Reversing transactions Let’s hope you will not need it

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

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

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
