is there better/another function?

Thanks,

Hi,

The formula is analyzed for each symbol. If you want to buy "SPY" then you must include that ticker in the symbols list of your trading system.

I don't know why you are adding the first "GetSeries("SPY",close,LastData)".

It should be:
buy = GetSeries("SPY",close,LastData) > sma( GetSeries("SPY",close,LastData),10);

And in that case the trading system will enter long SPY and GLD if SPY is above its moving average.

Yes i understand but if I want to buy only SPY it is possible via QS vector language?

Thank You,
