Multiple_Year_Stock_Data_Angelina.vb

'Create a script that loops through all the stocks for each quarter and outputs the following information:

'1-The ticker symbol

'2-Quarterly change from the opening price at the beginning of a given quarter to the closing price at the end of that quarter.

'3-The percentage change from the opening price at the beginning of a given quarter to the closing price at the end of that quarter.

'4-The total stock volume of the stock. The result should match the following image:

'5-Add functionality to your script to return the stock with the "Greatest % increase", "Greatest % decrease", and "Greatest total volume". The solution should match the following image:

'Make the appropriate adjustments to your VBA script to enable it to run on every worksheet (that is, every quarter) at once.

'note: Make sure to use conditional formatting that will highlight positive change in green and negative change in red.
