Percentage Trailing DLL from a user defined high watermark.

The current trailing DLL is a great feature, but I think it would be greatly improved with a percentage figure from a user defined high watermark. Compared to a fixed value as it is currently.

For example, set your high watermark at $3000. Set your trailing DD at 50 % of the high watermark.

If your P&L drops to $1500, your account is locked out for the day.
