Stocks Optimization Puzzle

Working on an optimization puzzle where you are given lets say $500 and monthly stock values for stocks, and you have to sell/buy/short stocks each month until the end to try to get the most money. Will be using real stock data. Currently the main validators I want are a single stock where you have to short it, a single stock where you have to buy it, then just normal runs. Can anyone think of any other validators that would be necessary, or just any other cool ideas to go along with this?


Something like this should maybe be a multi. But I digress, nothing beats the real world.

I do think this will be fun as a multi, but I thought we already have so many of those and not a lot of optimization puzzles. It still works on the same algorithms. Nothing preventing adding a version to both, I would just rather go with this for now
