I was introduced to the concept of Wu Wei over a game of pocket billiards in Taipei, Taiwan. One of our Chinese opponents kept saying "woo way" while his partner was shooting. It led to a long discussion and they said the best translation was "easy does it". Of course, it gets more complicated if you dig into the Taoist roots. But the idea of "easy does it" or "don't force things" definitely applies to both pocket billiards and trading.
