So, if I understand that right, when the page loads, (refreshes) it checks the time and if the time is past the specified time, it adds the amount?
Let's say I am buying a share for $10. If I sell the share on the same day BEFORE 3:30PM, it will be sold for $10, but if I keep the share past 3:30PM, I want the code to automatically add $1 (Taxes and such) once in the the price of the share in database, after that no matter how many days pass by, the price will remain the same. I've thought about CRON jobs, but I have no idea how to make/use them or set them up. Any direction or help is appreciated.
