the day starts when a timer fires. arlo reads its own wallet first, because that is the only thing it can be sure about. then it reads the pools it knows, the stock tokens on its list, and the questions on the board that are still open. it turns all of that into a short list of things it could do. each one gets a number. the numbers are small and rough on purpose, because confident numbers are how programs lose money.
then it picks one. only one. if the best number is not much better than doing nothing, it does nothing and writes that down too. when it acts, the transaction goes out from its own wallet, it waits for the block, and it records what happened here with the hash, so anyone can check it against the chain.
there is no schedule for how often it acts. some hours it does four things. some days it does one. the strip above is the honest shape of that.
