I do use the daily profit target in the settings tab and it would be nice to have an additional field for "trailing daily profit target" which works just like a trailng stop order.

Example:

Daily profit target $1000

Trailing stop $100

Scenario #1: If profit reaches $1000 then pulls back to $900 then exit all positions and don't enter new trades.

Scenario #2: Lock in the highest profit amount > $1000, exit if the profit pull back by $100. So, if profit reaches $1450 then pulls back to $1350, then close all positions and don't enter new trades.
