They are not seen as outside of the protocol but so far no one has come forward with a Gap Analysis proposal asking for extensions in this area. Your remark about historical data falls under the time range I mentioned before, "All Time" just being another type of time span. Feel free to participate and join a committee/working group. FIX is extended directly by its members/users so that it is a matter of time and effort that needs to be put in by those that are interested in the extension. I am interested and have ideas but have not had the requirement (yet) to move forward on this topic. > Thanks for the quick response Hanno. > > In addition to publishing sector/market level statistics, some may wish > to publish historical data (e.g. 52-week high, all time low, etc.).
