10. Optional project
Write a join that connects your confirmation tickets to the error messages produced by Athens
Create a button to visualize the results of that query

11. Reversing transactions
Let’s hope you will not need it

12. Reversing transactions
Reversing a transaction that was executed
Reversing a transaction that was NOT executed
Something went wrong

13. Reversing a transaction that was executed
You need to execute on the next day a manual reverse transaction
Example
Buy 1,000 Apple  Sell 1,000 Apple
This will not get you back to the exact same place

14. Reversing a transaction that was NOT executed
No need to execute a reverse transaction. Must manually modify your Acquired position Table.
Example
“Buy 1,000 Apple for $102,000” did not go through.
You need to manually subtract 1,000 Apple from AP, and
add back $102,000 to your Capital Account.
This will get you back to the exact same place
