Overview: 

To view your biggest loss, do the following:

1. In Holdem Manager, navigate to Cash Games > Hands.
2. Under the Player Name field, select All. All your hand histories will populate, be patient as this may take awhile.
3. Click on the dollar ($) column twice. Losing hands will now appear in pink and the amount lost will be preceded by a negative sign. You can right click a hand history to access certain hand functions such as replay hand, copy to clipboard to post to forums, etc.

Play the embedded video for detailed instructions on how to review your biggest losing hands.

Note: It is important to review your biggest loss after every session.
