse;
			//return string.Empty;
		}

´roc veri dondurmuyor gibi. 

Debug("hisse " + hisse);

Debug("e " + enyuksek );
