Shell Advance Brake Plus is the approved brake fluid for Ducati and is a DOT 5.1
It's the Dot 5 you have to stay away from, unless your lines, seals etc can handle it.
As well as the above tips on bleeding, once you've done the first fillon the resorvoir, work the lever a little to get any bubble out of the pipe that connects to the master cylinder. It'll get the fluid in the pipes quicker.
Filling a new system always takes longer than a fluid change, so stick with it and you'll be OK.
Once finished, leave the bike on the sidestand, bars turned so the master cylinder is high and then cable tie the brake lever back.
The pressure will squeeze any air out into the res'. You'll also see if there are any leaks
