Shanghai, as one of the world's "shipping centers", successfully listed the container Index (European line) futures (hereinafter referred to as "EC") on August 18, 2023. Meanwhile, the market has been paying close attention to the EC high-frequency price signal tracking channel. In the existing market tracking habits, tracking SCFIS with the relatively leading SCFI index is one of the ways of market reference. However, the global shipping market is changing rapidly under the influence of geography, carbon finance and various economic cycle factors, and the global supply chain is facing lots of uncertainties in the medium and long term. Therefore, the market's desire for higher frequency and longer months price signals is becoming more obvious. In order to better serve the market demand, TRANTOR Data launched the "DSCFI" index to improve the accuracy and depth of EC research for the whole market.
