Each morning the trades are conducted with $5 each, which are mostly fractional shares that are bought.

You mean they add $5 in cash to each AI’s account? Because after dividends and sold shares they should have even more cash to work with.

Would be interesting to see the amount of fractional shares bought as well as its comparison in percentage to the total budget that day.

The fractional share is $5 divided by the share price. The bots each spend $5, so the percentage of the budget each spends is 1 divided by the arbitrary number of bots, so in this case 16.7%. Share price is an arbitrary value in that a company can split or reverse split at will. So both calculations would be arbitrary values.

Great point, I will add that to the recent trades table at the bottom. It should use the total budget for the day.
