Although Smart Tube Pro doesn't have a build in trade script it can work with (probably) any trade script out there.. we have clients who run their tubes successfully with Trade Pulse and ATX.
Smart Tube Pro has a huge sponsor database filled with over 750k of content either vids or pics. also many sponsors have or are working on XML feeds you can use.
