关于WTI正价差/逆价差的新手问题

It's definitely used for both. Beyond just confirming directional bias, a lot of traders will absolutely structure spreads to capitalize on contango or backwardation, either calendar spreads or even more complex inter-commodity spreads if other related products are misaligned.

For many, it's primarily about spread trading, specifically calendar spreads. If you believe the market is overstating future demand or supply, you can profit from the shape of the curve correcting. Directional bias is a component, but the curve's shape itself offers more nuanced opportunities.

It's funny, every 'newbie' asks this. Many are indeed trading spreads – the ol' roll yield – but some certainly use it as a directional hint. If the market's paying you to hold, it's probably feeling pretty good about the future, right?
