Trading-depending-on-S-P-in-Blocks

I would like to add I criterion that the S&P 500 has to be bullish, in order to trade.

So, I want to ask, if it is possible to do that with building blocks: Let's say the 10 day moving average of the S&P 500 has to be on the rise, that the strategy procudes signals.

Or do you need programming to realize that?

Thanks you
Werner
