Show HN: Where Will It Close?

It's a proof of concept to see if people will engage with the market as a game. It should be pretty obvious I'm no designer, but the algo behind it is pretty cool taking into account various factors when awarding scores at market close, including: - volatility that day - when the prediction was made - how close to the actual close the prediction was

Would love HN's feedback on what next steps should be to get people to give it a go.

Given how turbulent the market has been recently, thought it would be a fun few hour detour from my normal work.

I think you should definitely expound a little bit upon why it would be interesting for a casual user to make a prediction--that is, why should I bother? Will there be a reward of some kind?

You should also explain what makes this interesting. This should be something easy to digest and difficult to miss. You could also include a page which explains how the algorithm works in a little more detail for those who are interested.
