## Instructions

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



- The ticker symbol

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

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

- The total stock volume of the stock

- Add functionality to your script to return the stock with the "Greatest % increase", "Greatest % decrease", and "Greatest total volume".

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



## Requirements



### Retrieval of Data

The script loops through one quarter of stock data and reads/stores all of the following values from each row:

- Ticker symbol

- Volume of stock

- Open price

- Close price



### Column Creation

On the same worksheet as the raw data, or on a new worksheet, all columns were correctly created for:

- Ticker symbol

- Total stock volume

- Quarterly change ($)

- Percent change



### Conditional Formatting

Conditional formatting is applied correctly and appropriately to:

- Quarterly change column

- Percent change column



### Calculated Values

All three of the following values are calculated correctly and displayed in the output:

- Greatest % Increase

- Greatest % Decrease

- Greatest Total Volume



### Looping Across Worksheet

The VBA script can run on all sheets successfully.



### GitHub/GitLab Submission

All three of the following are uploaded to GitHub/GitLab:

- Screenshots of the results

- Separate VBA script files

- README file

## CODING_PROCESS



Reset Button- Andrew Lane provided this code in a study group we had with several classmates over the weekend and I used it after I had completed the assignment as it was very helpful to reset using a macro versus manually deleting the results



Greatest% Increase/Greatest Decrease- I researched how to write a code that would look up the maximum and minimum values. Initially, I struggled with the formula for calculating the greatest total volume and reached out to Andrew for advice, assuming the issue was related to the min/max formula and worked on that for awhile which you can see in my code the various attemps i was making with the max code for the volume. However, it turned out that the problem was with how I was resetting the volume for the total stock volume calculation. I had originally placed the volume = 0 reset after the loop, but while adjusting things to test different outputs, I mistakenly moved it before the loop without realizing how this affected the results. I didn’t notice the incorrect output until much later.



Message Box- Since the code takes some time to run, I added a message box at the end to display a notification when the code has finished running.
