I am thinking about subscribing to SierraChart hence the following questions: Can I connect to and auto trade with Ameritrade using Ameritrade data or if I want to can I use a different source of data or what is possible in this regard? What would be a good value in data if strategies have a one week average hold time with a minimum of one day? Would Barchart data be a good value and what about Ameritrade data? Can I auto trade a basket of stocks? Can I mix time frames in a strategy like 3 minute, 20 minute, and one day? Can I use Excel functions in Sierra Chart Excel like worksheets? For example how would I calculate Bollinger Bands?
