Migration vs co-orbital planets

Perhaps some hints as to why no Trojan planets have shown up so far?

Mechanism operates for planets in the partial gap-opening regime where the ratio is less than a factor of two. Systems with more massive leading planets are more stable, as are systems where both planets are massive enough to open a full gap.
