Will the next >=5% single day change in the S&P 500 be an increase?

increase = YES

decrease = NO

How we define a "single day change":

If it ended on say, tuesday at 1000. And then at end of day weds it is 1100 or higher, or 900 or lower, then the answer is WEDNESDAY. Changes within a single day which aren't the closing price are irrelevant.

We take (end of prior day) => (end of day in question) as the change, so that we treat "overnight changes" as being part of the subsequent day.

Get Ṁ600 play money

bought Ṁ100 NO

Usually high volatility is bearish.

opened a Ṁ100 NO at 44% order

I am assuming this is not a trick question and it has to be greater than or equal to 5% in magnitude.

@HarrisonNathan yes. Is part of it unclear? I hate trick questions and meaningless resolutions
