aktuelle Gesamtzahl -> siehe Grafik. Tatsächlich verbraucht weiß ich auch nicht im Moment. Da gilt glaube nur selber zählen. Hier die Regeln: Notes about Market Data use A market data line is considered “active” when visible.Each alarm always uses one line of market data whether or not you are viewing the asset that contains the alarm.Market data requested through an API has top priority, followed by data requested by alarms, and finally basic market data display. This means that if you are viewing a trading page that includes 100 lines of market data, and you also have price-activated alarms set for 6 other contracts, those 6 contracts will receive market data, and your trading page will only show data for 94 contracts.The option chains in the OptionTrader do not count against available market data lines.(http://www.interactivebrokers.com/en/software/tws/usersguidebook/getstarted/add_market_data.htm#XREF_45267_Notes_about_Market) Grüße
