This indicator creates an alert for a new trading day - as well as contains a variable that counts the number of bars that has passed since the trading day opened.
It posts the alert both on the chart and has an alert condition so it can be sent to you.

Updated the code to make it flow better, as well as cleaned up some variables. Added a high and low alert - it alerts when there is a new high or low being set during the trading day.
