Dear folks, please create the following marketscanner in ninjascript: All stocks available should be scanned, those chosen under a certain condition; have reference to a list. this list is for example: AAPL = NASDAQ SIEMENS = DAX KK = S&P500 As soon as the scanner shows the stocks; the corresponding reference title (like NASDAQ, DAX etc) is also shown and can be analysed.
