[The exchange formulates L2 market usage specifications and strictly prohibits "detours"] On September 1, the exchange recently issued enhanced market non-display technical management specifications, drawing clear red lines for the use of enhanced market (L2) data, thereby standardizing data use and maintaining market fairness. The "Specifications" clearly stipulate the self-use and data forwarding of data. In terms of personal use of data, the "Specifications" require that it must be used in designated computer rooms for written approved purposes, and forwarding or external transmission through any interface is strictly prohibited. In terms of data forwarding, it is clearly prohibited to use optical splitters, market mirroring, etc. to bypass the forwarding system to provide data to users. It is not allowed to forward data to brokers, information providers and other member units for a fee or for free. Overseas users must report in advance and must bind their MAC address for verification. Industry insiders pointed out that this move aims to use the institutional "cage" to strictly prevent the abuse and improper dissemination of market data, prevent the use of data advantages to "detour and jump ahead", and further maintain market fairness.
