Alternate Betting Dalembert - wanting to add to it.

Hello.
Im looking to alter the Dalembert system already posted by resetting back to default bet if the Total P/L is at the highest it has been so far. 
At the moment the system never seems to get back to the default bet because of consistent losses and the longer you use it the larger the swings become, even if you've reached a new ceiling on profit.  I'd like to reset on each ceiling but can't work out how to achieve it.
