Problems using index as second instrument

[saj816]

Hello,

I am able to backtest just fine if I use a stock for my second instrument.

Add("MSFT", PeriodType.Minute, 1);

However if I try to enter an index like NYSE TICKs I run into problems.

Add("$TICK", PeriodType.Minute, 1);

When I select the strategy in the backtester setup page, I get backtest results from the previously selected strategy. I also notice the parameters from the previously selected strategy stay in the backtest setup page as well. My quote source is TD Ameritrade.

Thank You for your help.

saj816, I'm not sure if TDA would support all indices available (like the TICK you added), do you see the same issues with for example adding the DJIA or the SP500 as second series to your strategy?
