In trades we receive from ELEKTRON for Australia market for Equities, we saw many conditions that are delivered in FID GV4_TEXT. Some of the values for it are "S3XT", "XT", "SAXT", "L1XT", "C*STXT", etc., there are quite a few, probably around close to a hundred. We couldn't find any documentation about the meanings of them. We know a few by checking against IKON, for example, "S3XT" meaning Special Cross = T3. Where can we find some detailed explanations for them? Please advise. thanks
