Try posting a sample or a link to something that sounds like what you are looking for...
Edit: oops, thought the link was your website
To me it sounds like more sounds are layered in the sample. To make trance leads you mostly start with 2 heavy detuned saw waves. Maybe try using rectifier distortion as saturation and/or distortion. Add loads of reverb and/or delay. Maybe a pinch of noise... Fatten up with unison (play with unison detune)...
